Intshayelelo
I-Methyl 2-bromomethyl-3-nitrobenzoate.
Umgangatho:
1. Imbonakalo: ulwelo olungenambala okanye olumhlophe oluqinileyo lwekristale;
4. Ubuninzi: malunga ne-1.6-1.7 g / ml;
5. I-Solubility: i-solubility kwi-solvents ye-organic, efana ne-alcohol, i-ethers kunye ne-ketones.
Sebenzisa:
I-Methyl 2-bromomethyl-3-nitrobenzoate isoloko isetyenziswa njengendawo ephakathi yesibulali-zinambuzane, ingasetyenziswa ekudibaneni kwezibulali-zinambuzane ezifana ne-methyl besylsulfonylcarboxyl, kwaye inokusetyenziswa njenge-synthetic intermediate ye-glyphosate.
Indlela:
I-Methyl 2-bromomethyl-3-nitrobenzoate ingalungiswa nge-chloromethylation kunye ne-nitrification. Amanyathelo athile alandelayo: i-methyl benzoate iphendulwa nge-acetic acid kunye ne-phosphorus trichloride kwiqondo lokushisa eliphantsi ukufumana i-methyl 2-chloromethylbenzoate; Emva koko, i-methyl 2-chloromethylbenzoate ifakwe kwiqela le-nitro nge-nitrification ye-nitrate ye-lead ukunika i-methyl 2-bromomethyl-3-nitrobenzoate.
Ulwazi ngoKhuseleko:
1. I-Methyl 2-bromomethyl-3-nitrobenzoate inokutsha kwiqondo lokushisa eliphezulu kunye nomlilo ovulekileyo, ngoko ukushisa okuphezulu kunye nomlilo ovulekileyo kufuneka kugwenywe.
2. Gqoka iiglasi zokukhusela iikhemikhali kunye neiglavu xa usebenzisa ukuphepha ukudibanisa nolusu kunye nokuphefumla iigesi.
4. Xa ugcina, kufuneka itywinwe kwaye igcinwe kude nobushushu, umlilo kunye ne-oxidants.
