Te tikanga whakamahi me te hanga 2,4-Dichlorotoluene
Ngā āhuatanga matū: wai kore tae, mārama hoki.
Whakamahia:
1) Whakamahia hei takawaenga o ngā patupatu, ngā tae me ngā rongoā, e whakamahia ana i roto i te hanga o te 2,4-dichlorobenzaldehyde, ngā rongoā pēnei i te adipine, te buprofen, me ētahi atu.
2) Ko te 2,4-Dichlorotoluene he takawaenga o ngā patu huakita diniconazole me benzylchlorotriazole, ā, ko Chemicalbook anō hoki te rauemi mata mō te hanga i te 2,4-dichlorobenzaldehyde.
3) Ngā rauemi mata hangai waro, e whakamahia ana i roto i te umanga rongoā mō te hanga rongoā ārai mate pāwera, Adepine, me te hanga waikawa ventral. E whakamahia ana i roto i ngā takawaenga patu pepeke hei hanga 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, me te waikawa 2,4-dichlorobenzoic.

E rua ngā tikanga hangahanga mō ngā tikanga whakaputa.
1. Ko te tikanga 1.2,4-dichlorotoluene e whakamahi ana i te 2,4-diaminotoluene hei rauemi mata, ā, ka whiwhi mā te diazotization me te chlorination. Tāpirihia te waikawa hauwaiora me te wai ki roto i te kohua tauhohenga, whakamahanahia ki te 50℃, whakarewahia te 2,4-diaminotoluene me te whakaoho, kātahi ka tāpirihia te waikawa hauwaiora me te pūhaumāota kapuro ki roto i te kohua, tāpirihia te 1% otinga konutai nitrite kia ōrite ki roto i te Chemicalbook. Ka mau tonu te pāmahana ki te 60℃, tū tonu mō te paparanga, ka horoia te hua mata o raro ki te wai kia noho kūpapa, ka tāpirihia te kawakore ki te kawakore, kātahi ka horoia ki te wai hei tango i te kawakore, ka wehea te 2,4-dichlorotoluene mata, ā, ka whakamaroketia te hua kua oti ki te mamaoa. Ka whiwhi te tikanga 2.3-chloro-4-toluidine mā te tauhohenga diazotization me te konutai nitrite, me te tauhohenga Sandmeyer me te konupūmā konupūmā.

2.Ko te tikanga whakaputa me ōna tikanga whakarite koia ēnei. I roto i te tikanga parachlorotoluene, ka tukuna te p-chlorotoluene me te whakakorikori ZrCl4 ki roto i te tauhohenga, ā, ka tukuna te hau chlorine ki waho hei whakahaere i te tauhohenga chlorine. Ka whakahaeretia te nui o te hau chlorine tae noa ki te mutunga o te tauhohenga, ā, ka mutu te tauhohenga. Kei roto i te matū tauhohenga i whiwhihia he 85.1% o te 2,4-dichlorotoluene. Mena ka whakamahia te FeCl3 hei whakakorikori hei whakahaere i te tauhohenga chlorine i te 10～15℃ tae noa ki te 1.025 te mātotoru whanaunga o te otinga, kei roto i te hua te 2,4-dichlorotoluene me te 3,4-dichlorotoluene, ā, ko te ōwehenga papatipu o ngā wāhanga e rua he 100:30. Kia oti te whakakorikori, horoia ki te wai kia kore e pāngia, ka rongoatia ki te 10% NaOH otinga i te 100～110℃ hei tango i ētahi atu poke. Ka whakatikatikahia te pūhaumāota kua rongoatia, ā, ka wehea i roto i tētahi pourewa whakatikatika tino whai hua (2,4-dichloro Toluene bp200°C, 3,4-dichlorotoluene bp207°C). Ko ngā hua o te 2,4-dichlorotoluene me te 3,4-dichlorotoluene he 64.4% me te 19.8%, ia. Ko te tikanga Ortho-chlorotoluene Ko te