烷基卤

In order to investigate the quantitative structure-retention relationship in gas chromatography, the molecular structure of monosubstituted alkane RX (X=halogen, OH, SH, NH2) is divided into two parts, R and X, to obtain molecular structure parameters, and the retention times in GC for 37 monosubstituted alkanes RX were determined.

将单取代烷烃RX(X=卤素，OH，SH，NH2等)分子结构分为两个区域来提取分子结构参数，从三方面影响因素(烷基R、取代基X、R与X的相互作用)来定量关联RX的气相色谱保留时间。

Organic our country high polymer flocculant already has commercialized at present having several breeds such as PAM , polypropylene acidamides and carboxyl methyl cellulose only , studies innocuous high-effect organic synthesis high polymer flocculant (the ammonium equality gathers the sum copolymer kind if alkyl alkene propyl group halogenates waiting), optimizes it's the cost reduction composing handicraft.
