ʻO ke ʻano hana a me ka hoʻohana ʻana o 2,4-Dichlorotoluene
Nā waiwai kemika: wai ʻole kala a moakaka.
Hoʻohana:
1) Hoʻohana ʻia ma ke ʻano he mau waena o nā pesticides, dyes a me nā lāʻau lapaʻau, i hoʻohana ʻia i ka hana ʻana o 2,4-dichlorobenzaldehyde, nā lāʻau lapaʻau e like me adipine, buprofen, a pēlā aku.
2) ʻO 2,4-Dichlorotoluene kahi waena o nā bactericides diniconazole a me benzylchlorotriazole, a ʻo Chemicalbook nō hoʻi ka mea maka no ka hoʻomākaukau ʻana o 2,4-dichlorobenzaldehyde.
3) Nā mea maka synthetic organik, i hoʻohana ʻia i ka ʻoihana lāʻau lapaʻau no ka hana ʻana i nā lāʻau antimalarial, Adepine, a me ka synthesis o ka waikawa ventral. Hoʻohana ʻia i nā mea waena pesticide e hana i ka 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, a me 2,4-dichlorobenzoic acid.

Aia ʻelua mau ʻano hana synthetic no nā ʻano hana.
1. Hoʻohana ke ʻano hana 1.2,4-dichlorotoluene i ka 2,4-diaminotoluene ma ke ʻano he mea maka, a loaʻa ia ma o ka diazotization a me ka chlorination. E kau i ka waikawa hydrochloric a me ka wai i loko o ka ipu hana, e hoʻomehana i 50 ℃, e hoʻoheheʻe i ka 2,4-diaminotoluene ma lalo o ka hoʻoulu ʻana, a laila e kau i ka waikawa hydrochloric a me ka cuprous chloride i loko o ka ipu, e hoʻohui like i ka 1% sodium nitrite solution i loko o Chemicalbook, Mālama ʻia ka mahana ma kahi o 60 ℃, e kū mālie no ka layering, holoi ʻia ka huahana maka haʻahaʻa me ka wai a hiki i ka neutral, hoʻohui ʻia ka alkali i ka alkali, a laila holoi ʻia me ka wai e wehe i ka alkali, hoʻokaʻawale ʻia ka 2,4-dichlorotoluene maka, a hoʻoheheʻe ʻia ka huahana i hoʻopau ʻia i ka mahu. . Loaʻa ke ʻano hana 2.3-chloro-4-toluidine ma o ka hana diazotization me ka sodium nitrite, a me ka hana Sandmeyer me ke keleawe chloride.

2.ʻO ke ʻano hana a me kāna mau ʻano hoʻomākaukau penei. Ma ke ʻano parachlorotoluene, hoʻokomo ʻia ka p-chlorotoluene a me ka mea hoʻouluulu ZrCl4 i loko o ka reactor, a hoʻokuʻu ʻia ke kinoea chlorine e hoʻokō i ka hopena chlorination. Hoʻomalu ʻia ka nui o ke kinoea chlorine a hiki i ka hopena o ka hopena a ua hoʻōki ʻia ka hopena. Loaʻa i ka mea hoʻouluulu i loaʻa he 85.1% o 2,4-dichlorotoluene. Inā hoʻohana ʻia ʻo FeCl3 ma ke ʻano he mea hoʻouluulu e hoʻokō i ka hopena chlorination ma 10～15℃ a hiki i ka nui o ka hopena he 1.025, aia ka huahana i ka 2,4-dichlorotoluene a me 3,4-dichlorotoluene, a ʻo ka lakio nui o nā ʻāpana ʻelua he 100:30. Ma hope o ka pau ʻana o ka chlorination, holoi me ka wai i ka neutrality, a mālama me ka 10% NaOH solution ma 100～110℃ e wehe i nā haumia ʻē aʻe. Hoʻoponopono ʻia ka chloride i mālama ʻia a hoʻokaʻawale ʻia i loko o kahi hale kiaʻi hoʻoponopono kiʻekiʻe (2,4-dichloro Toluene bp200°C, 3,4-dichlorotoluene bp207°C). ʻO nā hua o 2,4-dichlorotoluene a me 3,4-dichlorotoluene he 64.4% a me 19.8%, kēlā me kēia. Hoʻohana ke ʻano Ortho-chlorotoluene o-chlorotoluene i ka sulfuryl chloride ma ke