Reaction Conditions:
with sulfuric acid in water at 45 - 55;Reflux;
Steps:
3
In a four-necked flask equipped with a stirrer, a reflux condenser and a thermometer, 160 ml of 70% sulfuric acid was added, 38 g of 2-mercaptobenzothiazole was added, dissolved in a sulfuric acid solution, and a small amount of 21.2 g Acrylic acid, at 45 ° C to 55 ° C for 2 to 3 hours to produce intermediate compounds; diluted with water, the reaction material, filtration, filter cake with 10% sodium carbonate solution dissolved again filtered to remove insoluble material, the filtrate with dilute sulfuric acid solution Acidified to pH 1 to 2, the target again precipitation, filtration, washing, intermediate compounds were purified.
