Isingeniso
I-Methyloxaloyl chloride iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
I-Methyloxaloyl chloride iwuketshezi olungenambala olunephunga elimnandi. Kuyinto eqinile ene-asidi esabela emanzini ukuze yakhe i-formic acid ne-oxalic acid. I-Methyl oxaloyl chloride inomfutho we-vapor ophezulu kanye nokuguquguquka, futhi ngesikhathi esifanayo inokugqwala okuqinile.
Sebenzisa:
I-Methyl oxaloyl chloride iyingxenye ebalulekile ye-organic synthesis. I-Oxalyl methyl chloride ingasetshenziselwa ukusabela okuhlukahlukene kwe-organic synthesis, njengokusabela kwe-acylation, ukusabela kwe-esterification kanye ne-carboxylic acid derivative synthesis.
Indlela:
Ukulungiswa kwe-methyl oxaloyl chloride kuvame ukusebenzisa i-benzoic acid njengempahla eluhlaza, futhi i-oxaloyl chloroformimide ikhiqizwa ngaphansi kwesenzo se-thionyl chloride, bese i-hydrolyzed ukuze kutholwe i-methyl oxaloyl chloride.
Ulwazi Lokuphepha:
I-Methyloxaloyl chloride iyacasula kakhulu futhi iyagqwala, futhi ingabangela ukushiswa kwamakhemikhali lapho ithinta isikhumba namehlo. Ukuxhumana okuqondile kufanele kugwenywe ngesikhathi sokusetshenziswa nokugcinwa. Amagilavu okuvikela afanelekile, izingubo zamehlo ezivikelayo kanye nempahla yokuvikela ukuphefumula kufanele kugqokwe lapho kusetshenziswa. Isebenza endaweni engenawo umoya futhi ugweme ukuhogela umhwamuko wayo. Lapho igcinwa, kufanele igcinwe ngokuhlukana nama-oxidants, ama-asidi nama-alkali ukuvimbela imililo nezingozi.
