Ojiji
Deethyl na-enwe nsogbu (DMD) bụ usoro kemịkalụ na usoro C2H6S2. Ọ bụ mmiri na-enweghị agba nke nwere isi siri ike, na-adịghị mma. Lee ụfọdụ n'ime isi ya:
1. Na ụlọ ọrụ mmanụ: A na-eji DMDs rụọ ọrụ dị ka sọlfọ - nwere mgbakwunye na mmanụ na-ere mmanụ. Ọ na - enyere aka imeziwanye arụmọrụ nke usoro desdulfurdization site na ime ihe dị ka sọlfọ. Ọ nwere ike meghachi omume na ọla dị n'elu ebe a na-emepụta ihe, na-eme ka ọrụ ha na nkwụsi ike, wee si otú a na-eme ka iwepụ ya na ngwaahịa mmanụ.
2. N'ime ụlọ ọrụ kemịkalụ: ọ bụ akụrụngwa dị mkpa maka njikọta sọlfọ dị iche iche - nwere ogige. Iji maa atụ, enwere ike iji ya kwadebe methannethiol, nke a na-ejikarị ya na nrụpụta ọgwụ ọgwụ, ọgwụ na kemịkal ndị ọzọ. Enwere ike iji DMDs na njikọta ụfọdụ sọlfọ - nke nwere ngwakọta hetecyclic, nke nwere ngwa dị mkpa na nhazi nke njikọta ngwakọta.
3. Dị ka ihe na-egbu egbu: n'ihi ụtarị na ụmụ ahụhụ ya na ụmụ ahụhụ na microorganisms, a ga-eji DMDs dị ka ihe na-adịghị mma iji chịkwaa pests, ụlọ nkwakọba ihe na ụlọ nkwakọba akwụkwọ. Ọ nwere ike igbu ọtụtụ pests na Fungi, na-enyere aka ichebe ngwaahịa ọrụ ugbo ma gbochie mgbasa nke ọrịa.
4. N'ala elektrọnik: A na-eji DMD na ụlọ ọrụ semiconductor maka ụfọdụ usoro dị ka chekwasịrị ihe mkpuchi mmiri (CVD). Enwere ike iji ya tinye sọlfọ - nke nwere ihe nkiri dị mkpa, nke nwere ngwa na fatịrịtara ngwaọrụ elektrọnik dịka transpors na sensọ.
5. Na nyocha vitalist: enwere ike iji DMD dị ka ihe ndebanye aha na-eme nyocha na nyocha nke nyocha. Ọ nwere ike meghachi omume na ụfọdụ ọrụ na ogige organic organic ma ọ bụ ihe dị mma ma ọ bụ ihe dị mma, na-eme ka nkewa na ịchọpụta ihe ndị a. Dịka ọmụmaatụ, enwere ike iji ya na nyocha nke abụba na akụrụngwa ndị ọzọ site na gas chromatography - Mass Stickrometry (GC - ms).
