摘要
以溴代癸烷、二苯醚和氯磺酸为原料合成癸烷基二苯醚双磺酸钠。考察了合成过程中的烷基化和磺化反应的工艺条件。结果表明,烷基化的较佳反应条件是:n(二苯醚)︰n(溴代癸烷)为1︰1,n(二苯醚):n(催化剂)=4︰1,反应温度为75℃,反应时间5h,烷基化的产率达87.62%;磺化反应的较佳反应条件是:n(烷基二苯醚):n(氯磺酸)=1:4,反应温度为15℃,反应时间20min,磺酸基的数目为1.91。
The sodium decyldiphenylether disulfonate was synthesized by diphenyl ether, bromodecane and chloric sulfoacid. The synthetic conditions of alkylation and sulfonation were investigated. Alkylation was carried out with n(diphenyl ether) : n(bromodecane)=1 : 1 and n(diphenyl ether) : n(catalysis) 4 : 1 at 75℃ for 5 h to attain 87.62 % yield. Sulfonation with n(alkylated diphenyl ether) : n(chloric sulfoacid)=l : 4 was carried out at 15℃ for 20 rain, and the number of sulfonic acid group per molecule was 1.91.
