一种碳酸酯Gemini表面活性剂的合成及性能研究OA北大核心CSTPCD
Study on synthesis and properties of a novel Gemini surfactant with carbonate
合成了一种碳酸酯基Cemini表面活性剂C12H29(CH3)2N+CH2CH2OCO2CH2CH2N+-(CH3)2C12H29·2Br-(I).二(N,N-二甲基胺基乙基)碳酸酯(Ⅱ)与1-溴代十二烷反应,经乙腈重结晶后,得白色固体产物,收率为59.2%(以Ⅱ计).采用IR、1HNMR、元素分析表征了I的结构,两相滴定法分析其纯度为98.5%.电导法测定其CMC值为1.12×l0-3mol·L-1,滴体积法测定γCMC为38.59mN·m-1…查看全部>>
A Gemini surfactant with ester carbonate C12 H29 ( CH3 )2 N + CH2 CH2 OCO2 CH2 CH2 N + ( CH3 ) 2 -C12H29 · 2Bt( Ⅰ ) was synthesized. Bis[2- (dimethylamino)ethyl] carbonic ester ( Ⅱ )reacted with 1 -bromododecane, and the resulting quaternary salt was recrystallized in acetonitrile in the form of white solid with 59.2％ yield ( based on Ⅱ ). The structure was confirmed by IR, 1 HNMR and elemental analysis. The purity of I was 98.5％ by two - phase chemica…查看全部>>
