| Abstract: | 2,2-Diethoxypropane was prepared by acetone and anhydrous alcohol under triethyl or- thoformate as dehydration agent and ammonium chloride as catalyst.Effects of reaction condition on the condenstion were investigated,according to the method of single factor test.The preferably condition was that acetone 26 g (0.45 mol),triethyl orthofomate 74 g (0.50 mol),alcohol 75 mL and ammonium chloride 0.72 g were reacted under reflux for 3 h.The yield was 77.5%. |
