Khoom npe: Benzyl chloride

Lub npe Askiv: Benzyl chloride

CAS Nr .: 100-44-7

Benzyl chloride, tseem hu ua benzyl chloride thiab toluene chloride, yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw muaj zog. Nws yog miscible nrog cov kuab tshuaj organic xws li chloroform, ethanol, thiab ether. Nws yog insoluble hauv dej tab sis tuaj yeem evaporate nrog dej vapor. Nws cov ncu yog irritating mus rau mucous daim nyias nyias ntawm ob lub qhov muag thiab yog ib tug muaj zog tsim kua muag-triggering neeg sawv cev. Nyob rau tib lub sijhawm, benzyl chloride kuj yog ib qho nruab nrab ntawm cov organic synthesis thiab yog dav siv nyob rau hauv cov synthesis ntawm dyes, tshuaj tua kab, hluavtaws fragrances, detergents, plasticizers, thiab tshuaj.

Muaj ntau ntau txoj kev sib txuas rau benzyl chloride, feem ntau suav nrog benzyl cawv chlorination txoj kev, chloromethyl txoj kev, toluene catalytic chlorination txoj kev, thiab lwm yam. Nws yog cov txheej txheem synthesis ntxov tshaj plaws ntawm benzyl chloride. Txoj kev chloromethyl kuj yog ib qho kev lag luam thaum ntxov. Nws cov ntaub ntawv raw yog benzene thiab benzaldehyde (los yog trimerformaldehyde). Anhydrous zinc chloride yog siv los ua catalyst. Lub catalytic chlorination ntawm toluene tam sim no yog cov kev lag luam ntau tshaj plaws ntawm benzyl chloride, thiab catalytic chlorination ntawm toluene tuaj yeem muab faib ua photocatalytic chlorination thiab low-temperature catalytic chlorination. Txawm li cas los xij, cov txheej txheem photocatalytic chlorination yuav tsum tau teeb tsa lub teeb pom kev hauv cov khoom siv, uas muaj cov yam ntxwv ntawm kev nyuaj rau kev tswj cov tshuaj tiv thaiv, ntau qhov kev cuam tshuam sab nraud, thiab tus nqi siab. Txoj kev ntsuas kub qis catalytic chlorination siv ib lossis ntau dua ntawm dibenzoyl peroxide, azobisisobutyronitrile, thiab acetamide ua cov tshuaj tiv thaiv toluene thiab chlorine ntawm qhov kub thiab txias, siv qhov kub thiab txias thiab tshuaj chlorine Tswj cov tshuaj tiv thaiv los txhim kho tus nqi hloov pauv thiab xaiv, tab sis cov xwm txheej tshwj xeeb. tseem yuav tau tshawb nrhiav.

Qhov kub distillation ntawm benzyl chloride feem ntau ua tiav ntawm 100 ° C thiab feem ntau yuav tsum tsis pub tshaj 170 ° C. Qhov no yog vim hais tias benzyl chloride yog ib yam khoom kub-rhiab heev. Yog tias qhov kub thiab txias dhau lawm, cov tshuaj tiv thaiv tus kheej-polymerization yuav tshwm sim. Yog tias qhov kev tawm tsam hnyav dhau, yuav muaj kev phom sij tawg. Yog li ntawd, lub distillation ntawm crude benzyl chloride yuav tsum tau nqa tawm nyob rau hauv tsis zoo siab. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los tswj cov hlau ion cov ntsiab lus hauv cov tshuaj chlorination, vim tias benzyl chloride yuav dhau los ntawm Krafts-Kreider cov tshuaj tiv thaiv nyob rau hauv muaj cov hlau ions thiab kub, thiab cov tshuaj resinous yuav raug tsim, uas yuav ua rau muaj kev cuam tshuam ntawm cov hlau ions. cov kua rau Cov xim yuav tsaus thiab ntau cov pa roj hydrogen chloride tso tawm.

Daim ntawv thov

Benzyl chloride yog ib qho tseem ceeb ntawm cov organic nruab nrab. Cov khoom lag luam yog cov xim tsis muaj xim lossis lub teeb daj pob tshab nrog cov ntxhiab tsw thiab muaj zog corrosiveness. Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li ether, chloroform, thiab chlorobenzene. Benzyl chloride yog siv dav hauv kev lag luam. Nws yog tsuas yog siv nyob rau hauv cov teb ntawm tshuaj tua kab, tshuaj, txuj lom, zas auxiliaries, thiab hluavtaws auxiliaries. Nws yog siv los tsim thiab tsim benzaldehyde, butyl benzyl phthalate, aniline, phoxim, thiab benzyl chloride. Penicillin, benzyl cawv, phenylacetonitrile, phenylacetic acid thiab lwm yam khoom.

Benzyl chloride belongs rau benzyl halide chav kawm ntawm cov tshuaj tiv thaiv kab mob. Nyob rau hauv cov nqe lus ntawm cov tshuaj tua kab, nws muaj peev xwm tsis tsuas yog ncaj qha synthesize lub organophosphorus fungicides nplej blast net thiab iso nplej blast net, tab sis kuj yuav siv tau raws li ib tug tseem ceeb raw khoom rau ntau lwm yam intermediates, xws li cov synthesis ntawm phenylacetonitrile thiab benzene. Formyl chloride, m-phenoxybenzaldehyde, thiab lwm yam. Tsis tas li ntawd, benzyl chloride yog dav siv nyob rau hauv cov tshuaj, spices, dye auxiliaries, hluavtaws resins, thiab lwm yam. Nws yog ib qho tseem ceeb tshuaj thiab tshuaj ntau lawm intermediate. Tom qab ntawd cov dej khib nyiab los yog cov khoom pov tseg uas tsim los ntawm cov lag luam thaum lub sij hawm tsim cov txheej txheem inevitably muaj ib tug loj npaum li cas ntawm benzyl chloride intermediates.

Benzyl chloride nws tus kheej yog tsim kua muag, muaj kuab heev, carcinogenic, thiab ib puag ncig tsis tu ncua. Txij li thaum benzyl chloride nws tus kheej tau siv dav thiab siv ntau ntau, benzyl chloride leaks thaum thauj los yog tsim los ntawm ntau lub tuam txhab. Cov kua khib nyiab uas muaj benzyl chloride coj los ntawm lub tuam txhab thaum lub sijhawm tsim khoom lossis cov khoom pov tseg raug muab pov tseg ncaj qha, lossis cov dej xau tshwm sim thaum lub sijhawm tsim khoom, uas yuav ncaj qha ua rau benzyl chloride nkag mus rau hauv av thiab nws thiaj li ua paug rau cov av.
