Fatty alkyl dimethyl benzyl quaternary ammonium salt synthesis method

The invention discloses a fatty alkyl dimethyl benzyl quaternary ammonium salt preparation method, which comprises: carrying out a salt formation reaction on fatty alkyl dimethyl tertiary amine and abenzyl halide in an organic solvent at a temperature of 30-70 DEG C, wherein R in the fatty alkyl tertiary amine is C6H13-C22H45, the halogen in the benzyl halide is chlorine, bromine or iodine, and the organic solvent is one or a plurality of materials selected from methanol, ethanol, n-propanol, isopropanol, acetone and acetonitrile. According to the present invention, the yield of the preparation method is high, and can reach more than 90%; the purity is high, and can achieve more than 99%; the water content is low; the product has good appearance and simple post-treatment effect; and the method can reduce the energy consumption, and is suitable for industrial production.

Preparation of benzalkonium salts differing in the length of a side alkyl Chain

Benzalkonium salts are widely used as disinfectants, biocides and detergents, among a variety of other applications. The cationic surface-activity of these salts determines their potential to act as a biocide on both target and non-target organisms. In this study, a quick synthesis of a complete set of the benzalkonium salts differing in the length of an alkylating chain (from C2 to C20) is described. Moreover, their 1H-NMR, HPLC-MS, TLC and HPLC analysis were recorded.
