| Abstract: | Dioctyl dimethylammonium hydroxide is synthesized with dioctylamine as raw material, dimethyl sulfate as alkylating agent and calcium oxide as removing acid agent. The conversion of the dioctylamine is 100%.Diocty dimethyl quaternary ammonium salt is formed by using HC1 or HBr to neutralize diocty Dimethyl ammonium hydroxide. This reaction time is short, the reaction product prodult rate is high, which is general 98.2% ,and product is quite pure. |
