tsananguro yechigadzirwa

Zita rechigadzirwa: Benzyl chloride

Zita rechiRungu: Benzyl chloride

Nhamba yeCAS 100-44-7

Benzyl chloride, inozivikanwawo se benzyl chloride ne toluene chloride, imvura isina ruvara ine hwema hwakasimba. Inosanganiswa nezvinhu zvinonyungudutsa zvakaita se chloroform, ethanol, ne ether. Hainyungudike mumvura asi inogona kupwa nemhepo ine utsi hwemvura. Utsi hwayo hunotsamwisa mumaziso uye isimba guru rinokonzera misodzi. Panguva imwe chete, benzyl chloride imhando yepakati mukugadzirwa kwe organic uye inoshandiswa zvakanyanya mukugadzirwa kwedhayi, mishonga yekuuraya zvipembenene, kunhuhwirira kwekugadzira, sipo, mapurasitiki, nemishonga.

Kune nzira dzakawanda dzekugadzira benzyl chloride, dzinosanganisira nzira yebenzyl alcohol chlorination, nzira yechloromethyl, nzira yetoluene catalytic chlorination, nezvimwewo. Pakati padzo, nzira yebenzyl alcohol chlorination inowanikwa nekuita kwebenzyl alcohol nehydrochloric acid. Ndiyo nzira yekutanga yekugadzira benzyl chloride. Nzira yechloromethyl zvakare inzira yekutanga yeindasitiri. Zvinhu zvayo zvekugadzira ibenzene nebenzaldehyde (kana trimerformaldehyde). Anhydrous zinc chloride inoshandiswa se catalyst. Catalytic chlorination ye toluene pari zvino ndiyo nzira yakajairika yekugadzira benzyl chloride mumaindasitiri, uye catalytic chlorination ye toluene inogona kukamurwa kuita photocatalytic chlorination uye low-temperature catalytic chlorination. Zvisinei, nzira ye photocatalytic chlorination inoda kuiswa kwechiedza mukati memidziyo, ine hunhu hwekuti yakaoma kudzora reaction, side reactions dzakawanda, uye mutengo wakakwira. Nzira yekubvisa chlorination inodziya zvishoma inoshandisa imwe kana kupfuura yedibenzoyl peroxide, azobisisobutyronitrile, uye acetamide senzira yekubatsira kugadzirisa toluene nechlorine pakupisa kwakaderera, uchishandisa tembiricha yakaderera uye chlorine. Dzora chiyero chemhinduro kuti uvandudze chiyero chekushandura uye kusarudza, asi mamiriro chaiwo achiri kuda kuongororwa.

Tembiricha yekudistilla yebenzyl chloride inowanzoitwa pa100°C uye kazhinji haifanirwe kudarika 170°C. Izvi zvinodaro nekuti benzyl chloride chinhu chinonzwa kupisa. Kana tembiricha yakanyanya, mhinduro yekuzvigadzirisa pachayo ichaitika. Kana mhinduro yacho yakanyanya, pachava nenjodzi yekuputika. Nokudaro, distilla yebenzyl chloride isina kuchena inofanira kuitwa pasi pekumanikidzwa kwakashata. Panguva imwe chete, zvakakosha kudzora huwandu hwesimbi mumaion mu chlorination solution, nekuti benzyl chloride ichaitwa neKrafts-Kreider reaction pamberi pesimbi maion uye tembiricha yepamusoro, uye chinhu chine resin chichagadzirwa, izvo zvichaita kuti mvura isvibe uye huwandu hwakawanda hwehydrogen chloride gasi huburitswe.

Mashandisirwo

Benzyl chloride chinhu chakakosha che organic. Chigadzirwa chemumaindasitiri imvura isina ruvara kana yero yakajeka ine hwema hunopisa uye inoparadza zvakanyanya. Inogona kunyungudutswa muzvinhu zvinonyungudutsa organic zvakaita se ether, chloroform, uye chlorobenzene. Benzyl chloride inoshandiswa zvakanyanya mumaindasitiri. Inonyanya kushandiswa muminda yemishonga yezvipembenene, mishonga, zvinonhuwira, dhayi, uye zvigadzirwa zvekugadzira. Inoshandiswa kugadzira nekugadzira benzaldehyde, butyl benzyl phthalate, aniline, phoxim, uye benzyl chloride. Penicillin, benzyl alcohol, phenylacetonitrile, phenylacetic acid nezvimwe zvigadzirwa.

Benzyl chloride iri muboka remakonzo anotsamwisa ebenzyl halide. Kana tichitaura nezvemishonga yezvipembenene, haingogone kugadzira zvakananga fungicides dze organophosphorus, rice blast net uye iso rice blast net, asiwo inogona kushandiswa sechinhu chakakosha kune zvimwe zvinhu zvepakati, zvakaita sekugadzirwa kwephenylacetonitrile nebenzene. Formyl chloride, m-phenoxybenzaldehyde, nezvimwewo. Pamusoro pezvo, benzyl chloride inoshandiswa zvakanyanya mukurapa, zvinonhuwira, madhayi, maresini ekugadzira, nezvimwewo. Inzvimbo yakakosha yekugadzira makemikari nemishonga. Zvadaro marara anogadzirwa nemabhizinesi panguva yekugadzira anova nehuwandu hwakawanda hwebenzyl chloride intermediates.

Benzyl chloride pachayo inokonzera kubvaruka, ine chepfu yakawanda, inokonzera kenza, uye inogara kwenguva refu munzvimbo dzakatikomberedza. Sezvo benzyl chloride pachayo ichishandiswa zvakanyanya uye ichishandiswa zvakanyanya, benzyl chloride inodonha panguva yekufambisa kana inogadzirwa nevagadziri vakasiyana-siyana. Marara ane benzyl chloride anounzwa nebhizinesi panguva yekugadzira kana marara anoraswa zvakananga, kana kuti kubuda kwemvura kunoitika panguva yekugadzira, izvo zvinozoita kuti benzyl chloride ipinde muvhu uye pakupedzisira inosvibisa ivhu.
