| 摘 要： | 以苯为溶剂,采用马来酸酐与3-巯基丙酸合成得到羧乙基硫代丁二酸(CESTA)。当反应时间为7 h、反应温度为85℃、n(马来酸酐)∶n(3-巯基丙酸)为1∶1.1时,CESTA收率高达98.8%。测定了CESTA钙螯合值为3 119 mg/g,并采用鼓泡法测定了其阻垢性能。当CESTA质量浓度为10 mg/L时,阻垢率达99%以上。

| Abstract: | Benzene being used as solven t,Carboxyethylth iosuccinic acid(CESTA) has been synthesized by the reaction of maleic anhydride with 3-mercaptopropionic acid.When the reaction time is 7 h,reaction temperature is 85 ℃,n(maleic anhydride) ∶n(3-mercaptopropionic acid)=1∶1.1,the yield of CESTA is as high as 98.8%.The calcium chelating capacity of carboxyethylthiosuccinic acid is 3 119 mg/g.The scale inhibition capacity is determined by bubbling method.The inhibiting rate of carboxyethylthiosuccinic acid as scale inhibitor is more than 99%,when the concentration of CESTA is more than 10 mg/L. |
