Photopolymerized 大音阶的第五音胶化(PSG ) 列作为单体用 methacryloxypropyltrimethoxysilane 被准备,甲苯作为 porogen 和盐酸作为催化剂。象安息香甲基醚, Irgacure 819, Irgacure 1700 和 Irgacure 1800 那样的四个不同相片开始者比较地当面在反应答案被使用并且钠十二烷基硫酸盐的缺席。上述八个解决方案分别地在各个为 5 10 min 在 365 nm 被照耀毛状(在直径内的 75 μm ) 在 situ,处理由一出一步舞准备多孔的整体的大音阶的第五音胶化列。八 PSG 列的色析法的行为比较地被学习,所有哪个展览反向阶段的特性。用这些列,几中立混合物,也就是, thiourea,苯,甲苯,乙基苯,联本基和萘能为 thiourea 用 74 470 板 / 列的最大的列效率从混合物被分开。在聚合过程的钠十二烷基硫酸盐的增加在形态学和迁居时间上有重要影响。
Photopolymerized sol-gel(PSG) columns were prepared using methacryloxypropyltrimethoxysilane as the monomer, toluene as the porogen and hydrochloric acid as the catalyst. Four different photoinitiators such as benzoin methyl ether, Irgacure 819, Irgacure 1700 and Irgacure 1800 were comparatively used in the reaction solution in the presence and absence of sodium dodecyl sulfate. The above eight solutions were respectively irradiated at 365 nm for 5 10 min in each capillary (75 μm inside diameter) to prepare the porous monolithic sol-gel column by a one-step, in situ, process. The chromatographic behavior of the eight PSG columns were comparatively studied, all of which exhibit reversed-phase character. Using these columns, several neutral compounds, namely thiourea, benzene, toluene, ethyl benzene, biphenyl and naphthalene can be separated from mixtures with a largest column efficiency of 74 470 plate/column for thiourea. Addition of sodium dodecyl sulfate in the polymerization process has a significant influence on the morphology and migration time.
