2,4-Dichlorotoluene kushandiswa uye synthesis nzira
Chemical properties: isina ruvara uye yakajeka mvura.
Shandisa:
1) Inoshandiswa sepakati pemishonga yezvipembenene, dhayi nemishonga, inoshandiswa mukugadzirwa kwe2,4-dichlorobenzaldehyde, mishonga yakadai seadipine, buprofen, nezvimwewo.
2) 2,4-Dichlorotoluene inhengo yepakati ye bactericides diniconazole uye benzylchlorotriazole, uye Chemicalbook ndiyowo yakasvibiswa yekugadzirira kwe2,4-dichlorobenzaldehyde.
3) Organic synthetic raw materials, inoshandiswa muindasitiri yemishonga kugadzirwa kwemishonga inorwisa marariya, Adepine, uye synthesis yeventral acid. Inoshandiswa mumishonga yezvipembenene yepakati kugadzira 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, uye 2,4-dichlorobenzoic acid.

Pane nzira mbiri dzekugadzira dzekugadzira nzira.
1. Iyo 1.2,4-dichloroluene nzira inoshandisa 2,4-diaminotoluene seyakasvibiswa, uye inowanikwa ne diazotization uye chlorination. Isa hydrochloric acid nemvura muhari yekupindura, kupisa kusvika ku50 ℃, nyungudutsa 2,4-diaminotoluene pasi pekukurudzira, wozoisa hydrochloric acid uye cuprous chloride muhari, wedzera 1% sodium nitrite solution zvakaenzana mu Chemicalbook, Tembiricha inochengetwa pa dzinenge 60 ℃, mira mira kuisa layer, iyo yepasi crude product inogezwa nemvura kusvika isina kwayakarerekera, alkali inowedzerwa kune alkali, yozogezwa nemvura kubvisa alkali, iyo isina kuchena 2,4-dichloroluene inoparadzaniswa, uye iyo chigadzirwa chakapedzwa chiri steam distilled. . Iyo 2.3-chloro-4-toluidine nzira inowanikwa ne diazotization reaction ine sodium nitrite, uye Sandmeyer reaction nemhangura chloride.

2.Nzira yekugadzira uye nzira dzekugadzirira kwayo ndezvinotevera. Munzira yeparachlorotoluene, p-chlorotoluene uye catalyst ZrCl4 zvinoiswa mureactor, uye gasi rechlorine rinobudiswa kuti riite chlorination reaction. Huwandu hwe chlorine gasi hunodzorwa kusvika kumagumo ekuita uye mhinduro inomiswa. Iyo yakawanikwa reactant ine 85.1% ye2,4-dichloroluene. Kana FeCl3 ikashandiswa secatalyst kuita chlorination reaction pa10～15℃ kusvika hukama hwemushonga hwasvika 1.025, chigadzirwa chine 2,4-dichloroluene uye 3,4-dichloroluene, uye huwandu hwehuwandu hwezviviri. zvikamu 100:30 . Mushure mekunge chlorination yapera, geza nemvura kusvika kune kwawakarerekera, uye gadzira ne10% NaOH solution pa100～110℃ kubvisa zvimwe tsvina. Iyo chloride inorapwa inogadziriswa uye inoparadzaniswa mune yakakwirira-yepamusoro rectification tower (2,4-dichloro Toluene bp200 ° C, 3,4-dichloroluene bp207 ° C). Zvibereko zve 2,4-dichloroluene uye 3,4-dichloroluene zvaiva 64.4% uye 19.8%, maererano. Ortho-chlorotoluene nzira o-chlorotoluene inoshandisa sulfuryl chloride seyo chlorinating agent kuita chlorination reaction pa142～196℃. Zvigadzirwa ndeye 2,4-dichloroluene uye 2,3-dichloroluene, uye isingasviki Kuumbwa kwezvinhu zvakasvibiswa ndeye 55%, 6%, uye 39%, maererano. Mushure mokunge distillation (2,4-dichloroluene bp 200 ° C, 2,3-dichloroluene bp 207-208 ° C, o-chlorotoluene bp 157-159 ° C), 2,4-dichloroluene yakaparadzaniswa. Ortho-nitrotoluene nzira Ortho-nitrotoluene inonatswa pamberi peFeCl3 catalyst pa35～40℃. Kana huwandu hwehukama hweiyo reactant hwasvika 1.320 (15 ℃), geza zvinhu kuti zvisarerekera, uye reactant ine 15% yezvakagadzirwa, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21% , uye 15% polychloride, mushure mekugadzirisa uye crystallization kurapwa, Chemicalbook kusvika 2-chloro-6-nitrotoluene Zvibereko zve 4-chloro-2-nitrotoluene uye 4-chloro-2-nitrotoluene ndeye 50% uye 30% maererano. 4-chloro-2-nitrotoluene inowanikwa nehydrogenation reduction reaction uye steam distillation kuti iwane 4-chloro-2-amino. Toluene, diazotization uye kuwedzera CH2Cl2 yeSandmeyer kuita kuti uwane 2,4-dichlorrotoluene. Nzira iyi inoshandiswa kugadzira 4-chloro-2-nitrotoluene inova-chigadzirwa che2-chloro-6-nitrotoluene (inoshandiswa sepakati pemushonga wesora quinclorac). 2,4-Diaminotoluene Method 2,4-Diaminotoluene inopinda diazotization reaction pamberi peNaNO2 uye hydrochloric acid, uye inobva yaita Sandmeyer reaction pamberi peCu2Cl2 kuti iwane 2,4-dichloroluene. 3-Chloro-4-methylaniline nzira 3-chloro-4-methylaniline uye hydrochloric acid inowedzerwa kune inopindurwa kettle, NaNO2 aqueous solution inowedzerwa inodonha pa3～5℃, uye kuwedzera kunopedzwa mukati me2～3h ye diazotization Mushure me mhinduro, iyo diazotized liquid inowedzerwa kudonha kune hydrochloric acid solution ine Cu2Cl2 pa2-5 ° C kuita Sandmeyer reaction kuti iwane 2,4-dichloroluene. Pakati penzira dziri pamusoro apa, chloride inogadzirwa nekushandisa p-chlorotoluene uye o-chlorotoluene sezvinhu zvakasvibiswa zvine tsvina yakawanda uye ine zviputi zvakafanana. Izvo zvinodikanwa kushandisa yakakwirira-inoshanda kugadzirisa shongwe kuti iite chikamu kuti uwane zvinopfuura 98% ye2,4-dichloroluene. Idzi nzira mbiri dzakaoma kushanda, uye mutengo wekudyara wemidziyo wakakwira. Iyo 2,4-diaminotoluene nzira haina kukodzera kushandiswa kwemaindasitiri, uye nzira ye o-nitrotoluene uye 3-chloro-4-methylaniline nzira yekugadzirira 2,4-dichloroluene ine nheyo dzakafanana, uye zvose zvinoda diazotization uye Sandmeyer Mukupindura. , pane kuperevedza kwemvura yakasviba yakawanda. Nzira ye o-nitrotoluene inoshandiswa kugadzira 2-chloro-6-nitrotoluene, iyo inoderedzwa zvakare kuti iwane 2-chloro-6-aminotoluene, inova yakakosha yepakati pakugadzirwa kwemushonga wesora quinclorac.
