Tšebeliso
Dimethyl Disulfide (DMDS) ke motsoako oa lik'hemik'hale o nang le foromo ea C2H6S2. Ke mokelikeli o se nang 'mala o nang le monko o matla, o sa thabiseng. Tse ling tsa tšebeliso ea oona e ka sehloohong ke tsena:
1. Indastering ea peterole: DMDS e sebelisoa haholo e le setlolo se nang le sebabole ho hloekisoeng ha peterole. E thusa ho ntlafatsa katleho ea lits'ebetso tsa ho tlosa sebabole ka ho sebetsa e le mohloli oa sebabole. E ka arabela le li-oxide tsa tšepe holim'a li-catalyst tsa ho tlosa sebabole, ea ntlafatsa ts'ebetso ea tsona le botsitso, 'me ka hona ea ntlafatsa sekhahla sa ho tlosoa ha metsoako e nang le sebabole lihlahisoa tsa peterole.
2. Indastering ea lik'hemik'hale: Ke thepa ea bohlokoa bakeng sa ho kopanya metsoako e fapaneng e nang le sebabole sa tlhaho. Mohlala, e ka sebelisoa ho lokisa methanethiol, e sebelisoang hape tlhahisong ea chefo e bolaeang likokoanyana, meriana le lik'hemik'hale tse ling tse ntle. DMDS e ka boela ea sebelisoa ho kopanyeng metsoako e meng e nang le sebabole sa heterocyclic, e nang le lits'ebetso tsa bohlokoa tšimong ea ho kopanya lintho tse phelang.
3. E le sebolaya-dikokwana-hloko: Ka lebaka la chefo ea eona ho likokoanyana le likokoana-hloko, DMDS e ka sebelisoa e le sebolaya-dikokwana-hloko ho laola likokoanyana le li-fungus lijo-thollong tse bolokiloeng, matlong a polokelo le matlong a limela. E ka bolaea likokoanyana tse fapaneng le li-fungus ka katleho, e thusa ho sireletsa lihlahisoa tsa temo tse bolokiloeng le ho thibela ho ata ha mafu.
4. Lefapheng la di-elektroniki: DMDS e sebediswa indastering ya di-semiconductor bakeng sa ditshebetso tse itseng tse kang ho bewa ha mouoane wa dikhemikhale (CVD). E ka sebediswa ho bea difilimi tse tshesane tse nang le sebabole, tse nang le ditshebetso tlhahisong ya disebediswa tsa elektroniki tse kang di-transistors le di-sensor.
5. K'hemistring ea tlhahlobo: DMDS e ka sebelisoa e le reagent ea derivatization k'hemistring ea tlhahlobo. E ka arabela le lihlopha tse ling tse sebetsang ka har'a metsoako ea lintho tse phelang ho etsa li-derivatives tse nang le thepa e betere ea chromatographic kapa spectroscopic, e leng se nolofalletsang karohano le ho lemoha metsoako ena. Mohlala, e ka sebelisoa tlhahlobong ea mafura a acid le metsoako e meng ea lintho tse phelang ka chromatography ea khase - mass spectrometry (GC - MS).
Boloka le ho boloka
Nako ea ho boloka: Likhoeli tse 24 ho tloha letsatsing la tlhahiso ka har'a sephutheloana sa pele se sa buloang se bolokiloe sebakeng se pholileng se omileng se se nang khanya ea letsatsi, metsi.
Ntlo ea polokelo e nang le moea o kenang, Ho omisa mocheso o tlase, E arotsoe ho li-oxidant, li-acid.
