Habka 2,4-Dichlorotoluene iyo isticmaalka
Sifooyinka kiimikada: dareere aan midab lahayn oo hufan.
Isticmaal:
1) Waxaa loo isticmaalaa sidii dhexdhexaadin sunta cayayaanka, midabaynta iyo daawooyinka, oo loo isticmaalo soo saarista 2,4-dichlorobenzaldehyde, daawooyinka sida adipine, buprofen, iwm.
2) 2,4-Dichlorotoluene waa mid ka mid ah bakteeriyada diniconazole iyo benzylchlorotriazole, Chemicalbook sidoo kale waa walaxda cayriin ee loogu talagalay diyaarinta 2,4-dichlorobenzaldehyde.
3) Alaab ceeriin ah oo dabiici ah oo loo isticmaalo warshadaha dawooyinka si loo soo saaro daawooyinka ka hortagga duumada, Adepine, iyo isku-darka aashitada ventral. Waxaa loo isticmaalaa daawada cayayaanka disha si loo soo saaro 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, iyo 2,4-dichlorobenzoic acid.

Waxaa jira laba hab oo macmal ah oo loogu talagalay hababka wax soo saarka.
1. Habka 1.2,4-dichlorotoluene wuxuu adeegsadaa 2,4-diaminotoluene oo ah walxo ceeriin ah, waxaana lagu helaa diazotization iyo koloriin. Ku rid aashitada hydrochloric iyo biyaha dheriga falgalka, ku kululee ilaa 50℃, ku milmi 2,4-diaminotoluene adigoo walaaqaya, ka dibna ku rid aashitada hydrochloric iyo cuprous chloride dheriga, ku dar 1% xalka sodium nitrite si siman ugu dar Chemicalbook. Heerkulka waxaa lagu hayaa qiyaastii 60 ℃, istaag si aad u dahaadho, badeecada cayriin ee hoose waxaa lagu dhaqaa biyo ilaa ay dhexdhexaad noqoto, alkali waxaa lagu daraa alkali, ka dibna waxaa lagu dhaqaa biyo si looga saaro alkali, 2,4-dichlorotoluene cayriin ah waa la kala saaraa, badeecada la dhammeeyayna waa la uumi saaraa. . Habka 2.3-chloro-4-toluidine waxaa lagu helaa falgalka diazotization oo leh sodium nitrite, iyo falgalka Sandmeyer oo leh copper chloride.

2.Habka wax soo saarka iyo hababka diyaarinta waa sidan soo socota. Habka parachlorotoluene, p-chlorotoluene iyo catalyst ZrCl4 ayaa la geliyaa falgalka, gaaska koloriin-kana waa la neefsadaa si loo fuliyo falgalka koloriin-ka. Xaddiga gaaska koloriin-ka ayaa la xakameeyaa ilaa dhammaadka falgalka oo falgalka waa la joojiyaa. Falgalka la helay wuxuu ka kooban yahay 85.1% 2,4-dichlorotoluene. Haddii FeCl3 loo isticmaalo sidii catalyst si loo fuliyo falgalka koloriin-ka 10~15℃ ilaa cufnaanta qaraabada ah ee xalka uu noqdo 1.025, badeecadu waxay ka kooban tahay 2,4-dichlorotoluene iyo 3,4-dichlorotoluene, saamiga cufka labada qayboodna waa 100:30. Ka dib marka koloriin-ka la dhammeeyo, ku dhaq biyo si dhexdhexaad ah, oo ku dawee 10% xal NaOH ah 100~110℃ si aad uga saarto wasakhda kale. Koloriin-ka la daweeyay waa la saxaa oo lagu kala saaraa munaar sixitaan oo waxtar sare leh (2,4-dichloro Toluene bp200°C, 3,4-dichlorotoluene bp207°C). Wax soo saarka 2,4-dichlorotoluene iyo 3,4-dichlorotoluene waxay ahaayeen 64.4% iyo 19.8%, siday u kala horreeyaan. Habka Ortho-chlorotoluene o-chlorotoluene wuxuu isticmaalaa sulfuryl chloride sida wakiilka koloriinta si uu u sameeyo falgalka koloriinta 