Reaction Conditions:
with trichloroacetonitrile;triphenylphosphine in dichloromethane at 30;Inert atmosphere;Temperature;
Steps:
4-6 Example 6: Synthesis of isobutyryl chloride
In a 2L flask provided with thermometer, drying tube and stirrer, 88.11 g of isobutyric acid (1.00 mol) and 216.59 g Cl3CCN (1.50 mol) were added. 500 ml of dichloromethane was added and stirred at 30 ° C under nitrogen. 393.44 g of triphenylphosphine (1.50 mol) was added, and the progress of the reaction was monitored by GC. After the reaction, dichloromethane and low boiling materials or impurities were recovered, distilled at atmospheric pressure to remove low boiling liquid, heat distillation was carried out. The mass of isobutyryl chloride collected at a temperature of 91-93 ° C was 106.29 g, the yield was 99.76%, and the GC content was 99.65%.
