Benzeneacetonitrile (CAS # 140-29-4)
Benzeneacetonitrile, CAS NO.
Los ntawm cov qauv tshuaj, nws yog tsim los ntawm ib lub nplhaib benzene txuas mus rau ib pawg acetonitrile. Lub nplhaib benzene muaj ib tug loj π daim ntawv cog lus conjugation system, uas muab lub molecule stability thiab ib tug tshwj xeeb electron huab faib, uas ua rau nws muaj ib tug tej yam aromaticity. Cov pab pawg acetonitrile qhia txog qhov muaj zog polarity thiab reactivity ntawm pawg cyano, uas ua rau tag nrho cov molecule tsis tsuas yog muaj cov txheeb ze inertness thiab hydrophobicity coj los ntawm benzene nplhaib, tab sis kuj muab nplua nuj possibilities rau organic synthesis vim hais tias pawg neeg cyano tuaj yeem koom nrog ntau yam. ntawm nucleophilic thiab electrophilic cov tshuaj tiv thaiv. Nws feem ntau tshwm sim raws li cov xim tsis muaj xim rau lub teeb daj ua kua hauv qhov tsos, thiab daim ntawv ua kua no yooj yim rau kev hloov thiab ua kom huv los ntawm kev ua haujlwm niaj hnub xws li kev sib cais ua kua thiab distillation hauv chav kuaj thiab cov khoom sib xyaw ua ke. Nyob rau hauv cov nqe lus ntawm solubility, nws yuav ua tau zoo soluble nyob rau hauv cov organic solvents, xws li ether, chloroform thiab lwm yam uas tsis yog-polar los yog weakly polar solvents, thaum nyob rau hauv dej solubility yog tsis zoo, uas yog ze ze rau molecular polarity, thiab kuj txiav txim siab nws daim ntawv thov xaiv. nyob rau hauv cov tshuaj tiv thaiv sib txawv.
Nws yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis daim ntaub ntawv. Raws li lawv cov khoom tsim, ntau yam tshuaj tiv thaiv tuaj yeem tshwm sim los tsim cov tebchaw nyuaj. Piv txwv li, los ntawm cov tshuaj tiv thaiv hydrolysis ntawm cyanogroup, phenylacetic acid tuaj yeem npaj tau, uas yog siv rau hauv kev lag luam tshuaj los ua ke ntau yam tshuaj, xws li kev hloov pauv ntawm cov tshuaj tua kab mob penicillin; Hauv kev lag luam txuj lom, nws yog cov khoom siv tseem ceeb rau kev npaj cov txuj lom floral xws li roses thiab lily ntawm hav. Tsis tas li ntawd, kev txo cov tshuaj tiv thaiv ntawm cyano kuj tseem siv tau los hloov nws mus rau hauv benzylamine compounds, thiab benzylamine derivatives yog siv dav hauv kev siv tshuaj tua kab thiab dyes, thiab siv los tsim cov tshuaj tua kab tshiab, dyes nrog cov xim ci thiab siab. ceev ceev.
Hais txog kev npaj, acetophenone feem ntau yog siv los ua raw khoom hauv kev lag luam, thiab nws yog npaj los ntawm ob-kauj ruam cov tshuaj tiv thaiv ntawm oxime thiab lub cev qhuav dej. Ua ntej, acetophenone reacts nrog hydroxylamine los tsim acetophenone oxime, uas tom qab ntawd hloov mus rau Benzeneacetonitrile nyob rau hauv qhov kev txiav txim ntawm lub dehydrator, thiab nyob rau hauv cov txheej txheem, cov kws tshawb fawb txuas ntxiv optimize cov tshuaj tiv thaiv tej yam kev mob, nrog rau kev kho cov tshuaj tiv thaiv kub thiab tswj tus nqi ntawm lub dehydrator, yog li ntawd. raws li kev txhim kho cov qoob loo, txo tus nqi, thiab xyuas kom meej qhov kev thov rau cov khoom loj. Nrog rau innovation ntawm organic synthesis technology, qhov optimization ntawm txoj kev synthesis ntawm Benzeneacetonitrile tsom rau kev tiv thaiv ib puag ncig thiab atomic kev lag luam, siv zog los txo cov emissions pov tseg, txhim kho kev siv cov peev txheej efficiency, pab txhawb kev txhim kho kev lag luam tshuaj lom neeg, thiab ntxiv rau nws daim ntawv thov. peev xwm.
