Isingeniso

I-N-Methylacetamide iyinhlanganisela yezinto eziphilayo. Iwuketshezi olungenambala oluncibilika emanzini kanye nezincibilikisi eziningi eziphilayo ezingeni lokushisa elilingana negumbi.

 

I-N-methylacetamide ivame ukusetshenziswa ku-organic synthesis njengesixazululi nesimaphakathi. I-N-methylacetamide ingasetshenziswa futhi njenge-ejenti eqeda amanzi emzimbeni, i-ammoniating agent, kanye ne-activator ye-carboxylic acid ekuphenduleni kwe-organic synthesis.

 

Ukulungiswa kwe-N-methylacetamide ngokuvamile kungatholakala ngokusabela kwe-acetic acid nge-methylamine. Isinyathelo esiqondile ukuphendula i-acetic acid ne-methylamine ngesilinganiso se-molar esingu-1:1 ngaphansi kwezimo ezifanele, bese kuba yi-distillation nokuhlanza ukuze kutholwe umkhiqizo oqondiwe.

 

Ulwazi lokuphepha: Umhwamuko we-N-methylacetamide ungacasula amehlo nendlela yokuphefumula, futhi unomphumela ocasulayo omncane lapho uthintana nesikhumba. Uma usebenzisa noma uphatha, kufanele kuthathwe izinyathelo zokuzivikela, njengokugqoka izibuko zokuzivikela, amagilavu ​​okuzivikela, njll. I-N-methylacetamide nayo inobuthi emvelweni, ngakho-ke kuyadingeka ukuhambisana nemithetho nemithethonqubo yokuvikela imvelo futhi unake. ukulahlwa kahle kwemfucuza. Lapho usebenzisa futhi ugcina, izinqubo ezifanele zokusebenza zokuphepha nemihlahlandlela yokusebenza kufanele kulandelwe.
