Potassium perfluorooctanesulfonate Use and Manufacturing

Methods of Manufacturing

Add anhydrous hydrogen fluoride to the electrolytic cell, and perform electrolytic drying at about 15V. When the current drops to a certain value, add octyl sulfonic acid, control the voltage 4 ~ 15 V, the current intensity 0.1 ~ 2A, temperature 10 ~ 15 ℃, proceed Electrochemical fluorination reaction. The reaction product is periodically discharged from the bottom, and the raw materials are added until the plate is passivated. The reaction product is fluorine octylsulfonate. Reserve after refining. In the salt washing kettle, add 95% ethanol and deionized water equal to ethanol in advance, and then add certain potassium hydroxide and calcium oxide to raise the temperature to 70 ℃. Then, the metered fluorine of octylsulfonic acid was added dropwise with stirring. When the pH reached 7, the reaction was terminated. Filter while hot. Remove filter residue. The filtrate is cooled, crystallized, filtered, and dried to be the finished product.

Uses

This product is used as a chromium mist inhibitor. It is added quantitatively during chromium electroplating, and a fine foam layer of a certain thickness is formed during electrolysis, which effectively inhibits the release of acid mist. Protect the environment and save chromic anhydride.Chrome mist inhibitor, wetting agent, fluoroprotein type foam fire extinguishing agent in electroplating
