What are quaternary ammonium salts used for? Quaternary ammonium salts, also known as quaternary ammonium salts, English name Quaternary Ammonium Salt, are compounds generated by the substitution of four hydrogen atoms in ammonium ions by hydrocarbon groups. The general formula is R4NX, and the four hydrocarbon groups R can be the same or different. Quaternary ammonium salts are similar in nature to inorganic salts, easily soluble in water, and aqueous solutions can conduct electricity. Mainly prepared by the reaction of ammonia or amine with haloalkanes.
When X in the quaternary ammonium salt molecule is OH, it is often called a quaternary ammonium base. Quaternary ammonium bases are strong bases and are similar in alkalinity to sodium hydroxide and potassium hydroxide. The World Health Organization, the National Cancer Institute and the National Toxic Administration have determined that exposure to formaldehyde may be associated with the etiology of leukemia. Reports show that quaternary ammonium salts-15 and formaldehyde are potential potent allergens, which can cause skin inflammation such as rashes.
Quaternary ammonium salts have a wide range of uses and can be used as agricultural fungicides, sterilization and disinfection in public places, circulating water sterilization and algaecide, aquaculture sterilization and disinfectant, medical sterilization and disinfectant, livestock and poultry house disinfectant, red tide disinfectant, cyanobacteria disinfectant and other sterilization and disinfection fields. In particular, Gemini quaternary ammonium salt has outstanding sterilization effect and low comprehensive cost. It can also be used in the textile printing and dyeing industry. Such softeners have excellent softness, antistatic, sterilization and yellowing resistance. Less dosage, good effect, convenient preparation, good compatibility, and high cost performance.
