Phenylarsine oxide solution - Production method
Mix phenylarsenic acid, methanol, and concentrated hydrochloric acid in a weight ratio of 1:5:2, add a little potassium iodide, and then add sulfur dioxide to saturation. Dissolve the oily benzene dichloro arsenic generated by the reaction with sodium hydroxide solution, and then neutralize it with hydrochloric acid to precipitate the benzene arsenic oxygen.
