ʻO Benzyl chloride, i ʻike ʻia ʻo benzyl chloride a me toluene chloride, he wai kala ʻole me ka ʻala ʻala ikaika. Hiki ke hui pū me nā mea hoʻoheheʻe organik e like me ka chloroform, ethanol, a me ka etera. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia me ka mahu wai. He mea hoʻonāukiuki kona mahu i ka ʻāʻī o nā maka a he mea hoʻoheheʻe waimaka ikaika. I ka manawa like, ʻo ka benzyl chloride kekahi mea waena i ka synthesis organik a hoʻohana nui ʻia i ka synthesis o nā dyes, pesticides, synthetic fragrants, detergents, plasticizers, a me nā lāʻau lapaʻau.

Nui nā ʻano hana synthesis no ka benzyl chloride, ʻoi aku ka nui o ka benzyl alcohol chlorination method, chloromethyl method, toluene catalytic chlorination method, etc. I waena o lākou, loaʻa ke ʻano benzyl alcohol chlorination e ka hopena o ka benzyl alcohol a me ka waika hydrochloric. ʻO ia ke ʻano hana synthesis mua loa o ka benzyl chloride. ʻO ke ʻano chloromethyl kekahi ʻano hana hana mua. ʻO kāna mau mea maka he benzene a me benzaldehyde (a i ʻole trimerformaldehyde). Hoʻohana ʻia ka zinc chloride anhydrous ma ke ʻano he catalyst. ʻO ka catalytic chlorination o toluene i kēia manawa ke ʻano hana hana maʻamau o ka benzyl chloride, a hiki ke hoʻokaʻawale ʻia ka catalytic chlorination o toluene i ka photocatalytic chlorination a me ka haʻahaʻa haʻahaʻa catalytic chlorination. Eia nō naʻe, pono ke ʻano o ka photocatalytic chlorination i ka hoʻokomo ʻana i kahi kumu kukui i loko o nā mea hana, nona nā ʻano paʻakikī e kāohi i ka hopena, nui nā ʻaoʻao ʻaoʻao, a me ke kumukūʻai kiʻekiʻe. Hoʻohana ka haʻahaʻa haʻahaʻa catalytic chlorination i hoʻokahi a ʻoi aku paha o ka dibenzoyl peroxide, azobisisobutyronitrile, a me ka acetamide ma ke ʻano he catalyst e hana i ka toluene a me ka chlorine i ka haʻahaʻa haʻahaʻa, me ka hoʻohana ʻana i ka haʻahaʻa haʻahaʻa a me ka chlorine E hoʻomalu i ka wikiwiki o ka hopena e hoʻomaikaʻi i ka helu hoʻololi a me ka koho, akā nā kūlana kikoʻī. pono e makaikai.

Lawe ʻia ka mahana distillation o benzyl chloride ma 100°C a ʻaʻole pono e ʻoi aku ma mua o 170°C. ʻO kēia no ka mea he mea wela ka benzyl chloride. Inā kiʻekiʻe loa ka mahana, e hana ʻia kahi hopena polymerization ponoʻī. Inā ʻoi aku ka ikaika o ka hopena, e loaʻa ana ka pōʻino Pahū. No laila, pono e hana ʻia ka distillation o ka crude benzyl chloride ma lalo o ke kaomi ʻino. I ka manawa like, pono e hoʻomalu i ka ʻona ion metala i loko o ka hopena chlorination, no ka mea, e loaʻa ana ka benzyl chloride i kahi hopena Krafts-Kreider i ke alo o nā ion metala a me ka wela kiʻekiʻe, a e hoʻokumu ʻia kahi mea resinous, ka mea e hana ai. ka wai i ʻO ka waihoʻoluʻu ʻeleʻele a hoʻokuʻu ʻia ka nui o ke kinoea hydrogen chloride.

ʻO Benzyl chloride kahi mea koʻikoʻi koʻikoʻi. ʻO ka huahana ʻoihana he wai aniani ʻole a ʻulaʻula melemele me kahi ʻala ʻala a me ka corrosive ikaika. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ether, chloroform, a me chlorobenzene. Hoʻohana nui ʻia ka Benzyl chloride i ka ʻoihana. Hoʻohana nui ʻia ia ma nā ʻano pesticides, nā lāʻau lapaʻau, nā mea ʻala, nā mea kōkua dye, a me nā mea kōkua synthetic. Hoʻohana ʻia ia e hoʻomohala a hana i benzaldehyde, butyl benzyl phthalate, aniline, phoxim, a me benzyl chloride. Penicillin, benzyl alcohol, phenylacetonitrile, phenylacetic acid a me nā huahana ʻē aʻe.

Aia ka Benzyl chloride i ka papa benzyl halide o nā mea hoʻonāukiuki. I ka ʻōlelo o nā pesticides, ʻaʻole hiki ke hoʻopili pololei i ka organophosphorus fungicides rice blast net a me iso rice blast net, akā hiki ke hoʻohana ʻia i mea waiwai nui no nā mea waena ʻē aʻe, e like me ka synthesis o phenylacetonitrile a me benzene. Formyl chloride, m-phenoxybenzaldehyde, etc. Eia kekahi, hoʻohana nui ʻia ka benzyl chloride i ka lāʻau lapaʻau, nā mea ʻala, nā mea kōkua dye, resins synthetic, a me nā mea ʻē aʻe. A laila ʻo ka wai ʻōpala a i ʻole ka ʻōpala i hana ʻia e nā ʻoihana i ka wā o ke kaʻina hana i hiki ke loaʻa ka nui o nā benzyl chloride intermediates.

ʻO Benzyl chloride ponoʻī ka waimaka, ʻona loa, carcinogenic, a hoʻomau i ke kaiapuni. No ka mea, hoʻohana nui ʻia ka benzyl chloride ponoʻī a hoʻohana ʻia i ka nui, ua kahe ka benzyl chloride i ka wā o ka lawe ʻana a i hana ʻia e nā mea hana like ʻole. ʻO ka wai ʻōpala i loaʻa i ka benzyl chloride i lawe ʻia e ka ʻoihana i ka wā o ke kaʻina hana a i ʻole ka ʻōpala i hoʻolei pololei ʻia, a i ʻole ka leakage i ka wā o ke kaʻina hana, e hoʻokomo pololei i ka benzyl chloride i ka lepo a hoʻohaumia i ka lepo.
