1. From acetaldehyde and ethanol in the presence of anhydrous calcium chloride and a small amount of inorganic acid in the role of the resulting oil, dried over anhydrous potassium carbonate, and then fractionation, collecting 101-103.5 ° C distillate, is the finished product. Refining methods: The main impurities are ethanol, acetaldehyde, paraformaldehyde, peroxide and so on. Alkaline hydrogen peroxide can be refined at 40 ~ 45 ℃ for 1 hour. Sodium chloride was added until saturation and the organic layer was separated. After drying with anhydrous potassium carbonate, sodium metal was distilled off. The aldehyde can also be oxidized by stirring with alkaline hydrogen peroxide at 65 ° C and then washed with water, dried over anhydrous potassium carbonate, filtered and sodium metal is distilled off. With controlled temperature of 8 ° C, freshly distilled acetaldehyde is slowly added to a theoretical amount of 95% ethanol and granular anhydrous calcium chloride, with a small amount of mineral acid condensation reaction. After the reaction, the upper solution was separated, washed with a small amount of water, dried over anhydrous potassium carbonate and dehydrated. And then distillation under atmospheric pressure, collecting 101 ~ 103.5 ° C fractions, after which the collected fractions were distilled again 1 or 2 times to obtain the finished product.
