1,2-octanediol use and synthesis method

1,2-octanediol is a colorless liquid or white solid, and its boiling point (℃) under 1330Pa conditions is 131-132℃. 1,2-octanediol can be mixed with a variety of organic chemicals in any ratio, and has good formulation compatibility.

Add formic acid and hydrogen peroxide to a reactor equipped with a stirring and a thermometer and a high-level tank, start stirring, and then add 1-octene. After the addition, the reaction mixture solution is kept for 100 minutes, and then evaporated under reduced pressure Formic acid and water, then add sodium hydroxide solution under stirring until the pH value of the mixture solution is alkaline, and then add ester extraction, the resulting extract is washed twice with 30% sodium chloride, the washed extract After dehydration with anhydrous magnesium sulfate, distillation under reduced pressure, the distillate is collected under the condition of 131℃/1330Pa, and the obtained distillate is the product 1,2-octanediol.
