METHYL 2 5-DICHLORONICOTINATE(CAS# 67754-03-4)
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-Methyl 2, iyinhlanganisela ye-organic enefomula yamakhemikhali C7H4Cl2NO2. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
- i-methyl 2, iwuketshezi olungenambala.
-Inephunga elimnandi elihlabayo.
-I-compound iyancibilika ku-solvent ye-organic efana ne-methanol noma i-dichloromethane.
-Indawo yokuncibilika kwayo icishe ibe ngu-43-47°C, futhi indawo yayo yokubila icishe ibe ngu-257-263°C.
Sebenzisa:
- i-methyl 2, evame ukusetshenziswa njengendawo yokwenziwa yezibulala-zinambuzane nezibulala-zinambuzane.
-Ingase futhi isetshenziselwe ukuhlanganisa ezinye izinhlanganisela ku-organic synthetic chemistry.
Indlela Yokulungiselela:
- i-methyl 2, ingalungiswa ngezinyathelo ezilandelayo:
1. Okokuqala, i-2,5-dichloronicotinic acid i-esterified nge-formic acid.
2. Ukusabela kuvame ukwenziwa ngaphansi kwezimo ezine-acidic, futhi i-esterifying agent, njengotshwala noma i-acid catalyst, yengezwa ukukhuthaza ukusabela.
3. Ngemuva kokuthi ukusabela kuqediwe, umkhiqizo ohlosiwe uyahlukaniswa futhi uhlanjululwe engxubeni yokusabela ngokukhishwa kwe-distillation noma isizinda.
Ulwazi Lokuphepha:
- i-methyl 2, iyinhlanganisela ecasulayo engase ibe nomthelela ocasulayo emehlweni, esikhumbeni kanye nolwelwesi lwamafinyila.
-Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu nezingubo zokuzivikela lapho uphatha futhi usebenzisa.
-Kufanele kube kude nomlilo kanye nezinga lokushisa eliphezulu ukuze kuvinjelwe ingozi yomlilo nokuqhuma.
-Lapho ugcina futhi uphatha, landela ngokuqinile izinqubo zokusebenza zokuphepha ukuze ugweme ukuxubana nokuxhumana nezinye izinto.
-Uma udliwe noma uhogelwe, funa usizo lwezokwelapha ngokushesha futhi unikeze ishidi ledatha yokuphepha noma ilebula yamakhemikhali.
