Product Applications

Used as emulsifier, wetting agent, penetrant, diffusion agent, etc. It is also used as a component of cotton fiber and viscose cord thread oil agent. Used as emulsifier in the production of polyurethane foam. The food industry is used as ice cream emulsifier, and the dosage is 0.1%. When butter and general oil are used as emulsifier, the dosage is 1%..

Production method

1. Heat sorbitol to vacuum distillation, collect 60-85 ℃(8.0kPa) to steam out the water to achieve the calculation amount, take advantage of the heat to discharge, gain and loss of water sorbitol. It is acidified with oleate to get sdish 80. Then, schezer 80 and ethylene oxide were condensed under alkali catalysis to obtain Twain 80.

2. Add 360kg saucer 60 into the stainless steel stirring reactor, heat and melt, stir, then add 50% potassium hydroxide solution 8kg, seal the reactor, vacuum for dehydration and air removal. When the material temperature rises to 110 ~ 120℃ and there is no water droplets or water mist on the inner surface of mirros on the kettle, dehydration is completed. After filling dry nitrogen for several times to replace the air, the vacuum was stopped, the temperature was raised to 140℃, and ethylene oxide was started to be introduced. The reaction temperature is controlled to be 160 ~ 180℃, and the pressure is not more than 0.2MPa. When the incoming ethylene oxide is close to 800kg, the cloud point of the reactant is measured by sampling. When the cloud point of 1% active substance in 10% sodium chloride solution reaches 58 ~ 62℃, the reaction will reach the end point. Cool the product to 80-90 °c, add glacial acetic acid under stirring, and adjust the pH value to 5-7. Then, 12~15kg hydrogen peroxide is added dropwise under stirring for bleaching. After stirring for 1 hour, it is cooled and discharged, and the finished product 1100kg can be obtained.

3. Put 1 mol of The preheated splaten 8 0 into the reaction kettle, add the catalyst amount of sodium hydroxide under stirring, heat up, and vacuum with nitrogen to replace the air in the kettle, the temperature is controlled at 1 30~1 40 ℃ and 5 m o l ethylene oxide is introduced, and the reaction temperature is maintained at 1 50~1 60 ℃. After passing through the ethylene oxide aftercooling, put the feed liquid into the neutralization kettle and adjust the acid value to about 2 with glacial acetic acid, then decolorize with hydrogen peroxide, and finally dehydrate for 5 hours to obtain the finished product.