142~196℃. Badeecadaha waa 2,4-dichlorotoluene iyo 2,3-dichlorotoluene, oo aan falcelin lahayn. Halabuurka walxaha ceeriinku waa 55%, 6%, iyo 39%, siday u kala horreeyaan. Ka dib markii la sifeeyo (2,4-dichlorotoluene bp 200°C, 2,3-dichlorotoluene bp 207-208°C, o-chlorotoluene bp 157-159°C), 2,4-dichlorotoluene ayaa la kala saaray. Habka Ortho-nitrotoluene Ortho-nitrotoluene waxaa lagu daraa koloriin iyadoo la joogo kataliyaha FeCl3 35～40℃. Marka cufnaanta qaraabada ah ee fal-galiyaha uu gaaro 1.320 (15℃), ku dhaq walxaha si dhexdhexaad ah, fal-galiyahana wuxuu ka kooban yahay 15% walxaha ceeriin ah, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21%, iyo 15% polychloride, ka dib sixitaanka iyo daaweynta crystallization, Buugga Kiimikada ilaa 2-chloro-6-nitrotoluene Wax-soo-saarka 4-chloro-2-nitrotoluene iyo 4-chloro-2-nitrotoluene waa 50% iyo 30% siday u kala horreeyaan. 4-chloro-2-nitrotoluene waxaa lagu helaa falcelinta yaraynta hydrogenation iyo kala-soocidda uumiga si loo helo 4-chloro-2-amino. Toluene, diazotization iyo ku darista CH2Cl2 falcelinta Sandmeyer si loo helo 2,4-dichlorotoluene. Habka waxaa loo isticmaalaa in lagu soo saaro 4-chloro-2-nitrotoluene kaas oo ah wax soo saar ka soo jeeda 2-chloro-6-nitrotoluene (oo loo isticmaalo dhexdhexaad ka mid ah quinclorac-ga geedaha lagu buufiyo). Habka 2,4-Diaminotoluene 2,4-Diaminotoluene wuxuu maraa falgalka diazotization iyadoo ay joogaan NaNO2 iyo hydrochloric acid, ka dibna wuxuu sameeyaa falgalka Sandmeyer isagoo jooga Cu2Cl2 si loo helo 2,4-dichlorotoluene. Habka 3-Chloro-4-methylaniline 3-chloro-4-methylaniline iyo hydrochloric acid ayaa lagu daraa kiltarka falgalka, xalka biyaha NaNO2 waxaa lagu daraa 3~5℃, ka dibna waxaa lagu dhammeeyaa 2~3h gudahood si loo helo diazotization Ka dib falgalka, dareeraha diazotized waxaa lagu daraa dropwise xal hydrochloric acid ah oo ka kooban Cu2Cl2 2-5°C si loo sameeyo falgalka Sandmeyer si loo helo 2,4-dichlorotoluene. Hababka kor ku xusan, koloriin-ka lagu soo saaro iyadoo la adeegsanayo p-chlorotoluene iyo o-chlorotoluene oo ah walxo ceeriin ah waxa ku jira wasakh badan waxayna leeyihiin dhibco karkaraya oo isku mid ah. Waxaa lagama maarmaan ah in la isticmaalo munaaradaha hagaajinta waxtarka sare leh si loo kala qaybiyo si loo helo in ka badan 98% 2,4-dichlorotoluene. Labadan hab way adag tahay in la shaqeeyo, kharashka maalgashiga qalabkuna waa sarreeyaa. Habka 2,4-diaminotoluene kuma habboona warshadaha, habka o-nitrotoluene iyo habka 3-chloro-4-methylaniline si loo diyaariyo 2,4-dichlorotoluene waxay leeyihiin mabaadi'da aasaasiga ah ee isku midka ah, labaduba waxay u baahan yihiin diazotization iyo Sandmeyer Jawaab ahaan, waxaa jira yaraanta biyaha qashinka badan. Habka o-nitrotoluene waxaa loo isticmaalaa in lagu wada soo saaro 2-chloro-6-nitrotoluene, kaas oo si dheeraad ah loo dhimay si loo helo 2-chloro-6-aminotoluene, kaas oo ah dhexdhexaad muhiim u ah soo saarista quinclorac-ka geedaha lagu buufiyo.
