Nhanganyaya
Methyloxaloyl chloride ndeye organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
Methyloxaloyl chloride imvura isina ruvara uye inonhuwa. Chinhu chakasimba chine acidic chinopindirana nemvura kuita formic acid uye oxalic acid. Methyl oxaloyl chloride ine high vapor pressure uye volatility, uye panguva imwechete ine corrosiveness yakasimba.
Shandisa:
Methyl oxaloyl chloride yakakosha yepakati mune organic synthesis. Oxalyl methyl chloride inogona kushandiswa kune akasiyana organic synthesis maitiro, senge acylation reaction, esterification reaction uye carboxylic acid derivative synthesis.
Nzira:
Kugadzirira kwemethyl oxaloyl chloride kunowanzo shandisa benzoic acid seyakagadzirwa, uye oxaloyl chloroformimide inogadzirwa pasi pekuita kwe thionyl chloride, uyezve hydrolyzed kuti iwane methyl oxaloyl chloride.
Zvekuchengetedza
Methyloxaloyl chloride inoshatisa zvakanyanya uye inoparadza, uye inogona kukonzera kupisa kwemakemikari kunosangana neganda nemeso. Kubata kwakananga kunofanira kudziviswa panguva yekushandisa uye kuchengetedza. Magirovhosi ekudzivirira akakodzera, ziso rekudzivirira uye midziyo yekudzivirira yekufema inofanirwa kupfekwa kana ichishandiswa. Shanda munzvimbo ine mhepo inofefetera uye dzivisa kufemesa mhute dzayo. Paunenge uchichengeta, inofanira kuchengetwa zvakasiyana kubva kune oxidants, acids uye alkali kudzivirira moto uye njodzi.
