| Abstract: | Sodium methylparaben, a derivant of methylparaben, is a new type of muhifunctional and high performance food or cometic additive. The preparation of sodium methylparaben by methylparaben and sodium hydroxide as raw materials was studied. The main factors affecting the quality of product were determined by experiments. The optimal reaction conditions for the synthesis of sodium methylparaben were obtained by studying the influence of reagent ration, reaction temperature and methods of feeding materials. The final purity of products reached 99.5% which meeted the pharmacopoeia standards. |
