Ukusetyenziswa
I-Dimethyl Disulfide (DMDS) yikhemikhali enefomyula i-C2H6S2. Lulwelo olungenambala olunevumba elibi nelingathandekiyo. Nazi ezinye zeendlela ezisetyenziswa ngayo:
1. Kwishishini lepetroleum: I-DMDS isetyenziswa kakhulu njengesongezelelo esiqulathe isalfur ekucoceni ipetroleum. Inceda ukuphucula ukusebenza kakuhle kweenkqubo zokususa isalfurization ngokusebenza njengomthombo wesalfur. Ingasabela kunye nee-metal oxides kumphezulu wee-catalysts zokususa isalfurization, iphucula umsebenzi wazo kunye nozinzo, ngaloo ndlela iphucula izinga lokususwa kweekhompawundi ezinesalfur kwiimveliso zepetroleum.
2. Kwishishini leekhemikhali: Sisixhobo esibalulekileyo sokwenziwa kweekhompawundi ezahlukeneyo zesulfure eziphilayo. Umzekelo, singasetyenziselwa ukulungiselela i-methanethiol, esetyenziswa ngakumbi ekuvelisweni kwee-pesticides, amayeza, kunye nezinye iikhemikhali ezintle. I-DMDS ingasetyenziswa nasekuvelisweni kweekhompawundi ezithile ze-heterocyclic ezine-sulfure, ezinezicelo ezibalulekileyo kwicandelo lokwenziwa kwezinto eziphilayo.
3. Njengesibulali-zinambuzane: Ngenxa yokuba inetyhefu kwizinambuzane nakwiintsholongwane, i-DMDS ingasetyenziswa njengesibulali-zinambuzane ukulawula izinambuzane kunye neefungi kwiinkozo ezigciniweyo, kwiindawo zokugcina ukutya, nakwiindawo zokugcina izityalo. Ingabulala ngempumelelo iintlobo ngeentlobo zezinambuzane kunye neefungi, inceda ekukhuseleni iimveliso zezolimo ezigciniweyo kwaye ithintele ukusasazeka kwezifo.
4. Kwicandelo le-elektroniki: I-DMDS isetyenziswa kwishishini le-semiconductor kwiinkqubo ezithile ezifana nokufakwa komphunga wekhemikhali (i-CVD). Ingasetyenziselwa ukufaka iifilimu ezincinci eziqulathe isalfure, ezinezicelo ekwenziweni kwezixhobo ze-elektroniki ezifana nee-transistors kunye nee-sensors.
5. Kwikhemistri yohlalutyo: I-DMDS ingasetyenziswa njenge-reagent yokuvelisa kwikhemistri yohlalutyo. Ingasabela namaqela athile asebenzayo kwiikhompawundi ze-organic ukwenza ii-derivatives ezineempawu ezingcono ze-chromatographic okanye ze-spectroscopic, nto leyo eyenza kube lula ukwahlula kunye nokufumanisa ezi khompawundi. Umzekelo, ingasetyenziswa kuhlalutyo lwee-fatty acids kunye nezinye iikhompawundi ze-organic nge-gas chromatography - mass spectrometry (GC - MS).
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
