benzyl

A kind of chiral azo molecule derived from amino acid , n - [ 4 - ( 4 - dodecyloxyphenylazo ) benzoyl ] - l - glutamic acid ( c12 - azo - l - glu ) , was investigated . the photochromism , photoinduced birefringence , and holographic recording in c12 - azo - l - glu doped poly ( methyl methacrylate ) ( pmma ) films were studied . c12 - azo - l - glu underwent a reversible tram - cis - trans isomerization in the polymer matrix 我們利用手性偶氮苯染料c _ ( 12 ) - azo - l - glu摻雜聚甲基丙稀酸甲脂( pmma )薄膜為實驗樣品,對其光致變色過程,光致雙折射和全息存儲特性進行了研究分析。

According to the purity and the activity recovery , the recombinant enzyme was well purified by both of these two separation combinations . like natural gloshedobin , the recombinant enzyme exhibited strong esterase activity using tripeptide p - nitroanilide derivatives as substrate , but hydrolyzed n a - p - tosyl - l - arginine methyl ester ( tame ) or n a - benzoyl - l - arginine ethyl ester ( baee ) very weakly 與天然蛇毒類凝血酶一致,當用三肽p山itroanilide衍生物作為底物時,分泌表達的重組大連蛇島蝗蛇毒類凝血酶具有較強的生色底物活性,但用精氨酸甲酯如tame ( na廠tosyl l ar 。

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 ) 為了引入陽離子交換基團,本文采用2 , 5 -二胺基苯磺酸作為界面聚合的無機相單體;為了引入陰離子交換基團,在均苯三甲酰氯有機相單體中加入一定量的4 -氯甲基苯酰氯,并考慮在無機相中加入適量的聚乙烯亞胺( pei )以增加其正荷電性。

Abstract : cetirizine hydrochloride was synthesized from chlorobenzene and benzoyl chloride by the friedel - crafts reaction , reduction , and chlorination followed by condensation with piperizine , 2 - chloroethanol and sodium chloroacetate in turn in 28 . 2 % overall yield based on chlorobenzene 文摘:以氯苯和苯甲酰氯為起始原料,經付克反應、還原、氯化,再分別與哌嗪、氯乙醇、氯乙酸鈉縮合,成鹽制得鹽酸西替利嗪,總收率為28 . 2 %

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 在界面聚合過程中,分別以正十二烷和水作為有機相和無機相單體的溶劑,以十二烷基硫酸鈉( sds )作為表面活性劑。

Acetylation between alcohol and benzoyl oxide was carried out using znbr2 as a lewis acid catalyst in solvent - free condition . some structures were characterized by nmr and ir 摘要以溴化鋅為催化劑,在無溶劑條件下實現了醇與苯甲酸酐的酰化反應,部分產物經nmr和ir表征。
