2,4-Dichlorotoluene te whakamahi me te tikanga whakahiato
Ngā āhuatanga matū: te wai kore tae me te wai mārama.
Whakamahia:
1) Ka whakamahia hei takawaenga o te pesticides, te waikano me te rongoa, whakamahia i roto i te hanga 2,4-dichlorobenzaldehyde, raau taero penei i te adipine, buprofen, etc.
2) Ko te 2,4-Dichlorotoluene he takawaenga o te bactericides diniconazole me te benzylchlorotriazole, a ko Chemicalbook hoki te rauemi mata mo te whakarite i te 2,4-dichlorobenzaldehyde.
3) Ko nga rauemi mata waihanga, whakamahia i roto i te umanga rongoa mo te hanga o nga raau taero antimalarial, Adepine, me te whakahiato o te waikawa ventral.Ka whakamahia i roto i nga takawaenga pesticide ki te hanga 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, me te 2,4-dichlorobenzoic acid.

E rua nga tikanga waihanga mo nga tikanga whakaputa.
1. Ko te tikanga 1.2,4-dichlorotoluene e whakamahi ana i te 2,4-diaminotoluene hei rauemi mata, ka whiwhihia e te diazotization me te chlorination.Hoatuhia te waikawa pūhaumāota me te wai ki roto i te kohua tauhohenga, whakamahana ki te 50 ℃, memeha 2,4-diaminotoluene i raro i te whakaoho, katahi ka maka te waikawa pūhaumāota me te kapu pūhaumāota ki roto i te kohua, tāpirihia te 1% konutai nitrite otinga ki roto i te Chemicalbook, Ka mau tonu te pāmahana ki te tata ki te 60 ℃, tu tonu mo te paparanga, ka horoia te hua masivesivá raro ki te wai tae noa ki te noho kore, ka tapirihia te alkali ki te kawakawa, katahi ka horoia ki te wai hei tango i te kawakore, ka wehea te 2,4-dichlorotoluene masivesivá, me te Ko te hua kua oti te whakamakuku mamaoa..Ko te tikanga 2.3-chloro-4-toluidine ka whiwhi ma te tauhohenga diazotization me te konutai nitrite, me te tauhohenga Sandmeyer me te konupora chloride.

2.Ko te tikanga whakaputa me ona tikanga whakarite e whai ake nei.I roto i te tikanga parachlorotoluene, ka makahia te p-chlorotoluene me te whakakorikori ZrCl4 ki roto i te reactor, ka tukuna te hau maota ki te kawe i te tauhohenga maaota.Ka whakahaeretia te nui o te hau maota ki te mutunga o te tauhohenga ka mutu te tauhohenga.Kei roto i te reactant te 85.1% o te 2,4-dichlorotoluene.Mēnā ka whakamahia te FeCl3 hei whakakōkī ki te kawe i te tauhohenga māota i te 10～15 ℃ tae noa ki te 1.025 te kiato whanaunga o te otinga, kei roto i te hua te 2,4-dichlorotoluene me te 3,4-dichlorotoluene, me te ōwehenga papatipu o te rua. Ko nga waahanga he 100:30.I muri i te otinga o te whakamaarama, horoia ki te wai kia kore noa, ka rongoa ki te otinga NaOH 10% i te 100～110℃ hei tango i etahi atu poke.Ko te chloride kua tukinotia ka whakatikahia, ka wehea i roto i te pourewa whakatikatika tino pai (2,4-dichloro Toluene bp200°C, 3,4-dichlorotoluene bp207°C).Ko nga hua o te 2,4-dichlorotoluene me te 3,4-dichlorotoluene he 64.4% me te 19.8%.Ko te tikanga Ortho-chlorotoluene o-chlorotoluene e whakamahi ana i te sulfuryl chloride hei kaihoko maaota hei kawe i te tauhohenga maaota i te 142～196℃.Ko nga hua ko te 2,4-dichlorotoluene me te 2,3-dichlorotoluene, me te kore urupare Ko te hanganga o nga rauemi mata he 55%, 6%, me te 39%.I muri i te whakakorenga (2,4-dichlorotoluene bp 200°C, 2,3-dichlorotoluene bp 207-208°C, o-chlorotoluene bp 157-159°C), ka wehea te 2,4-dichlorotoluene.Tikanga Ortho-nitrotoluene Ko te Ortho-nitrotoluene ka maota i te aroaro o te FeCl3 catalyst i te 35～40 ℃.Ina tae te kiato whanaunga o te tauhohenga ki te 1.320 (15 ℃), horoia te rauemi ki te kupapa, ka 15% o te reactant kei roto , 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21% , me te 15% polychloride, i muri i te whakatikatika me te maimoatanga tioata, te Puka Maama ki te 2-chloro-6-nitrotoluene Ko nga hua o te 4-chloro-2-nitrotoluene me te 4-chloro-2-nitrotoluene he 50% me te 30%.Ka whiwhihia te 4-chloro-2-nitrotoluene na roto i te tauhohenga whakaheke hauwai me te whakamaarama mamaoa kia whiwhi 4-chloro-2-amino.Toluene, diazotization me te tāpiri CH2Cl2 mo Sandmeyer tauhohenga ki te whiwhi 2,4-dichlorotoluene.Ka whakamahia te tikanga ki te whakaputa i te 4-chloro-2-nitrotoluene he hua na te 2-chloro-6-nitrotoluene (i whakamahia hei takawaenga o te quinclorac herbicide).2,4-Diaminotoluene Tikanga 2,4-Diaminotoluene ka tukuna te tauhohenga diazotization i te aroaro o te NaNO2 me te waikawa pūhaumāota, a ka mahi Sandmeyer tauhohenga i te aroaro o Cu2Cl2 ki te whiwhi 2,4-dichlorotoluene.Tikanga 3-Chloro-4-methylaniline Ko te 3-chloro-4-methylaniline me te waikawa pūhaumāota ka tāpirihia ki te ketere tauhohenga, ka tāpirihia te wairewa wai NaNO2 ki te maturuturunga iho i te 3～5℃, ka oti te taapiri i roto i te 2～3h mo te whakamaaramatanga I muri i te Ko te tauhohenga, ka tapirihia te wai diazotized ki te wairewa waikawa hauwai kei roto Cu2Cl2 i te 2-5°C hei mahi i te tauhohenga Sandmeyer kia whiwhi 2,4-dichlorotoluene.I roto i nga tikanga o runga ake nei, he maha nga poke o te chloride i hangaia ma te whakamahi i te p-chlorotoluene me te o-chlorotoluene hei rauemi mata, he maha nga poke, he rite ano nga tohu koropupuu.He mea tika ki te whakamahi i nga pourewa whakatikatika kaha ki te hautau kia nui ake i te 98% o te 2,4-dichlorotoluene.Ko enei tikanga e rua he uaua ki te whakahaere, he nui te utu mo te haumi taputapu.Ko te tikanga 2,4-diaminotoluene e kore e pai mo te ahumahi, me te tikanga o-nitrotoluene me te tikanga 3-chloro-4-methylaniline ki te whakarite i te 2,4-dichlorotoluene he rite tonu nga kaupapa matua, me te hiahia e rua te diazotization me Sandmeyer Hei whakautu. , he hapa te nui ake o te wai para.Ka whakamahia te tikanga o-nitrotoluene ki te hanga tahi i te 2-chloro-6-nitrotoluene, ka whakahekehia ano kia whiwhi 2-chloro-6-aminotoluene, he takawaenga nui mo te hanga o te quinclorac herbicide.
