2,4-Dichlorotoluene faʻaaogaina ma metotia faʻapipiʻi
O mea tau vaila'au: vai e leai ni lanu ma manino.
Fa'aaogā:
1) Faʻaaogaina e pei o vailaʻau faʻasaina, vali ma vailaʻau, faʻaaogaina i le gaosiga o le 2,4-dichlorobenzaldehyde, vailaʻau e pei o adipine, buprofen, ma isi.
2) 2,4-Dichlorotoluene o se vaeluagalemu o le bactericides diniconazole ma benzylchlorotriazole, ma Chemicalbook foi o le mea mataʻina mo le sauniuniga o le 2,4-dichlorobenzaldehyde.
3) Organic synthetic raw material, faʻaaogaina i le falemaʻi falemaʻi mo le gaosiga o vailaʻau faʻamaʻi, Adepine, ma le faʻaogaina o le ventral acid. Fa'aaogaina i vaila'au fa'asaina e gaosia ai le 2,4-dichlorobenzyl chloride, 2,4-dichlorobenzoyl chloride, ma le 2,4-dichlorobenzoic acid.

E lua auala faʻapipiʻi mo metotia gaosiga.
1. O le 1.2,4-dichlorotoluene auala e faʻaaogaina ai le 2,4-diaminotoluene e fai ma mea mata, ma maua mai i le diazotization ma le chlorination. Tuʻu le vailaʻau hydrochloric ma le vai i totonu o le ulo tali, vevela i le 50 ℃, faʻamavae le 2,4-diaminotoluene i lalo o le faʻavevesi, ona tuʻu lea o le hydrochloric acid ma le cuprous chloride i totonu o le ulo, faʻaopopo le 1% sodium nitrite solution tutusa i totonu o Chemicalbook, O le vevela e tausia i le e tusa ma le 60 ℃, tu pea mo le faʻapipiʻiina, o le oloa maualalo maualalo e fufulu i le vai seia oʻo ina le tutusa, faʻaopoopo le alkali i le alkali, ona fufulu lea i le vai e aveese ai le alkali, o le 2,4-dichlorotoluene mama ua vavae ese, ma le oloa mae'a o le ausa fa'amama. . O le auala 2.3-chloro-4-toluidine e maua i le diazotization reaction with sodium nitrite, ma Sandmeyer reaction with copper chloride.

2.Ole auala ole gaosiga ma ona auala sauniuni e fa'apea. I le auala parachlorotoluene, o le p-chlorotoluene ma le faʻamalosi ZrCl4 e tuʻuina i totonu o le reactor, ma faʻamalo le kasa chlorine e faʻatino ai le gaioiga o le chlorination. Ole aofa'i ole kasa chlorine e pulea e o'o ile fa'ai'uga ole tali ma taofi le tali. O le reactant na maua e aofia ai le 85.1% o le 2,4-dichlorotoluene. Afai o le FeCl3 o loʻo faʻaaogaina e fai ma faʻamalosi e faʻataunuʻu ai le chlorination i le 10 ~ 15 ℃ seia oʻo i le maualuga o le vaifofo o le 1.025, o le oloa e aofia ai le 2,4-dichlorotoluene ma le 3,4-dichlorotoluene, ma le fua faatatau o le lua. vaega o le 100:30 . A uma le chlorination, fufulu i le vai i le soli, ma togafitia i le 10% NaOH solution ile 100～110℃ e aveese ai isi mea leaga. O le chloride ua togafitia e faʻasaʻo ma vavae ese i totonu o se olo faʻasaʻo maualuga (2,4-dichloro Toluene bp200 ° C, 3,4-dichlorotoluene bp207 ° C). O fua o le 2,4-dichlorotoluene ma le 3,4-dichlorotoluene e 64.4% ma le 19.8%, i le faasologa. Ole Ortho-chlorotoluene auala ole-chlorotoluene e fa'aogaina ai le sulfuryl chloride e fai ma sui ole