Synthesis method

Originated from benzoin through oxidation and transposition. Benzoin is oxidized with nitric acid to obtain bibenzoyl, which is added to the sodium hydroxide solution. -font-family: Tahoma”>100-110℃Reaction6h, dilute with water, and then adjust with dilute sulfuric acid pHTo3.5-4.0. Remove the floating oil and add activated carbon to decolorize0.5h, Filter, add sulfuric acid to the filtrate to pHpHValue is2, filtered, washed, and dried to obtain the finished product. Another method is to react benzoin with potassium bromate: combine benzoin, water, sodium hydroxide, and potassium bromate in a solution.

Purpose

Stomach Rehabilitation intermediate. Zirconium can also be determined.
