| titleOfInvention | Synthetic method of fatty alkyl dimethyl benzyl quaternary ammonium salt |
| abstract | The invention discloses a preparation method of fatty alkyl dimethyl benzyl quaternary ammonium salt. The preparation method of the fatty alkyl dimethyl benzyl quaternary ammonium salt comprises the following steps of carrying out salt forming reaction on fatty alkyl dimethyl tertiary amine and benzyl halide in an organic solvent at the temperature of 30-70 ℃; wherein in the fatty alkyl tertiary amine, R is C 6 H 13 ～C 22 H 45 (ii) a In the benzyl halide, the halogen is chlorine, bromine or iodine; the organic solvent is one or more of methanol, ethanol, n-propanol, isopropanol, acetone and acetonitrile. The preparation method has high yield which can reach more than 90 percent; high purity (up to more than 99%), low water content, good appearance and form of the product, simple post-treatment, low energy consumption, and suitability for industrial production. |
