Umsebenzi
I-Dimethyl Diskulfide (DMDS) iyindawo yamakhemikhali ngefomula C2H6S2. Kuwuketshezi olungenamibala ngephunga elinamandla, elingathandeki. Nazi ezinye zezinto zalo eziphambili:
1. Embonini kaphethiloli: Ama-DMDs asetshenziswa kabanzi njengesibabule - aqukethe isengezo ekucoculweni kwe-petroleum. Kuyasiza ukuthuthukisa ukusebenza kwezinqubo zokusungula ukusungula ngokwenza njengomthombo we-sulfur. Kungasabela ngo-oxides wensimbi ebusweni be-catalysts yokususela, ukuthuthukisa umsebenzi wabo kanye nokuqina, futhi ngaleyo ndlela kuthuthukise izinga lokususa lesibabule - eliqukethe imikhiqizo kaphethiloli.
2. Embonini yamakhemikhali: Kuyizinto ezibalulekile eziluhlaza zokuhlanganiswa kwezibulfur ezihlukile ze-organic - eziqukethe amakhompiyutha. Isibonelo, lingasetshenziswa ukulungiselela i-methanethiol, elisetshenziswe futhi ekukhiqizweni kwezibulala-zinambuzane, amakhamishini, namanye amakhemikhali amahle. Ama-DMDs nawo angasetshenziswa ekuhlanganiseni kwesibabule esithile - aqukethe amakhompiyutha we-heterocyclic, anezicelo ezibalulekile emkhakheni we-organic synthesis.
I-3. Njenge-fumigant: Ngenxa yobuthi bayo ezinambuzaneni nama-microorganisms, ama-DMDs angasetshenziswa njenge-fumigant ukulawula izinambuzane kanye nezindawo zokugcina izimpahla ezigciniwe. Kungabulala ngempumelelo izinambuzane ezahlukahlukene kanye nesikhunta, sisize ukuvikela imikhiqizo yezolimo egciniwe futhi ivikele ukusakazeka kwezifo.
I-4. Ensimini ye-elekthronikhi: Ama-DMDs asetshenziswa embonini ye-semiconductor ngezinqubo ezithile ezinjenge-Chemical VAPOR Deposition (CVD). Ingasetshenziswa ukufaka i-sulphur - equkethe amafilimu amancanyana, aqukethe izicelo ekwabiweni kwamadivayisi we-elekthronikhi anjenge-transistors nezinzwa.
5. Kumakhemikhali wokuhlaziya: Ama-DMDs angasetshenziswa njenge-reagent yokutholwa kumakhemikhali wokuhlaziya. Kungasabela ngamaqembu athile asebenzayo kumakhompiyutha ezi-organic ukwakha ama-derivatives anezakhiwo ezingcono ze-chromatographic noma ama-spectroscopic, okwenza ukuhlukaniswa nokutholwa kwalezi zinhlaka. Isibonelo, ingasetshenziswa ekuhlaziyweni kwama-fatty acids kanye nezinye izinhlanganisela ze-organic yigesi i-chromatography - I-Mass Spectrometry (GC - MS).
Gcina futhi ugcine
I-Shelf Life: Inyanga engama-24 kusukela ngosuku lokwenziwa ekuphaketheni kwasekuqaleni okungavunyelwe okugcinwe endaweni epholile eyomile ngaphandle kokukhanya kwelanga, amanzi.
I-Warehouse evutha umoya, ukomisa okushisa okuphansi, okuhlukaniswe nama-oxidants, ama-acid.
