I-Methyl 5-chloro-6-methoxynicotinate (CAS# 220656-93-9)

Isingeniso

I-Methyl 5-chloro-6-methoxynicotinate iyinhlanganisela yezinto eziphilayo.

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala kuya kokuphuzi okuphaphathekile

- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-ether ne-methylene chloride

Sebenzisa:

- I-Methyl 5-chloro-6-methoxynicotinate iyinhlanganisela ebalulekile ephakathi enezinhlobonhlobo zezinhlelo zokusebenza ocwaningweni nasekulungiseleleni izinto eziphilayo.

Indlela:

I-Methyl 5-chloro-6-methoxynicotinate ingahlanganiswa ngezinyathelo ezilandelayo:

I-6-Methoxynicotinamide ihlanganiswa ngokusabela i-pyridine-3-carboxylic acid nge-methanol ngaphansi kwezimo ezifanele.

I-6-Methoxynicotinamide isabela ngesulfure chloride ukuze yakhe i-5-chloro-6-methoxynicotinamide.

Ngaphansi kwezimo ze-alkaline, i-5-chloro-6-methoxynicotinamide iguqulelwa ku-methyl 5-chloro-6-methoxynicotinate ngokusabela kwe-methanol esterification.

Ulwazi Lokuphepha:

I-Methyl 5-chloro-6-methoxynicotinate ngokuvamile iphephile ngokuphathwa kahle nokusetshenziswa, kodwa okulandelayo kusabalulekile ukuqaphela:

- Le nhlanganisela ingaba yingozi emvelweni futhi ukukhululwa kwayo endaweni yemvelo kufanele kugwenywe.

- Izinto zokuzivikela ezifanelekile ezifana namagilavu ​​zelabhu, izibuko, nezingubo zokuzivikela kufanele zisetshenziswe ngesikhathi sokuphatha.

- Gwema ukuthintana ngqo nesikhumba namehlo.

- Lapho ugcina futhi usebenzisa, landela izimiso zokuphatha amakhemikhali eziphephile futhi uzigcine zikude nezinto ezivuthayo nemithombo yokushisa.

- Le nhlanganisela ivinjelwe ukusetshenziswa ngabachwepheshe noma ngaphansi kokuqondisa okufanele.
