摘要
用大口径毛细管气相色谱法对甲基丙烯酸特种酯合成反应液中的各组分进行了分离分析鉴定。色谱柱 :高惰性交联SE 5 4大口径石英弹性毛细管柱 ,5 0m× 0 5 3mmi d × 0 6 μm。主组分回收率为 99 71%～ 10 2 89%,相对标准偏差小于 0 1%。
A simple, rapid and accurate method for separating and analysing components in the synthesis of special esters of methacrylic acid by gas chromatography is reported An SE 54 wide bore capillary column of 50 m ×0 53 mm i.d.×0 6 μm was used The esters include dimethylaminoethyl methacrylate(DMAM), n butyl methacrylate(BMA) and ethylene glycol dimethacrylate(EGDMA). Crude materials such as methyl methacrylate(MMA) and N,N dimethyl ethanol amine (DMEA) were also analysed The recoveries were 99 71% 102 89%, and the RSDs of the main components were below 0 1% The method can be used to control the production of the esters
