| 6. | The other conjugation polymer was formed by copolymerization of n - ( a - naphthyl ) carbazole with l , 4 - di ( chloromethyl ) benzene . the third organic molecule was synthesized by heck reaction with 9 , 9 - di [ ( 4 - iodine ) phenyl ] fluorene and vinylcarbazole 一个共轭高聚物为n - ( -萘基)咔唑和对二氯甲基苯通过wittig - horner反应聚合得到的高分子化合物。 |
| 7. | Considered its terminating effect on interfacial polymerization reaction , the quantity of 4 - ( chloromethyl ) benzoyl chloride should be limited to some extent . for the ip process investigated , n - dodecane and water can be used as solvents for dabsa and tmc solutions , respectively 在界面聚合过程中,分别以正十二烷和水作为有机相和无机相单体的溶剂,以十二烷基硫酸钠( sds )作为表面活性剂。 |
| 8. | For this purpose , 2 , 5 - diaminobenzene sulphonic acid ( dabsa ) [ c6h3 ( nh2 ) 2so3h ] can be selected as one monomer of ip reaction . the other monomer can be trimesoyl chloride ( tmc ) [ c6h3 ( coc1 ) 3 ] . in order to introduce the cationic group into membrane , 4 - ( chloromethyl ) benzoyl chloride ( cmbc ) [ ch2c1c6h4 ( coc1 ) ] could be added into organic phase ( tmc ) and used for chemical modification after ip process based on the reaction between 4 - ( chloromethyl ) benzoyl chloride and trimethylamine ( tma ) 为了引入阳离子交换基团,本文采用2 , 5 -二胺基苯磺酸作为界面聚合的无机相单体;为了引入阴离子交换基团,在均苯三甲酰氯有机相单体中加入一定量的4 -氯甲基苯酰氯,并考虑在无机相中加入适量的聚乙烯亚胺( pei )以增加其正荷电性。 |
| 9. | Purified yntatl trypanosomes were broken by n - tosyl - lysine chloromethyl ketone ( tlck ) and centrifugated by high g to form soluble proteins . the soluble proteins were chromatographed on a de - 52 column . the material in the first peak constituted the purified vsg 用国际命名法命名为yntat1 . 1 、 yntat1 . 2 、 - - - yntat1 . 20 ,从实验结果中未见这20个vats在5只兔体内按照某种特定规律变异,但是其中有15个优势vats在连续感染中多次重复,这印证了某些vats倾向于在感染早期出现的规律( gray1965等) 。 |
