摘要

合成了五种含有苄氨基结构的有机硅单体:XCH2--CH2 CH2Si(OCH3)3(X=-NH(CH2)2CH3、-NH(CH2)3CH3、-N(C2H5)2、-NH(CH2)2NH2和-NH2).红外光谱、核磁共振及硅元素分析证实了所合成的单体具有预期的化学结构.通过硅官能团的反应

这些单体可以固定在气相二氧化硅表面而制成载有苄氨基结构的二氧化硅.固定化产物的漫反射红外光谱证实了这点.同时

对水溶液中微量Cu2+吸附的结果表明

固定化产物对Cu2+的捕集均有一定效果而以X=-NH(CH2)2CH3及-NH(CH2)2NH2的为最佳.

Abstract

Five members of a novel family of silane coupling agents containing amine-lig-ands

X-CH

--CH2CH2 Si(OCH3)3 [X=-NH2

-NH(CH2)2CH3) -NH(CH2)3CH3

-N(C2H5)2

and -NH(CH2)2NH2]

were synthesized by the amination reaction of β-(p-chloromethylphenyl) ethyltrimethoxysilane with corresponding ami. nes. The structure of the coupling agents was characterized and confirmed by FT-IR

'H-NMR spectrometry and elementary analysis. The organosilanes could be easily immobilized onto the surface of silica fume and due to thepresence of the anchored amine-ligands the silanized silica fume showed in varying degrees the abi-lity to catch Cu2+ from its aqueous solution.
