Synthesis method
Arsinization of phenol and arsinic acid Produced by chemical reaction. Dissolve arsenic acid in water and heat the solution to 180℃, dehydrate and concentrate and then cool to 110℃. Add phenol, add phenol to >℃Stir the reaction 28h. Add water until the relative density of the solution is 1.85-1.90, cool to precipitate crystals, and filter to obtain crude product. The mother liquor is arsenic acid, which can be used after treatment. The crude product is recrystallized with water and decolorized with activated carbon to obtain p-hydroxyphenylarsonic acid. Another preparation method is to diazotize p-aminophenylarsonic acid and then hydrolyze it.
Purpose
P-hydroxyphenylarsinic acid is an anti- It is an intermediate of spirochetal disease drugs and disinfectants, and is also a reagent for detecting titanium and zirconium.
