Amfani
Dimethyl Disulfide (DMDS) wani sinadari ne mai suna C2H6S2. Ruwa ne mara launi tare da ƙamshi mai ƙarfi da ban sha'awa. Ga wasu daga cikin manyan amfaninsa:
1. A fannin man fetur: Ana amfani da DMDS sosai a matsayin wani abu mai ɗauke da sulfur a cikin tace man fetur. Yana taimakawa wajen inganta ingancin hanyoyin desulfurization ta hanyar aiki a matsayin tushen sulfur. Yana iya amsawa da ƙarfe oxides a saman abubuwan da ke haɓaka desulfurization, yana haɓaka ayyukansu da kwanciyar hankali, don haka yana inganta yawan cirewar mahaɗan da ke ɗauke da sulfur a cikin kayayyakin man fetur.
2. A masana'antar sinadarai: Yana da matukar muhimmanci wajen hada sinadarai daban-daban masu dauke da sinadarin sulfur. Misali, ana iya amfani da shi wajen shirya methanethiol, wanda ake amfani da shi wajen samar da magungunan kashe kwari, magunguna, da sauran sinadarai masu kyau. Haka kuma ana iya amfani da DMDS wajen hada wasu sinadarai masu dauke da sinadarin sulfur, wadanda ke da amfani mai mahimmanci a fannin hada sinadarai masu dauke da sinadarin.
3. A matsayin mai kashe kwari: Saboda gubarsa ga kwari da ƙananan halittu, ana iya amfani da DMDS a matsayin mai kashe kwari don sarrafa kwari da fungi a cikin hatsi da aka adana, rumbunan ajiya, da gidajen kore. Yana iya kashe kwari da fungi iri-iri yadda ya kamata, yana taimakawa wajen kare kayayyakin noma da aka adana da kuma hana yaɗuwar cututtuka.
4. A fannin kayan lantarki: Ana amfani da DMDS a masana'antar semiconductor don wasu ayyuka kamar adana tururin sinadarai (CVD). Ana iya amfani da shi don ajiye sulfur - wanda ke ɗauke da siririn fim, waɗanda ke da amfani wajen ƙera na'urorin lantarki kamar transistors da firikwensin.
5. A cikin ilmin sunadarai na nazari: Ana iya amfani da DMDS a matsayin maganin cirewa a cikin ilmin sunadarai na nazari. Yana iya amsawa da wasu ƙungiyoyi masu aiki a cikin mahallin halitta don samar da abubuwan da suka samo asali tare da ingantattun halayen chromatographic ko spectroscopic, wanda ke sauƙaƙa rabuwa da gano waɗannan mahaɗan. Misali, ana iya amfani da shi wajen nazarin fatty acids da sauran mahaɗan halitta ta hanyar amfani da gas chromatography - mass spectrometry (GC - MS).
Ajiyewa da adanawa
Rayuwar shiryayye: Watanni 24 daga ranar ƙera shi a cikin marufi na asali wanda ba a buɗe ba, an adana shi a wuri mai sanyi da bushewa, ba tare da hasken rana kai tsaye ba, ko ruwa.
Ma'ajiyar iska, Busar da ƙananan zafin jiki, An raba shi da sinadarai masu guba, acid.
