Amfani
Dimethyl disulfide (DMDs) fili ne mai guba tare da dabarar C2h6s2. Ruwa ne mai launi mai launi mai ƙarfi, wari mara dadi. Anan akwai wasu amfaninta:
1. A cikin masana'antar man fetur: DMDs ana amfani dashi azaman sulfur - wanda ya ƙunshi ƙari a cikin sake fasalin petrooleum. Yana taimaka wajen inganta ingancin hanyoyin aiwatar da matakai ta hanyar aiki a matsayin tushen sulfur. Zai iya amsawa da ƙarfe na ƙarfe a saman mai kula da assulfuritization, haɓaka ayyukan su da kwanciyar hankali, kuma don haka inganta adadin ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar cuta.
2. A cikin masana'antar sunadarai: ita ce muhimmancin albarkatun ƙasa don haɗarin nau'ikan nau'ikan nau'ikan ƙwayar cuta - waɗanda ke ɗauke da mahadi. Misali, ana iya amfani dashi don shirya methane', wanda aka sake amfani dashi a cikin samar da magungunan kashe qwari, da sauran sunadarai masu kyau. Hakanan za'a iya amfani da DMDS a cikin tsarin rubutu na wasu sulfur - wanda ya ƙunshi mahaɗan heeterocyclic, waɗanda suke da mahimman aikace-aikace a fagen kwayoyin halitta.
3. As a fumigant: Due to its toxicity to insects and microorganisms, DMDS can be used as a fumigant to control pests and fungi in stored grains, warehouses, and greenhouses. Zai iya kashe kwari da yawa da fungi, suna taimakawa kare samfuran aikin gona da hana yaduwar cututtuka.
4. Ana amfani da DMDs a cikin masana'antar Semicontortory na wasu hanyoyin ajiya kamar ajiye kayan maye (CVD). Ana iya amfani da shi don adana sulfur - wanda ya ƙunshi fina-finai na bakin ciki, wanda ke da aikace-aikace a cikin ƙuruciyar na'urorin lantarki kamar masu bincike da masu sihiri da masu sirri.
5. A cikin bayanan sunadarai: Za'a iya amfani da DMDs azaman sake dawowa a cikin masu binciken sunadarai. Zai iya amsawa tare da wasu ƙungiyoyi masu aiki a cikin mahaɗan ƙwayoyin cuta don samar da abubuwan hawa tare da mafi kyawun chromatographic ko na Spectroscopic Propertrapic, sauƙaƙe rabon wadannan mahadi. Misali, ana iya amfani dashi a cikin bincike game da mai kits na mai da sauran ƙwayoyin cuta ta hanyar cututtukan gas - taro na biyu (GC - ms).