ʻano he mea chlorinating e hoʻokō i ka hopena chlorination ma 142～196℃. ʻO nā huahana he 2,4-dichlorotoluene a me 2,3-dichlorotoluene, a ʻaʻole i hana hou ʻia. ʻO ka haku mele ʻana o nā mea maka he 55%, 6%, a me 39%, kēlā me kēia. Ma hope o ka hoʻoheheʻe ʻana (2,4-dichlorotoluene bp 200°C, 2,3-dichlorotoluene bp 207-208°C, o-chlorotoluene bp 157-159°C), ua hoʻokaʻawale ʻia ʻo 2,4-dichlorotoluene. Ke ʻano hana Ortho-nitrotoluene Hoʻohuihui ʻia ʻo Ortho-nitrotoluene i ke chlorine i ke alo o ka mea hoʻoulu FeCl3 ma 35～40℃. Ke hiki ka nui o ka reactant i 1.320 (15 ℃), e holoi i ka mea i ke kūlike ʻole, a loaʻa i ka reactant he 15% o ka mea maka, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21%, a me 15% polychloride, ma hope o ka hoʻoponopono ʻana a me ka mālama ʻana i ka crystallization, ʻo ka Chemicalbook i 2-chloro-6-nitrotoluene ʻO nā hua o 4-chloro-2-nitrotoluene a me 4-chloro-2-nitrotoluene he 50% a me 30% pakahi. Loaʻa ka 4-chloro-2-nitrotoluene ma o ka hana hoʻemi hydrogenation a me ka distillation mahu e loaʻa ai ka 4-chloro-2-amino. Toluene, diazotization a me ka hoʻohui ʻana iā CH2Cl2 no ka hana Sandmeyer e loaʻa ai ka 2,4-dichlorotoluene. Hoʻohana ʻia ke ʻano hana e hana i ka 4-chloro-2-nitrotoluene ʻo ia ka huahana ʻaoʻao o 2-chloro-6-nitrotoluene (hoʻohana ʻia ma ke ʻano he waena o ka herbicide quinclorac). 2,4-Diaminotoluene Hana 2,4-Diaminotoluene Hana ʻia ka hopena diazotization i ke alo o NaNO2 a me ka waikawa hydrochloric, a laila hana i ka hopena Sandmeyer i ke alo o Cu2Cl2 e loaʻa ai ka 2,4-dichlorotoluene. 3-Chloro-4-methylaniline Hana 3-chloro-4-methylaniline a me ka waikawa hydrochloric i hoʻohui ʻia i loko o ka ipu hao hana, hoʻohui ʻia ka hopena wai NaNO2 i kulu ma 3～5℃, a hoʻopau ʻia ka hoʻohui ʻana i loko o 2～3h no ka diazotization Ma hope o ka hana ʻana, hoʻohui ʻia ka wai diazotized i kulu i kahi hopena waikawa hydrochloric e loaʻa ana iā Cu2Cl2 ma 2-5°C e hana i ka hopena Sandmeyer e loaʻa ai ka 2,4-dichlorotoluene. Ma waena o nā ʻano hana i luna, ʻo ka chloride i hana ʻia ma ka hoʻohana ʻana i ka p-chlorotoluene a me ka o-chlorotoluene ma ke ʻano he mau mea maka he nui nā haumia a he like nā kiko paila. Pono e hoʻohana i nā hale kiaʻi hoʻoponopono kiʻekiʻe e hoʻokaʻawale e loaʻa ma mua o 98% o 2,4-dichlorotoluene. He paʻakikī ke hana i kēia mau ʻano hana ʻelua, a he kiʻekiʻe ke kumukūʻai hoʻopukapuka lako. ʻAʻole kūpono ke ʻano hana 2,4-diaminotoluene no ka ʻoihana, a ʻo ke ʻano hana o-nitrotoluene a me ke ʻano hana 3-chloro-4-methylaniline e hoʻomākaukau i ka 2,4-dichlorotoluene he mau loina kumu like, a pono nā mea ʻelua i ka diazotization a me Sandmeyer. I ka pane ʻana, aia kahi hemahema o ka wai ʻōpala hou aku. Hoʻohana ʻia ke ʻano hana o-nitrotoluene e hana pū i ka 2-chloro-6-nitrotoluene, kahi i hoʻemi hou ʻia e loaʻa ai ka 2-chloro-6-aminotoluene, he mea koʻikoʻi ia no ka hana ʻana o ka herbicide quinclorac.
