摘要
合成了两种季鳞盐产物硫酸四羟甲基鳞(THPS)和氯化四羟甲基鳞(THPC),进行了元素分析,并用红外光谱和31P-核磁共振进行了结构鉴定。建立了测定其活性物含量的离子交换法,测得二者的含量为w(THPS)76.05%,w(THPC)75.84%。对产物的杀菌效能进行了评定,结果表明:当THPS和THPC的质量浓度均为50mg/L时,对硫酸盐还原菌的杀菌率为100%;当THPS和THPC的质量浓度均为100mg/L时,对异养菌的杀菌率为99.6%。
Two kinds of quaternary phosphonium salts - tetrakis-(hydroxymethyl) phosphonium sul-fate (THPS) and tetrakis-(hydroxymethyl) phosphonium chloride (THPC) were synthesized, and their structures were identified by elementary analysis, IR and 31P NMR. For determination of the active matter contents in the products, a new method by ion-exchange technique was established, the results of w(THPS) and w(THPC) are 76. 05% and 75. 84% respectively. The bactericidal potencies of the products were evaluated, the results showed that when the concentrations of THPS and THPC are 50 mg/L, the bactericidal efficiency on SRB are all 100%, and when the concentrations of THPS and THPC are 100 mg/L, the bactericidal efficiency on HB are all 99. 6%.
