Synthesis method

Originated from acetylation of 1.3-amino-4-hydroxyphenylarsonic acid. Add 3-amino-4-hydroxyphenylarsonic acid to 5% sodium hydroxide solution and stir until completely dissolved. Adjust pH to 8, heat to 30-35°C, add acetic anhydride under vigorous stirring to precipitate, continue stirring for 1 hour, add hydrochloric acid at 55-60°C to precipitate crystals, filter, and wash with water to obtain crude acetylsamine. Refining: Dissolve the crude product in 5% sodium hydroxide solution, add activated carbon, stir, filter, and slowly add 10% sulfuric acid to the filtrate to make the Congo red test paper turn blue and precipitate crystals. Filter and wash to obtain refined acetylsamine.

Purpose

1. Medicine. Disinfectant, has the effect of killing trichomoniasis, and is used to treat vaginal trichomoniasis. It is often made into Diweijing tablets, each tablet contains 0.25g of acetylsamine and 0.30g of boric acid.
