2,4-Dichlorotoluene isticmaalka iyo habka synthesis
Waxyaabaha kiimikada: dareere aan midab lahayn oo hufan.
Isticmaal:
1) Waxaa loo istcimaalay dhexdhexaadinta sunta cayayaanka, dheeha iyo dawooyinka, loo isticmaalo soo saarista 2,4-dichlorobenzaldehyde, dawooyinka sida adipine, buprofen, iwm.
2) 2,4-Dichlorotoluene waa dhex-dhexaadka bakteeriyada diniconazole iyo benzylchlorotriazole, iyo Kiimikada sidoo kale waa alaabta ceeriin ee diyaarinta 2,4-dichlorobenzaldehyde.
3) Qalabka ceyriinka ah ee dabiiciga ah, oo loo isticmaalo warshadaha dawooyinka si loogu soo saaro dawooyinka ka hortagga duumada, Adepine, iyo isku dhafka ventral acid. Loo isticmaalo dhex-dhexaadinta sunta cayayaanka si loo soo saaro 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, iyo 2,4-dichlorobenzoic acid.

Waxaa jira laba hab oo synthetic hababka wax soo saarka.
1. Habka 1.2,4-dichlorotoluene wuxuu isticmaalaa 2,4-diaminotoluene sida walxo ceeriin ah, waxaana lagu helaa diazotization iyo koloriin. Ku rid hydrochloric acid iyo biyaha dheriga falcelinta, kulaylka 50 ℃, milaan 2,4-diaminotoluene hoos walaaqda, ka dibna ku rid hydrochloric acid iyo koobabka chloride dheriga, ku dar 1% sodium nitrite si siman kitaabka Kiimikada, Heerkulka waxaa lagu hayaa at Qiyaastii 60 ℃, u istaag inaad isku dhejiso, alaabta ceeriin ee hoose waxaa lagu dhaqaa biyo ilaa ay dhexdhexaad tahay, alkali waxaa lagu daraa alkali, ka dibna lagu dhaqo biyo si looga saaro alkali, 2,4-dichlorotoluene cayriin waa la kala saaraa, iyo Alaabta dhammaatay waa uumi diiray. . Habka 2.3-chloro-4-toluidine waxaa lagu helaa falcelinta diazotization ee sodium nitrite, iyo falcelinta Sandmeyer oo leh koloriin naxaas ah.

2.Habka wax soo saarka iyo hababka diyaarintiisa waa sida soo socota. Habka parachlorotoluene, p-chlorotoluene iyo kicinta ZrCl4 ayaa la gelinayaa reactor-ka, gaaska chlorine-ka ayaa la soo shiday si loo fuliyo falcelinta koloriinta. Qadarka gaasta chlorine waa la xakameynayaa ilaa dhamaadka falcelinta oo falcelinta waa la joojiyaa. Dareen-celinta la helay ayaa ka kooban 85.1% 2,4-dichlorotoluene. Haddii FeCl3 loo isticmaalo kicinta si loo fuliyo fal-celinta koloriinta 10 ~ 15 ℃ ilaa cufnaanta qaraabada ee xalku ka yahay 1.025, badeecaddu waxay ka kooban tahay 2,4-dichlorotoluene iyo 3,4-dichlorotoluene, iyo saamiga tirada labada qaybaha waa 100:30. Ka dib marka koloriinta la dhammeeyo, ku maydh biyo si aad dhexdhexaad u noqoto, oo ku daaweyso 10% NaOH 100～110℃ si aad uga saarto wasakhyada kale. Koloridhida la daweeyay waa la saxay oo lagu kala soocay munaarad sixitaan oo tayo 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 waxay isticmaashaa sulfuryl chloride sida wakiilka koloriinta si ay u sameyso falcelinta koloriinta at 142～196℃. Alaabooyinku waa 2,4-dichlorotoluene iyo 2,3-dichlorotoluene, oo aan la falgelin Halabuurka alaabta ceeriin waa 55%, 6%, iyo 39%, siday u kala horreeyaan. Distillation ka dib (2,4-dichlorotoluene bp 200°C, 2,3-dichlorotoluene bp 207-208°C, o-chlorotoluene bp 157-159°C), 2,4-dichlorotoluene waa la kala saaray. Habka Ortho-nitrotoluene Ortho-nitrotoluene waa koloriin iyadoo ay jirto joogitaanka FeCl3 ee 35-40 ℃. Marka cufnaanta qaraabada ah ee falcelinta gaadho 1.320 (15 ℃), ku maydh walxaha si dhexdhexaad ah, fal celisiyuhuna waxa uu ka kooban yahay 15% walxaha ceeriin, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21% , iyo 15% polychloride, ka dib hagaajinta iyo daaweynta crystallization, Kiimikada 2-chloro-6-nitrotoluene Wax-soosaarka 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 dhimista hydrogenation-ka iyo kala-goynta 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 ka soo baxa 2-chloro-6-nitrotoluene (oo loo isticmaalo dhexdhexaadinta quinclorac herbicide). 2,4-Diaminotoluene Habka 2,4-Diaminotoluene wuxuu maraa falcelinta diazotization ee joogitaanka NaNO2 iyo hydrochloric acid, ka dibna wuxuu sameeyaa falcelinta Sandmeyer ee joogitaanka Cu2Cl2 si loo helo 2,4-dichlorotoluene. Habka 3-Chloro-4-methylaniline 3-chloro-4-methylaniline iyo hydrochloric acid ayaa lagu daraa kiliga falcelinta, NaNO2 xal aqueous ah ayaa lagu daraa hoos u dhig 3～5℃ Dareen-celinta, dareeraha diazotized ayaa lagu daraa si tartiib tartiib ah xal hydrochloric acid oo ka kooban Cu2Cl2 at 2-5 ° C si loo sameeyo falcelinta Sandmeyer si loo helo 2,4-dichlorotoluene. Waxaa ka mid ah hababka kor ku xusan, chloride-ka waxaa lagu soo saaraa p-chlorotoluene iyo o-chlorotoluene sida alaabta ceeriin waxay ka kooban tahay wasakh badan waxayna leedahay dhibco isku mid ah oo karkaraya. Waa lagama maarmaan in la isticmaalo munaaradaha hagaajinta waxtarka sare leh si loo jajabiyo si loo helo in ka badan 98% ee 2,4-dichlorotoluene. Labadan hab waa ay adag tahay in la shaqeeyo, kharashka maalgashiga qalabkuna waa mid sarreeya. Habka 2,4-diaminotoluene kuma habboona warshadaynta, iyo habka o-nitrotoluene iyo habka 3-chloro-4-methylaniline si loogu diyaariyo 2,4-dichlorotoluene waxay leeyihiin mabaadi'da aasaasiga ah ee isku midka ah, labaduba waxay u baahan yihiin diazotization iyo Sandmeyer Jawaabta. , waxaa jira cillado badan oo biyo wasakh ah. Habka o-nitrotoluene waxaa loo isticmaalaa in lagu soo saaro 2-chloro-6-nitrotoluene, taas oo la sii yareeyo si loo helo 2-chloro-6-aminotoluene, taas oo ah dhexdhexaad muhiim u ah soo saarista quinclorac herbicide.
