Mawu Oyamba
Methyl 2-bromomethyl-3-nitrobenzoate.
Ubwino:
1. Maonekedwe: madzi opanda mtundu kapena oyera crystalline olimba;
4. Kachulukidwe: pafupifupi 1.6-1.7 g / ml;
5. Kusungunuka: kusungunuka mu zosungunulira za organic, monga ma alcohols, ethers ndi ketones.
Gwiritsani ntchito:
Methyl 2-bromomethyl-3-nitrobenzoate nthawi zambiri amagwiritsidwa ntchito ngati mankhwala ophera tizilombo, amatha kugwiritsidwa ntchito popanga mankhwala ophera tizilombo monga methyl besylsulfonylcarboxyl, komanso angagwiritsidwe ntchito ngati chopangira chapakatikati cha glyphosate.
Njira:
Methyl 2-bromomethyl-3-nitrobenzoate ikhoza kukonzedwa ndi chloromethylation ndi nitrification. Masitepe enieni ndi awa: methyl benzoate imachitidwa ndi acetic acid ndi phosphorous trichloride pa kutentha kochepa kuti ipeze methyl 2-chloromethylbenzoate; Kenako, methyl 2-chloromethylbenzoate imalowetsedwa mu gulu la nitro ndi nitrification wa lead nitrate kuti apereke methyl 2-bromomethyl-3-nitrobenzoate.
Zambiri Zachitetezo:
1. Methyl 2-bromomethyl-3-nitrobenzoate imatha kuyaka pa kutentha kwakukulu ndi moto wotseguka, kotero kutentha kwakukulu ndi moto wotseguka ziyenera kupeŵedwa.
2. Valani magalasi oteteza mankhwala ndi magolovesi pamene mukugwiritsa ntchito kupewa kukhudzana ndi khungu ndi kupuma mpweya.
4. Posunga, iyenera kusindikizidwa ndi kusungidwa kutali ndi kutentha, moto ndi okosijeni.
