| Abstract: | The catalytic synthesis of acetals by use of tungsten silicic acid from aldehyde and alco-hol reacting directly was researched. The available reacting conditions are the molar ratio of aldehyde and alcohol by 1/2. 5(mol/mol);the amount of catalyzer by 0. 5 g/mol aldelydetand the water-carrying a-gent by cyclohexane. The aftertreatment is simple and no"three waste pollutions". |
