2-ethylhexyl glycidyl ether reacted with acetone to produce ethylhexylglycerin

Using boron trifluoride diethyl ether as a catalyst, molar ratio of catalyst to 2-ethylhexyl glycidyl ether is 1:40, molar ratio of 2-ethylhexyl glycidyl ether to acetone is 1:6, and acetone is added 2 Ethylhexyl glycidyl ether and a catalyst were reacted at 20 ° C for 3 h to form a 4-alkoxymethyl-1,3-dioxane solution. The methylamine aqueous solution of the terminator was added in a molar ratio of the terminator to 2-ethylhexyl glycidyl ether of 1:8 for 10 to 20 minutes, and excess acetone was distilled off under reduced pressure. The formic acid and water were added for hydrolysis, and reacted at 55 ° C for 3 h. After the hydrolyzate is separated, the oil phase is neutralized with a base, washed to neutrality, and a stabilizer is added. Molecular distillation was carried out at a temperature of 135 to 145 ° C and a vacuum of 40 to 50 Pa to finally obtain high-purity ethylhexylglycerol.
