摘要:
用醋酸乙烯酯( VA c)与端羟基聚二甲基硅氧烷( hydroxy-term inated PDM S 或OH-term in ated PDMS ) 反应得到 PDMS-VAc接枝共聚物. 以此共聚物为固定液用溶胶凝胶法制成毛细管气相色谱柱. 此色谱柱的分离性能力较强, 不仅对于烷烃类和芳烃类等化合物达到有效的分离, 而且对酚类和胺类等较难分离的化合物也有令人满意的分离效果. 更值得一提的是该柱对各类有机物的混合物的分离也相当出色. 测定结果表明该色谱柱对各类化合物, 特别是对极性化合物的惰性良好, 不对称因子(A )的测定结果均为1. 柱效率较高, 理论塔板数达到2 940 /m. 该柱且具有良好的稳定性, 各类化合物保留时间10次测定的相对标准偏差不超过0. 30%. 麦氏常数总和测定值为464, 表明此固定相已达中等极性.
Abstract:
PDMS- VAc is obta ined from the reac tion be tw een VA c and hydroxy-term ina ted po ly-d im ethy lsilox ane ( or OH-term inated PDMS). It is used as stationary phase tom ake cap illary co lumn for gas chrom atography by using so lg elm e thod. The co lum n has a strong sepa rative pow er, and can no t on ly effic iently separa te a lky l com pounds and aro m atic com pounds, but also satisfacto rily separate such com pounds as hydroxybenzenes and am ines wh ich are d ifficu lt to separate. W hat is mo re, the co lumn can separate var ious o rganic com pounds quite w e l.l The testing resu lts show that the column has a good inertia fo r var ious o rganic com pounds and espec ia lly po lar com pounds. The testing resu lt of unsymm etr ic gene ( A) is 1. This co lum n a lso show s good co lumn efficiency, satisfacto ry stab ility and fine symm e- try of the peaks. The testing resu lt of the sum o fM cReynold s’ constants is 464, w hich shows that the po la rity o f the new sta tionary phase is stronger than that of PDMS, reaches the m iddling po larity.
