Nzira yekushandisa uye yekugadzira 2,4-Dichlorotoluene
Hunhu hwemakemikari: mvura isina ruvara uye inoonekera.
Shandisa:
1) Inoshandiswa semushonga wezvipembenene, madhayi nemishonga, inoshandiswa mukugadzira 2,4-dichlorobenzaldehyde, mishonga yakaita seadipine, buprofen, nezvimwewo.
2) 2,4-Dichlorotoluene chikamu chemishonga inouraya utachiona inonzi diniconazole nebenzylchlorotriazole, uye Chemicalbook ndiyo zvakare inoshandiswa pakugadzira 2,4-dichlorobenzaldehyde.
3) Zvinhu zvakagadzirwa nemakemikari, zvinoshandiswa muindasitiri yemishonga pakugadzira mishonga yekurwisa malaria, Adepine, uye kugadzira ventral acid. Zvinoshandiswa mumishonga yezvipembenene kugadzira 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, uye 2,4-dichlorobenzoic acid.

Kune nzira mbiri dzekugadzira dzekugadzira.
1. Nzira ye1.2,4-dichlorotoluene inoshandisa 2,4-diaminotoluene sezvinhu zvakabikwa, uye inowanikwa ne diazotization uye chlorination. Isa hydrochloric acid nemvura muhari ye reaction, pisa kusvika 50℃, nyungudutsa 2,4-diaminotoluene uchikurunga, wobva waisa hydrochloric acid ne cuprous chloride muhari, wedzera 1% sodium nitrite solution zvakaenzana muChemicalbook. Tembiricha inochengetwa pa60℃, mira yakamira kuti iraurwe, chigadzirwa chepasi checrude chinogezwa nemvura kusvika chave neutral, alkali inowedzerwa kualkali, wozogezwa nemvura kubvisa alkali, crude 2,4-dichlorotoluene inoparadzaniswa, uye chigadzirwa chakapedzwa chinonyungudutswa nemhepo. . Nzira ye2.3-chloro-4-toluidine inowanikwa ne diazotization reaction ne sodium nitrite, uye Sandmeyer reaction ne copper chloride.

2.Nzira yekugadzira uye nzira dzayo dzekugadzirira ndeinotevera. Munzira yeparachlorotoluene, p-chlorotoluene necatalyst ZrCl4 zvinoiswa mureactor, uye chlorine gasi rinoburitswa kuti riite chlorination reaction. Huwandu hwegesi yechlorine hunodzorwa kusvika kumagumo ereaction uye reaction inomiswa. Reactant inowanikwa ine 85.1% ye2,4-dichlorotoluene. Kana FeCl3 ikashandiswa secatalyst kuti iite chlorination reaction pa10 ～15℃ kusvika huwandu hwemhinduro hwava 1.025, chigadzirwa chacho chine 2,4-dichlorotoluene ne3,4-dichlorotoluene, uye chiyero chehukuru hwezvikamu zviviri i100:30. Mushure mekunge chlorination yapera, geza nemvura kusvika yasara, uye rapa ne10% NaOH solution pa100 ～110℃ kubvisa zvimwe tsvina. Chloride yakarapwa inogadziriswa uye inoparadzaniswa muchikamu chekugadzirisa chakanyanya kushanda (2,4-dichloro Toluene bp200°C, 3,4-dichlorotoluene bp207°C). Mugoho we2,4-dichlorotoluene ne3,4-dichlorotoluene waive 64.4% uye 19.8%, zvichiteerana. Ortho-chlorotoluene nzira ye o-chlorotoluene inoshandisa sulfuryl chloride se chlorinating agent kuita chlorination reaction pa142 ～196℃. Zvigadzirwa zvacho 2,4-dichlorotoluene ne2,3-dichlorotoluene, uye hazvina kugadziriswa. Kuumbwa kwezvinhu zvakagadzirwa 55%, 6%, uye 39%, zvichiteerana. Mushure mekudirwa (2,4-dichlorotoluene bp 200°C, 2,3-dichlorotoluene bp 207-208°C, o-chlorotoluene bp 157-159°C), 2,4-dichlorotoluene yakaparadzaniswa. Nzira yeOrtho-nitrotoluene Ortho-nitrotoluene inoiswa chlorine kana paine FeCl3 catalyst pa35～40℃. Kana huwandu hwe reactant hwasvika 1.320 (15℃), geza zvinhu kusvika zvanyatsojeka, uye reactant ine 15% yezvinhu zvisina kugadzirwa, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21%, uye 15% polychloride, mushure mekugadzirisa nekugadzirisa makristaro, Chemicalbook to 2-chloro-6-nitrotoluene. Kubuda kwe 4-chloro-2-nitrotoluene ne 4-chloro-2-nitrotoluene kuri 50% uye 30% zvichiteerana. 4-chloro-2-nitrotoluene inowanikwa ne hydrogenation reduction reaction uye steam distillation kuti iwane 4-chloro-2-amino. Toluene, diazotization uye kuwedzera CH2Cl2 yeSandmeyer reaction kuti iwane 2,4-dichlorotoluene. Nzira iyi inoshandiswa kugadzira 4-chloro-2-nitrotoluene inova chinhu chinobva pa2-chloro-6-nitrotoluene (inoshandiswa sechikamu chemushonga weherbicide quinclorac). 2,4-Diaminotoluene Nzira 2,4-Diaminotoluene inopinda mu diazotization reaction paine NaNO2 uye hydrochloric acid, uye yobva yaita Sandmeyer reaction paine Cu2Cl2 kuti iwane 2,4-dichlorotoluene. 3-Chloro-4-methylaniline nzira 3-chloro-4-methylaniline uye hydrochloric acid zvinowedzerwa mu reaction kettle, NaNO2 aqueous solution inowedzerwa ne dropwise pa 3～5℃, uye kuwedzera kunopedzwa mukati memaawa 2～3 e diazotization Mushure me reaction, diazotized liquid inowedzerwa ne dropwise kune hydrochloric acid solution ine Cu2Cl2 pa 2-5°C kuti iite Sandmeyer reaction kuti iwane 2,4-dichlorotoluene. Pakati penzira dziri pamusoro apa, chloride inogadzirwa nekushandisa p-chlorotoluene ne o-chlorotoluene sezvinhu zvisina kuchena ine tsvina yakawanda uye ine poindi dzakafanana dzekufashaira. Zvakakosha kushandisa matangi ekugadzirisa anoshanda zvakanyanya kuti aparadzanise kuti awane anopfuura 98% ye2,4-dichlorotoluene. Nzira mbiri idzi dzakaoma kushandisa, uye mari yekudyara michina yakakwira. Nzira ye2,4-diaminotoluene haina kukodzera kugadzirwa kwemaindasitiri, uye nzira ye o-nitrotoluene uye nzira ye 3-chloro-4-methylaniline yekugadzirira 2,4-dichlorotoluene dzine misimboti yakafanana, uye dzese dzinoda diazotization uye Sandmeyer. Mukupindura, pane kushomeka kwemvura yakawanda yakasviba. Nzira ye o-nitrotoluene inoshandiswa kugadzira pamwe chete 2-chloro-6-nitrotoluene, iyo inoderedzwa zvakanyanya kuti iwane 2-chloro-6-aminotoluene, inova chinhu chakakosha chekugadzira herbicide quinclorac.
