Trifluoroacetic acid (TFA, CF ∝ COOH) is a highly volatile perfluorinated organic acid with much stronger acidity than ordinary acetic acid. It is miscible with water and most organic solvents and is mainly used in organic synthesis, biomedicine, analytical chromatography, chemical engineering, and other fields. At the same time, it can be used to prepare downstream fluorine chemical intermediates
Fluororesins (PTFE, PFA, FEP, PVDF, ETFE, etc.) are chemically resistant, weather resistant, and have low friction, but they have problems such as thermal decomposition toxicity, creep, and narrow processing windows. There are clear requirements for selection, processing, working conditions, storage, and disposal.
Calcium bromide is an inorganic bromide salt that is highly deliquescent. It is available in anhydrous, dihydrate, and 52% liquid form. Its core characteristics include high-density aqueous solution, low freezing point, bromide ion source, and strong hygroscopicity. It is widely used in oil and gas chemical industry, chemical industry, refrigeration, environmental protection, material synthesis, a
Potassium hydrogen fluoride can stably release hydrogen fluoride and has the functions of fluorine source, acidic chelating agent, and melting aid. It belongs to Class 8 corrosive hazardous chemicals and is widely used in fluorine chemical industry, metal surface treatment, glass processing, electronic manufacturing, and organic synthesis.
Potassium fluorosilicate belongs to toxic fluorine-containing powders, which release corrosive and toxic smoke when exposed to acid and high temperature. The core of operation revolves around dust prevention, contact prevention, staying away from acid and high temperature, and standardized waste liquid disposal.
Sodium hydrogen fluoride is an acidic fluoride salt that can smoothly release fluoride ions and has the characteristics of acidic etching, complex rust removal, and melting aid; Compared to liquid hydrofluoric acid, solid form is more convenient for storage and transportation, and is widely used as an etchant, metal surface treatment agent, fluorine chemical intermediate, and welding melting aid r
