8.6 Sodium alcohol: Sodium alcoholate is prepared by sodium metal added into the corresponding alcohol. It is hygroscopic white powder. It can decompose into alcohol and sodium hydroxide with water. It is widely used in organic synthesis reactions. In particular sodium ethoxide can be used as condensing agent. Sodium methanolate is a kind of common acatalyst. Because that its hygroscopicity is not as strong as sodium ethylate and its property is more stable, it is easy to control the quality when prepared. Sodium methanolate and sodium ethylate are two kinds of sodium alcoholate commonly used in the industry. The two both can be used as condensation agent and esterifying agent (such as the condensation and esterification of ethyl acetate, acetylacetone, methyl, ethyl malonate, barbiturates, drugs amino acids, glycerol esters); pharmaceutical raw materials and reagents (barbituric acid and its derivatives, sulfonamides, vitamins, antipyrine, chloroquine, amino acids, quinacrine, phenylbutazone, etc.); dye (yellow sand, methyl violet, tartrazine, toluidine, etc.); spices (false ionone, cyclamen aldehyde, indole and the like); grease modified aspect, preparation of fatty acid ester, non-ionic surfactant and pesticides. Sodium methanolate can be used as catalyst for the transesterification of fats. Transesterification can improve grease properties, such as improving grease shape retention and ductility.
Sodium methanolate can be prepared by the reaction of methanol with metallic sodium in the laboratory. It can be prepared by the reaction of methanol with sodium hydroxide in the industry. The relevant chemical reaction formulas are as follows: Sodium methanolate can be prepared by the reaction of methanol with metallic sodium in the laboratory.

8.7 Soda process for producing sodium methylate: Sodium methylate is prepared by the reaction of methanol with sodium hydroxide for soda method. Their reaction is as follows:
CH3OH + NaOH→CH3ONa + H2O
1. The preparation of methanol lye
Crush the solid sodium hydroxide. Then add it into melting pot base containing methanol (99.8%) in proportion. Start circulating pump, and dissolve the sodium hydroxide below 70℃. When its content is 20% to 23%, cool down to 40℃ and inject into the settling tank. Stand 12h and spare.
2. The preparation of sodium methylate
Pass into the steam to the vaporization pot and reaction tower mezzanine. Heat it and control the temperature at 85~100℃. Add anhydrous methanol to vaporization pot at the flow rate of 180L/h. Meanwhile add methanol lye in the top of the reaction tower at the flow rate of 25kg/h. Methanol gas containing 2% of water produced by the reaction from the reaction distill the reaction tower overhead into the purification distillation column to remove water. Then it becomes absolute methanol recycling. Control the temperature of reaction bottoms (i.e. vaporization pot) at 65~70℃, and check the bottoms. When containing 27%~31% Sodium methanolate, 1% or less of the free base, products are obtained. The yield is 86% (as sodium hydroxide).
Fixed consumption of the process is as follows: methanol (95%) 973kg/t, sodium hydroxide (99.5%) 209kg/t.; View all

8.8 Sodium process for producing sodium methylate: Sodium metal and methanol as raw materials, using intermittent production process to produce methanol solution of sodium methylate. The reaction is as follows:
2CH3OH + 2Na→2CH3ONa + H2↑
The production process is mainly divided into four parts:
1. Feeding step. Industrial methanol is pumped into methanol metering tank. 120kg of sodium metal is added into the reaction kettle.
2. Nitrogen substitution step. Close feed valve and vent valve. Purged with nitrogen into the reactor so that the index reached 0.1MPa. Open vent valve to remove the pressure, and repeat three times under reflux. The vent valve remains open to continue introducing nitrogen.
3. Reaction step. The cooling water is fed to the condenser. Methanol is immediately added to the methanol tank (note methanol addition rate). Nitrogen is stopped after 5~10min. Methanol is continuously added. 820kg of methanol is added in 2~3h and then the feed valve is closed. The reaction is continued for 2~3h until the reaction mixture has no bubbles.
4. Reconciliation step. The product is added into the harmonic tank. Sample and analysis. Reconcile to the desired concentration and barrels.; View all

8.9 The comparison soda process with sodium process: The content of methanol alkaline get by sodium method is higher, more reliable and stable than alkaline method. And the content of free alkali is low. Sodium methylate prepared by sodium method can take off a lot of alcohol and other impurities from sodium in the reaction. The content of Na2CO3 in sodium method is lower than in alkaline method, which can improve product quality and yield of the users.

