Isingeniso
I-2-Methyl-3-tetrahydrofuran mercaptan, evame ukwaziwa nge-MTST noma i-MTSH, inalezi zimpawu ezilandelayo:
Ukubukeka: Uketshezi olungenambala ukuya kokuphuzi olukhanyayo.
Iphunga: Inokunambitheka okukhethekile kwe-hydrogen sulfide.
Ukuminyana: cishe. 1.0 g/cm³.
Ukusetshenziswa kwayo okuyinhloko kungokulandelayo:
I-ejenti yokulungiselela uketshezi lwe-Ionic: I-MTST ingasetshenziswa njengesixazululi nesithasiselo sokulungiselela uketshezi lwe-ionic.
Ukusetshenziswa kwezimboni: I-MTST ivame ukusetshenziswa njenge-ejenti yokunciphisa kanye ne-chelating ezinqubweni zezimboni ezifana nokuhlanza insimbi, ukwelashwa kwendawo kanye ne-electroplating.
Indlela yokulungiselela ye-MTST:
Indlela evamile yokulungiselela iwukusabela i-methiophenol ngama-reagents afana ne-magnesium methyl bromide noma i-copper methyl bromide ku-tetrahydrofuran noma ezinye izinyibilikisi ezifanele ukuze kutholwe umkhiqizo oqondiwe.
Ulwazi Lokuphepha lwe-MTST:
Inobuthi obukhulu: I-MTST iyacasula futhi igqwalisa isikhumba, amehlo, nesistimu yokuphefumula, futhi kufanele kusetshenziswe izinto zokuzivikela ezifanele.
Okuvuthayo: I-MTST iwuketshezi oluvuthayo, futhi imithombo yomlilo namazinga okushisa aphezulu kufanele kugwenywe lapho igcinwa futhi isetshenziswa.
Gwema ukuchayeka isikhathi eside: Ukuchayeka isikhathi eside ku-MTST kungaholela ekubeni ushevu nezinye izinkinga zempilo, futhi ukuchayeka isikhathi eside kufanele kugwenywe ngangokunokwenzeka.
Isitoreji Nokuphatha: I-MTST kufanele igcinwe esitsheni esingangeni moya, kude nokushisa kanye nama-oxidants. Uketshezi olungcolile neziqukathi kufanele kulahlwe ngokuhambisana nemithetho yendawo.
Lapho usebenzisa futhi uphatha i-MTST, kubalulekile ukuqonda nokuthobela izinqubo nemithethonqubo yokusebenza yokuphepha efanele.
