Mawu Oyamba
Methyloxaloyl chloride ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
Methyloxaloyl chloride ndi madzi opanda mtundu komanso onunkhira. Ndi chinthu cholimba cha acidic chomwe chimagwirizana ndi madzi kupanga formic acid ndi oxalic acid. Methyl oxaloyl chloride imakhala ndi mphamvu ya nthunzi yambiri komanso kusakhazikika, ndipo nthawi yomweyo imakhala ndi corrosiveness yamphamvu.
Gwiritsani ntchito:
Methyl oxaloyl chloride ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic. Oxalyl methyl chloride angagwiritsidwe ntchito zosiyanasiyana organic kaphatikizidwe zimachitikira, monga acylation reaction, esterification reaction ndi carboxylic acid otumphukira synthesis.
Njira:
Kukonzekera kwa methyl oxaloyl chloride nthawi zambiri kumagwiritsa ntchito benzoic acid ngati zopangira, ndipo oxaloyl chloroformimide imapangidwa pansi pa zochita za thionyl chloride, kenako ndi hydrolyzed kuti ipeze methyl oxaloyl chloride.
Zambiri Zachitetezo:
Methyloxaloyl chloride imakwiyitsa kwambiri komanso ikuwononga, ndipo imatha kuyambitsa kuyaka kwamankhwala pakhungu ndi maso. Kulumikizana mwachindunji kuyenera kupewedwa panthawi yogwiritsira ntchito ndi kusunga. Zovala zodzitchinjiriza zoyenera, zovala zoteteza maso ndi zida zoteteza kupuma ziyenera kuvalidwa zikagwiritsidwa ntchito. Gwirani ntchito pamalo olowera mpweya wabwino ndipo pewani kutulutsa nthunzi yake. Posunga, ziyenera kusungidwa mosiyana ndi zotulutsa zotulutsa, zidulo ndi zamchere kuteteza moto ndi ngozi.
