Intshayelelo
I-S-methyl thioacetate, ekwabizwa ngokuba yi-methyl thioacetate.
Umgangatho:
I-S-methyl thioacetate lulwelo olungenambala kunye nevumba elibukhali elibukhali. Iyanyibilika kwizinyibilikisi ezininzi ze-organic ezifana ne-alcohol, ii-ethers, kunye ne-aromatics.
Sebenzisa:
I-S-methyl thioacetate isetyenziswa ikakhulu kwi-vulcanization kunye ne-esterification reactions kwi-organic synthesis.
Indlela:
I-S-methyl thioacetate inokufumaneka ngokuphendula kwe-methyl acetate kunye nesulfure phantsi kweemeko ze-alkaline. Isinyathelo esithile kukusabela i-methyl acetate kunye nesisombululo sesulfure ye-alkali, kwaye emva koko i-distill kwaye ihlambulule imveliso ukuze ufumane imveliso.
Ulwazi ngoKhuseleko:
I-S-methyl thioacetate iyacaphukisa kwaye kufuneka igweme ukudibanisa ngqo nolusu kunye namehlo. Ngexesha lokusetyenziswa, kufuneka kuthathelwe ingqalelo amanyathelo okukhusela, njengokugqoka iiglasi zokukhusela kunye neiglavu. Xa ugcina kwaye uphatha le khompawundi, indawo enomoya opholileyo kufuneka igcinwe kwaye igcinwe kude nokutshisa kunye ne-oxidants. Kwimeko yokuvuza okanye iingozi, kufuneka zisuswe ngexesha kwaye amanyathelo afanelekileyo kaxakeka kufuneka athathwe. Xa usebenzisa le ngqungquthela, iinkqubo ezifanelekileyo zokusebenza zokhuseleko kufuneka ziqwalaselwe.
