Ma muli o ka ulu wikiwiki ʻana o nā ʻoihana i lalo, ua lilo koʻu ʻāina i mea hana nui loa o ka honua i ka p-chlorotoluene.Ma waho aʻe o ka hoʻokō ʻana i nā pono o ka mākeke kūloko, lawe ʻia nā huahana i nā mākeke o waho.
ʻO ka p-Chlorotoluene, ka mea i ʻike ʻia ʻo 4-chlorotoluene, aia ke ʻano molekala C7H7Cl.ʻO ka hiʻohiʻona o ka p-chlorotoluene he wai kala ʻole a maopopo, me ka ʻala kūikawā, ka ʻawaʻawa a me ka huhū.ʻAʻole hiki ke hoʻoheheʻe ʻia ka p-Chlorotoluene i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka waiʻona, etera, benzene, acetone, chloroform, etc. nā ipu.ʻO Para-chlorotoluene ka ʻano huahana koʻikoʻi ma waena o nā isomer ʻekolu o ka chlorotoluene.
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka p-chlorotoluene ka nui o ka toluene aromatic ring chlorination method, p-toluidine diazotization method a pēlā aku.I waena o lākou, ʻo ka toluene aromatic ring chlorination method ka hana hoʻomākaukau nui.Hoʻohana ʻo ia i ka toluene maloʻo ma ke ʻano he mea maka, hoʻohui i kahi catalyst, hoʻokomo i ke kinoea chlorine, hana i ka hopena chlorination ma lalo o kahi kūlana wela e loaʻa ai kahi huahana, a laila e hana i kahi kaʻina kaʻawale e loaʻa ai ka p-chlorotoluene.ʻO ka huahana o kēia ʻano ka hui ʻana o ka p-chlorotoluene a me ka o-chlorotoluene.Ma ke kaʻina hana, aia nā ʻokoʻa i ka ratio puka o nā mea ʻelua e hoʻohana ana i nā catalysts ʻokoʻa.ʻO ke ala kaʻawale hiki ke hoʻoponopono i ke ʻano crystallization, molecular sieve adsorption method, etc.
Hoʻohana nui ʻia ka p-Chlorotoluene i ka lāʻau lapaʻau, pesticides, dyes, solvents, organic synthesis a me nā māla ʻē aʻe.Ma ke kahua o ka lāʻau lapaʻau, hiki ke hoʻohana ʻia ka p-chlorotoluene e hana i nā papa clomezadone, pyrimethamine, clotrimide, etc.;ma ke kahua o ka pesticides, hiki ke hoohana ia e hana i na insecticides, herbicides, fungicides, etc.ma ke kahua o ka organik synthesis, hiki ke hoʻohana ʻia e hoʻomākaukau i ka p-chlorobenzaldehyde, p-chlorobenzoic acid, p-chlorobenzonitrile, p-chlorobenzoyl chloride etc.;hiki ke hoʻohana ʻia e like me ka lāʻau, resin solvent.
Wahi a ka "2021-2025 China's p-chlorotoluene market development status and production and sales data analysis report" i hoʻokuʻu ʻia e Xinsijie Industry Research Center, hiki i ka p-chlorotoluene ke hana i nā ʻano like ʻole e hoʻomākaukau ai i nā ʻano huahana kemika maikaʻi, a me kāna mau derivatives. ʻO ia ka mea i koi nui ʻia a hoʻohana nui ʻia ma waena o nā isomers chlorotoluene.Ma muli o ka ulu wikiwiki ʻana o nā ʻoihana i lalo, ua lilo koʻu ʻāina i mea hana nui loa o ka honua i ka p-chlorotoluene.Ma waho aʻe o ka hoʻokō ʻana i nā pono o ka mākeke kūloko, lawe ʻia nā huahana i nā mākeke o waho.Ua manaʻo ʻia mai 2020 a 2025, e ulu ka mākeke p-chlorotoluene honua ma kahi o ka ulu ʻana ma kahi o 4.0%, a ʻo ka ʻoihana p-chlorotoluene o koʻu ʻāina he kūlana hoʻomohala maikaʻi.
ʻO ka hapa nui o nā ʻoihana p-chlorotoluene o koʻu ʻāina e hana i nā huahana o lalo.No laila, i ka hana p-chlorotoluene o koʻu ʻāina, ʻoi aku ka nui o ka hoʻohana ponoʻī ʻana e nā ʻoihana, a he liʻiliʻi ka hapa o ke kūʻai aku.
Wahi a nā mea noiʻi ʻoihana mai Xinsijie, ʻo ka p-chlorotoluene he mea koʻikoʻi kemika maikaʻi a me ka waena kemika maikaʻi.Hoʻohana nui ʻia ia i ka lāʻau lapaʻau, pesticides, dyes a me nā māla ʻē aʻe, a ke hoʻomau nei ka ulu ʻana o ka mākeke.
