I-Methyl 2-bromomethyl-3-nitrobenzoate (CAS# 98475-07-1)

Isingeniso

I-Methyl 2-bromomethyl-3-nitrobenzoate.

Ikhwalithi:

1. Ukubukeka: uketshezi olungenambala noma okuqinile okucwebezelayo okumhlophe;

4. Ukuminyana: mayelana ne-1.6-1.7 g/ml;

5. Ukuncibilika: kuncibilika kuzincibilikisi zemvelo, njengotshwala, ama-ether nama-ketone.

Sebenzisa:

I-Methyl 2-bromomethyl-3-nitrobenzoate ivamise ukusetshenziswa njengendawo emaphakathi yezibulala-zinambuzane, ingasetshenziswa ekuhlanganiseni izibulala-zinambuzane ezifana ne-methyl besylsulfonylcarboxyl, futhi ingasetshenziswa njenge-synthetic intermediate ye-glyphosate.

Indlela:

I-Methyl 2-bromomethyl-3-nitrobenzoate ingalungiswa nge-chloromethylation kanye ne-nitrification. Izinyathelo eziqondile zimi kanje: i-methyl benzoate isabela nge-acetic acid ne-phosphorus trichloride ekushiseni okuphansi ukuze ithole i-methyl 2-chloromethylbenzoate; Bese, i-methyl 2-chloromethylbenzoate yethulwa eqenjini le-nitro ngokufaka i-nitrification ye-nitrate yomthofu ukunikeza i-methyl 2-bromomethyl-3-nitrobenzoate.

Ulwazi Lokuphepha:

1. I-Methyl 2-bromomethyl-3-nitrobenzoate iyasha ekushiseni okuphezulu kanye nelangabi elivulekile, ngakho izinga lokushisa eliphezulu kanye nelangabi elivulekile kufanele kugwenywe.

2. Gqoka izibuko zokuzivikela zamakhemikhali namagilavu ​​lapho usebenzisa ukugwema ukuthintana nesikhumba kanye nokuhogela amagesi.

4. Uma uyigcina, kufanele ivalwe futhi igcinwe kude nokushisa, umlilo kanye nama-oxidants.