chlorinating e fa'atino ai le fa'a'ai ole chlorination ile 142～196℃. O oloa o le 2,4-dichlorotoluene ma le 2,3-dichlorotoluene, ma le le faʻaalia O le tuʻufaʻatasia o mea mataʻutia o le 55%, 6%, ma le 39%, i le faasologa. Ina ua uma ona fa'amama (2,4-dichlorotoluene bp 200°C, 2,3-dichlorotoluene bp 207-208°C, o-chlorotoluene bp 157-159°C), 2,4-dichlorotoluene na vavae'ese. Ortho-nitrotoluene auala Ortho-nitrotoluene e chlorinated i le i ai o le FeCl3 catalyst i le 35～40℃. Pe a oʻo i le 1.320 (15 ℃) le faʻatusatusaga o le reactant, fufulu le mea e le tutusa, ma o le reactant o loʻo i ai le 15% o mea mata, 2-chloro-6-nitrotoluene 49%, 4-chloro-2-nitrotoluene 21% , ma le 15% polychloride, pe a uma le faʻasaʻoina ma le faʻamaʻiina o togafitiga, o le Chemicalbook i le 2-chloro-6-nitrotoluene O fua o le 4-chloro-2-nitrotoluene ma le 4-chloro-2-nitrotoluene e 50% ma le 30%. E maua le 4-chloro-2-nitrotoluene e ala i le fa'aitiitiga o le hydrogenation ma le fa'amama ausa e maua ai le 4-chloro-2-amino. Toluene, diazotization ma faaopoopo CH2Cl2 mo Sandmeyer tali e maua ai le 2,4-dichlorotoluene. O le metotia e faʻaaogaina e gaosia ai le 4-chloro-2-nitrotoluene o se mea faʻapipiʻi mai le 2-chloro-6-nitrotoluene (faʻaaogaina e fai ma sui o le herbicide quinclorac). 2,4-Diaminotoluene Metotia 2,4-Diaminotoluene faia diazotization tali i le i ai o le NaNO2 ma hydrochloric acid, ona faia ai lea o Sandmeyer tali i luma o Cu2Cl2 e maua 2,4-dichlorotoluene. 3-Chloro-4-methylaniline auala 3-chloro-4-methylaniline ma hydrochloric acid ua faaopoopo i le ulo tali, NaNO2 vai vai e faaopoopo i lalo i lalo i le 3 ~ 5 ℃, ma le faʻaopoopoga e maeʻa i totonu ole 2 ~ 3h mo le diazotization A maeʻa le tali, o le vai diazotized ua faaopoopo dropwise i se vaifofo acid hydrochloric o loo i ai Cu2Cl2 i le 2-5°C e faatino Sandmeyer tali e maua 2,4-dichlorotoluene. Faatasi ai ma metotia o loʻo taʻua i luga, o le chloride e gaosia e ala i le faʻaaogaina o le p-chlorotoluene ma le o-chlorotoluene e pei o mea mataʻutia o loʻo i ai le tele o mea le mama ma e tutusa lelei mea e faʻafefe ai. E manaʻomia le faʻaogaina o olo faʻasaʻo maualuga e faʻavasegaina e maua ai le sili atu i le 98% o le 2,4-dichlorotoluene. O nei auala e lua e faigata ona faʻaogaina, ma o le tau faʻafaigaluegaina o meafaigaluega e maualuga. O le 2,4-diaminotoluene auala e le talafeagai mo alamanuia, ma o le o-nitrotoluene auala ma le 3-chloro-4-methylaniline auala e saunia ai le 2,4-dichlorotoluene e tutusa mataupu faavae, ma e manaomia uma le diazotization ma Sandmeyer I le tali. , o loʻo i ai se faʻaletonu o le tele o vai leaga. O le auala o-nitrotoluene e faʻaaogaina e faʻapipiʻi ai le 2-chloro-6-nitrotoluene, lea e faʻaititia atili e maua ai le 2-chloro-6-aminotoluene, o se mea taua tele mo le gaosiga o le herbicide quinclorac.
