Intshayelelo
I-Methyl thioethyl S-acid branyl. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methyl thioethyl thioS-acid furfur:
Umgangatho:
I-Methyl thioethyl S-fufrate ngulwelo olungenambala kunye nencasa ekhethekileyo ye-methyl sulfate. Iyanyibilika kwizinyibilikisi zendalo ezifana neealkoholi, iiketones, kunye ne-ethers, kodwa ayinyibiliki emanzini.
Sebenzisa:
I-Methyl thioethyl S-furfur isetyenziswa ngokubanzi kwintsimi ye-organic synthesis. Ingasetyenziswa njenge-reagent yeempendulo ezahlukeneyo ze-organic synthesis, ezifana ne-carbonylation ye-amines, i-esterification kunye ne-acylation ye-alcohol, njl njl.
Indlela:
Ukulungiswa kwe-methyl thioethyl S-acid furfur idla ngokufunyanwa ngokusabela kwekhabhoni disulfide nge-methyl chloroacetate. Indlela ethile yokulungiselela yile ndlela ilandelayo: i-carbon disulfide iyancipha ngokukhawuleza kwi-methyl chloroacetate emanzini e-ice, kwaye isisombululo sokuphendula sishukunyiswa ngexesha elifanayo. Emva kokuba impendulo igqityiwe, isisombululo sokusabela songezwa kwisisombululo se-sodium chloride egcweleyo, kwaye emva koko i-organic layer ikhutshwe kwaye yomiswe nge-anhydrous sodium chloride. I-Methyl thioethyl S-acid furfur ifumaneka ngokuxutywa kwe-distillation.
Ulwazi ngoKhuseleko:
I-Methyl thioethyl S-furfur sisinyibilikisi se-organic kunye nevumba elimnandi kwaye kufuneka igwenywe xa isetyenziswa. Xa usebenza, kufuneka kunxitywe izixhobo ezifanelekileyo zokukhusela ezifana neeglasi zokukhusela kunye neeglavu. Kufuneka igcinwe kwindawo epholileyo, eyomileyo, nengena umoya kakuhle, kude nendawo yokutshisa kunye ne-oxidizers, ukunqanda umlilo kunye nokudubula. Ukusetyenziswa kunye nokugcinwa kwayo nayiphi na imichiza, kubalulekile ukulandela iindlela ezifanelekileyo zokuphatha ngokukhuselekileyo.
