实验过程

To a mixture of 970 ml of anhydrous, 100% strength nitric acid and 3380 ml of anhydrous hydrofluoric acid were added dropwise at -10° C. in the course of 5 hours 1250 g (11.3 mol) of 2,3-dichloropropene. The reaction was exothermic. After the dropwise addition had ceased, the mixture was poured on to ice. The organic phase was separated off and washed with a large quantity of water. This gave 1316 g of moist product (=66% of theory) having a purity of 97%. The water content of the product was 0.5%.
