Preparation of Bromoacetaldehyde diethyl acetal: it is obtained by bromide, alcoholysis of vinyl acetate. Mixing vinyl acetate and ethanol at -10 °C. Slowly dropping bromine to maintain -5 °C under stirring. Gradually heated to 60 °C maintained for 1h, cooled to 10 °C, and 1 times the amount of ice water added. Add ammonia to make pH = 6 and double the amount of ice water to separate oil. Collect distillate under 71-76 °C (2.67kPa) by vacuum distillation to get the product.
Uses of Bromoacetaldehyde diethyl acetal: it is mainly used for synthesis of antibiotics such as erythromycin and cephalosporins and to other drugs. It also can be used as pharmaceutical intermediates. Besides, this chemical can be used to pruduce drugs such as methylthio imidazole, chlorpheniramine and others for thyroid.
