Ukusetshenziswa
I-Dimethyl Disulfide (DMDS) iyinhlanganisela yamakhemikhali enefomula i-C2H6S2. Iwuketshezi olungenambala olunephunga elinamandla nelingathandeki. Nazi ezinye zezindlela eziyinhloko zokusetshenziswa kwayo:
1. Embonini kaphethiloli: I-DMDS isetshenziswa kabanzi njengesithasiselo esiqukethe i-sulfur ekuhlanzeni uphethiloli. Isiza ekuthuthukiseni ukusebenza kahle kwezinqubo zokususa i-sulfurization ngokusebenza njengomthombo we-sulfur. Ingasabela nama-oxide ensimbi ebusweni be-catalysts yokususa i-sulfurization, ithuthukise umsebenzi wayo kanye nokuqina kwayo, ngaleyo ndlela ithuthukise izinga lokususwa kwamakhemikhali aqukethe i-sulfur emikhiqizweni kaphethiloli.
2. Embonini yamakhemikhali: Iyinto ebalulekile yokwenziwa kwamakhemikhali ahlukahlukene aqukethe i-sulfur ephilayo. Isibonelo, ingasetshenziswa ukulungiselela i-methanethiol, esetshenziswa futhi ekukhiqizweni kwezibulala-zinambuzane, imithi, kanye namanye amakhemikhali amahle. I-DMDS ingasetshenziswa futhi ekuhlanganisweni kwamakhemikhali athile aqukethe i-sulfur e-heterocyclic, anezicelo ezibalulekile emkhakheni wokwenziwa kwezinto eziphilayo.
3. Njengesithako sokufutha: Ngenxa yobuthi bayo ezinambuzaneni nasezilwanyaneni ezincane, i-DMDS ingasetshenziswa njengesithako sokufutha ukulawula izinambuzane nesikhunta ezinhlamvini ezigciniwe, ezindaweni zokugcina impahla kanye nasezindlini zokugcina izitshalo. Ingabulala ngempumelelo izinambuzane nesikhunta ezahlukahlukene, isize ekuvikeleni imikhiqizo yezolimo egciniwe futhi ivimbele ukusabalala kwezifo.
4. Emkhakheni we-elekthronikhi: I-DMDS isetshenziswa embonini ye-semiconductor ezinqubweni ezithile ezifana nokufakwa kwe-chemical vapor (CVD). Ingasetshenziswa ukufaka amafilimu amancane aqukethe i-sulfur, anezinhlelo zokusebenza ekwakhiweni kwamadivayisi kagesi afana nama-transistors nama-sensor.
5. Kumakhemikhali okuhlaziya: I-DMDS ingasetshenziswa njenge-reagent yokususa i-athomu kumakhemikhali okuhlaziya. Ingasabela namanye amaqembu asebenzayo kuma-organic compounds ukuze yakhe ama-derivatives anezakhiwo ezingcono ze-chromatographic noma ze-spectroscopic, okwenza kube lula ukuhlukaniswa nokutholakala kwala ma-compounds. Isibonelo, ingasetshenziswa ekuhlaziyweni kwama-fatty acids kanye namanye ama-organic compounds nge-gas chromatography - mass spectrometry (GC - MS).
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