8.10 Solution quality reference standard: Item Index
Appearance colorless to pale yellow viscous liquid
Content (total base number) 29.5%～31.0%
Sodium methoxide (NaOCH3) 28.9%～31.0%
Sodium hydroxide (NaOH) ≤0.5%
Sodium carbonate (Na2CO3) ≤0.1%
Water (H2O) ≤0.2%
Methanol 69.0%～70.7%

8.11 How to separate solid sodium hydroxide and sodium methylate: 1. Dissolved in water (sodium alcoholate reacts violently with water to generate alcohol and sodium hydroxide)
2. Distillation (separate alcohol)
3. Evaporation (separate sodium hydroxide)
4. Try to dry alcohol to anhydrous state (repeated distillation)
5. Add sodium to generate sodium alcohol
6. Distill alcohol to get solid alcohol sodium. (It should be avoided being exposed to the air when distilling. If it is exposed to the air or it is taken down before drying up and cooling, the state of alcohol sodium that is separated out is not well. The good one is white. if not, it will be tan is. But it doesn’t have any great impact. It is easy to be prepared.)

8.12 Production Process: Solid sodium hydroxide and methanol mix at a certain proportion. After stirring the mixture to dissolve, solid impurities are removed by sedimentation and clarification. The clear liquid is pumped into the top of the dehydration reaction column, while the refined methanol vapor is added from the bottom of the tower with continuous dehydration reaction. Then the product can be obtained from tower bottom. Aqueous methanol vapor is purified from the top of the column into the distillation system, while anhydrous methanol can be used repeatedly.

8.13 Identification test: It can react with oxygen and carbon dioxide. It decomposes in water. Sodium test of the solution (IT-28) is positive.

Remove the capsule of a sample bottle and let the sample bottle along the border quickly slid into a 500ml Erlenmeyer flask, which contains 200ml ice water removal of the carbon dioxide. Splashing should be prevented. Immediately plug flask with a rubber stopper, and shake to dissolve the sample. The sample is washed by decarbonation water into a 250ml volumetric flask, and dilute to the mark with almost. When the solution is allowed to reach room temperature, add water to constant volume and mixed. Take 50.0ml of the solution and transfer to 500ml conical flask with glass stopper. Add 150ml decarbonation water and 5ml barium chloride test solution (TS-37). Keep for 5min after the flask is stoppered and the solution is mixed. Add 3 drop Phenolphthalein test solution (TS-167), and titrate with 1mol/L hydrochloric acid until the pink color disappears. Reserve the titrated solution for the determination of sodium carbonate.

Immediately stopper iodine bottle to prevent moisture absorption and end disappearing. The amount of solution B added should not be counted. Add 50ml standard methanol/water solution that 1ml methanol contains 1.0mg water into the iodine bottle. Immediately titrate it with solution B to the same brown. Calculate equivalent factor F: the mass of water in 1ml solution B (mg). This calibration work should be required on a daily basis.
Select two 120ml jars with plastic screw cap. Firstly wash the two jars with hydrochloric acid, and then rinse them with water. Finally rinse them with isopropyl alcohol and dry them with airflow. Drill a hole in the spare plastic screw cap so that it can be accessed in an automatic burette tip. Add a magnetic stirring rod into each bottle, and flow dry nitrogen to remove carbon dioxide. Add 30ml solution A and 1.5ml anhydrous methanol into each bottle, and screw on the lid. Take the auxiliary lid to replace one of them, insert the tip of the burette, and start to stir. Titrate it with solution B to brown, and maintain that at least 5min. Change to the original lid. Titrate another solution in the same way. Remove the lids of the two bottles. Accurately weigh 2g sample from the prepared samples in one of the two bottles by reduction method and add the sample into another. Reconnect the lid on the two bottles. Titrate it with solution B (the first one bottle) to brown. And then titrate the blank (only the second bottle). Percent of water A in the sample is calculated as follows:
A(%) = (F×V×100)/(w×1000)

8.17 Production method: 1. Xylene (water content < 0.05) and metallic sodium are added into reaction vessel. Heat the reaction vessel to 130～140℃, keep for 1h and stop heating. After rapid stirring for 1h, use cooling water to 50℃. Then start to dropwise add anhydrous methanol (water content < 0.1%), and appropriately add dry xylene. The dropping rate depends on the flow rate of methanol and the release of hydrogen. After the dropwise addition finishes, heat it under reflux for 4h and cool to room temperature to obtain sodium methanolate slurry. Xylene can be recovered by vacuum distillation and then dried in vacuo for 4h. Sodium methanolate can be obtained by nitrogen cooling. The yield is over 90%. Sodium methanolate can also be prepared by the continuous reaction and dehydration of sodium hydroxide with methanol at 85～100℃.
