Sucrose benzoate is used as a synthetic chemical raw material, paint and cosmetics raw material, and as a high-performance rate modification additive for high-performance liquid crystal display film optical materials, holographic photographic sensitive materials, electronic image recording components, as well as for thermal transfer printing, magnetic thermal transfer ribbon, electrostatic spraying color powder and thermal printing ink. The average degree of substitution and the content of each component of sucrose benzoate are required in different applications to achieve better use effect. Sucrose benzoate is white to almost white powder, which can be used as plasticizer for solid ink, solid paint, thermosetting powder coating and hot printing toner. In a 250ml conical bottle, 40.0g sucrose (116.8mmol), 60ml water, and 20g 48% sodium hydroxide solution were added. The light yellow transparent sodium sucrose alcohol solution was dissolved by stirring at 35-40 ℃, and then transferred to a constant pressure drip funnel for use. Add benzoyl chloride 57Chemicalbook.9g (412.1mmol) into a 500ml four-necked bottle equipped with an ice bath, a blender, a thermometer and the aforementioned constant pressure drip funnel, control the temperature of the material by 5~10℃, and add the above sodium sucrose alcohol aqueous solution. As the reaction proceeds, the material gradually thickens, and 180ml toluene is slowly added to reduce the viscosity. The sodium sucrose alcohol aqueous solution is dripped for about 30 minutes, and then 16g of 48% sodium hydroxide aqueous solution is added to the constant pressure drip funnel, and 48% sodium hydroxide aqueous solution is added to the reaction system. At the same time, the temperature of the material is controlled by 5~10℃, PH8~11, and then the material is slowly heated to 20 ~ 25℃, and the thermal reaction is held for 2 hours. After the heat preservation reaction, heat up to 65~70℃, remove the water layer, wash the organic layer to neutral, water 20ml each time, wash 4 times (washing water for the next batch of synthesis or washing). Toluene recovered by organic layer distillation was poured into stainless steel tray while hot. After cooling, 79.1g of transparent glassy solid sucrose benzoate was obtained with an average degree of substitution of 3.5. The utilization rate of sucrose was 95.8% and that of acyl chloride was 95.1%. Use as paint, ink, plastic auxiliaries
