ʻO Benzyl chloride, i ʻike ʻia hoʻi ʻo benzyl chloride a me toluene chloride, he wai kala ʻole me kahi ʻala ʻawaʻawa ikaika. Hiki ke hui pū ʻia me nā mea hoʻoheheʻe organik e like me chloroform, ethanol, a me ether. ʻAʻole ia e hoʻoheheʻe ʻia i ka wai akā hiki ke mahu me ka mahu wai. Hoʻonāukiuki kona mahu i nā membrane mucous o nā maka a he mea hoʻoulu waimaka ikaika. I ka manawa like, ʻo benzyl chloride kekahi 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, ʻo ia hoʻi ke ʻano chlorination benzyl alcohol, ke ʻano chloromethyl, ke ʻano chlorination toluene catalytic, a pēlā aku. I waena o lākou, loaʻa ke ʻano chlorination benzyl alcohol ma o ka hopena o ka benzyl alcohol a me ka hydrochloric acid. ʻO ia ke ʻano synthesis mua loa o ka benzyl chloride. ʻO ke ʻano chloromethyl kekahi ʻano 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 ka ʻano hana hana ʻoihana maʻamau o ka benzyl chloride i kēia manawa, a hiki ke hoʻokaʻawale ʻia ka catalytic chlorination o toluene i ka photocatalytic chlorination a me ka haʻahaʻa-mahana catalytic chlorination. Eia nō naʻe, pono ke ʻano chlorination photocatalytic i ka hoʻokomo ʻana o kahi kumu kukui i loko o nā lako, nona nā ʻano o ka paʻakikī ke kāohi i ka hopena, nā hopena ʻaoʻao he nui, a me ke kumukūʻai kiʻekiʻe. ʻO ke ʻano hana chlorination catalytic haʻahaʻa haʻahaʻa e hoʻohana i hoʻokahi a ʻoi aku paha o dibenzoyl peroxide, azobisisobutyronitrile, a me ka acetamide ma ke ʻano he mea hoʻoulu e hana i ka toluene a me ka chlorine ma ka mahana haʻahaʻa, me ka hoʻohana ʻana i ka mahana haʻahaʻa a me ka chlorine E kāohi i ka helu o ka hopena e hoʻomaikaʻi i ka helu hoʻololi a me ke koho ʻana, akā pono e ʻimi ʻia nā kūlana kikoʻī.

ʻO ka mahana distillation o ka benzyl chloride ma ke ʻano maʻamau e hana ʻia 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 ka pōʻino pahū. No laila, pono e hana ʻia ka distillation o ka benzyl chloride maka ma lalo o ke kaomi maikaʻi ʻole. I ka manawa like, pono e kāohi i ka nui o ka ion metala i loko o ka hopena chlorination, no ka mea e hana ʻia ka benzyl chloride i kahi hopena Krafts-Kreider i ke alo o nā ion metala a me ka mahana kiʻekiʻe, a e hana ʻia kahi mea resinous, kahi e hoʻolilo ai i ka wai i ʻeleʻele ke kala a hoʻokuʻu ʻia ka nui o ke kinoea hydrogen chloride.

He mea koʻikoʻi ka Benzyl chloride i waena o nā mea olaola. He wai ʻālohilohi a melemele paha ka huahana ʻoihana me kahi ʻala ʻawaʻawa a me ka ikaika o ka ʻino. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe olaola e like me ka ether, chloroform, a me ka chlorobenzene. Hoʻohana nui ʻia ka Benzyl chloride i ka ʻoihana. Hoʻohana nui ʻia ia ma nā kahua o nā 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 ka benzaldehyde, butyl benzyl phthalate, aniline, phoxim, a me benzyl chloride. Penicillin, benzyl alcohol, phenylacetonitrile, phenylacetic acid a me nā huahana ʻē aʻe.

No ka papa benzyl halide o nā hui hoʻonāukiuki ʻo Benzyl chloride. Ma ke ʻano o nā pesticides, ʻaʻole hiki iā ia ke synthesize pololei i ka organophosphorus fungicides rice blast net a me ka iso rice blast net, akā hiki ke hoʻohana ʻia ma ke ʻano he mea maka koʻikoʻi no nā mea waena ʻē aʻe he nui, e like me ka synthesis o phenylacetonitrile a me benzene. Formyl chloride, m-phenoxybenzaldehyde, a pēlā aku. Eia kekahi, hoʻohana nui ʻia ka benzyl chloride i ka lāʻau lapaʻau, nā mea ʻala, nā mea kōkua dye, nā resins synthetic, a pēlā aku. He mea nui ia no ka hana kemika a me nā lāʻau lapaʻau. A laila, ʻo ka wai ʻōpala a i ʻole ka ʻōpala i hana ʻia e nā ʻoihana i ka wā o ke kaʻina hana e loaʻa mau ana ka nui o nā mea waena benzyl chloride.

He mea hoʻoulu waimaka ka Benzyl chloride ponoʻī, he mea ʻawahia loa, he mea hoʻopuka i nā maʻi kanesa, a he mea paʻa i ke kaiapuni. ʻOiai ua hoʻohana nui ʻia ka benzyl chloride ponoʻī a hoʻohana nui ʻia, kahe ka benzyl chloride i ka wā o ka lawe ʻana a i ʻole ua hana ʻia e nā mea hana like ʻole. ʻO ka wai ʻōpala i loaʻa ka benzyl chloride i lawe ʻia e ka ʻoihana i ka wā o ke kaʻina hana a i ʻole e hoʻolei pololei ʻia ka ʻōpala, a i ʻole e kahe ana ka wai i ka wā o ke kaʻina hana, kahi e hoʻokomo pololei ai i ka benzyl chloride i ka lepo a hoʻohaumia i ka lepo.