o-chlorotoluene e whakamahi ana i te sulfuryl chloride hei kaihoko whakapūhaumāota hei whakahaere i te tauhohenga whakapūhaumāota i te 142～196℃. Ko ngā hua ko te 2,4-dichlorotoluene me te 2,3-dichlorotoluene, ā, kāore i tauhohe. Ko te hanganga o ngā rauemi mata he 55%, 6%, me te 39%, ia. I muri i te whakatōtō (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 Ka whakamāotaotia te Ortho-nitrotoluene i te aroaro o te whakakorikori FeCl3 i te 35～40℃. Ina tae te mātotoru whanaunga o te matū tauhohe ki te 1.320 (15℃), horoia te rauemi kia kore e pirau, ā, kei roto i te matū tauhohe te 15% o te rauemi mata, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21%, me te 15% polychloride, i muri i te whakatikatika me te maimoatanga tioata, ka whiwhi te pukapuka matū ki te 2-chloro-6-nitrotoluene. Ko ngā hua o te 4-chloro-2-nitrotoluene me te 4-chloro-2-nitrotoluene he 50% me te 30% ia. Ka whiwhihia te 4-chloro-2-nitrotoluene mā te tauhohenga whakaiti hauwai me te whakamaroke mamaoa hei whiwhi i te 4-chloro-2-amino. Toluene, te diazotization me te tāpiri CH2Cl2 mō te tauhohenga Sandmeyer hei whiwhi i te 2,4-dichlorotoluene. Ka whakamahia te tikanga hei whakaputa i te 4-chloro-2-nitrotoluene, he hua taha tēnei o te 2-chloro-6-nitrotoluene (e whakamahia ana hei takawaenga o te patu taru quinclorac). Tikanga 2,4-Diaminotoluene Ka pāngia te 2,4-Diaminotoluene e te tauhohenga diazotization i te aroaro o te NaNO2 me te waikawa hauwaiora, kātahi ka mahi i te tauhohenga Sandmeyer i te aroaro o te Cu2Cl2 hei whiwhi i te 2,4-dichlorotoluene. Tikanga 3-Chloro-4-methylaniline Ka tāpirihia te 3-chloro-4-methylaniline me te waikawa hauwaiora ki te ipu tauhohenga, ka tāpirihia te otinga wai NaNO2 mā te maturuturu i te 3～5℃, ā, ka oti te tāpiri i roto i te 2～3h mō te diazotization. I muri i te tauhohenga, ka tāpirihia te wai diazotized mā te maturuturu ki te otinga waikawa hauwaiora kei roto ko te Cu2Cl2 i te 2-5°C hei mahi i te tauhohenga Sandmeyer hei whiwhi i te 2,4-dichlorotoluene. I roto i ngā tikanga o runga ake nei, he maha ngā poke o te pūhaumāota i hangaia mā te whakamahi i te p-chlorotoluene me te o-chlorotoluene hei rauemi mata, ā, he rite tonu ngā pūmahana kohua. Me whakamahi i ngā pourewa whakatikatika tino whai hua hei wehewehe kia whiwhi ai i te neke atu i te 98% o te 2,4-dichlorotoluene. He uaua te whakahaere i ēnei tikanga e rua, ā, he nui te utu haumi taputapu. Kāore te tikanga 2,4-diaminotoluene i te pai mō te ahumahi, ā, he rite tonu ngā mātāpono taketake o te tikanga o-nitrotoluene me te tikanga 3-chloro-4-methylaniline hei whakarite i te 2,4-dichlorotoluene, ā, me hiahia te diazotization me te Sandmeyer. Hei whakautu, he ngoikoretanga o te nui ake o te wai para. Ka whakamahia te tikanga o-nitrotoluene hei hanga tahi i te 2-chloro-6-nitrotoluene, ka whakaitihia anō kia whiwhi ai i te 2-chloro-6-aminotoluene, he takawaenga nui mō te hanga o te patu taru quinclorac.
