Ojiji
Dimethyl Disulfide (DMDS) bụ kemịkalụ nwere usoro C2H6S2. Ọ bụ mmiri mmiri na-enweghị agba nwere isi siri ike na-adịghị mma. Lee ụfọdụ n'ime ojiji ya bụ isi:
1. N'ụlọ ọrụ mmanụ ala: A na-ejikarị DMDS eme ihe dị ka ihe mgbakwunye nwere sọlfọ n'ime nchacha mmanụ ala. Ọ na-enyere aka imeziwanye arụmọrụ nke usoro desulfurization site n'ịrụ ọrụ dị ka isi iyi sọlfọ. Ọ nwere ike imeghachi omume na oxides metal n'elu ihe ndị na-eme ka desulfurization na-akpali, na-eme ka ọrụ ha na nkwụsi ike ha dịkwuo mma, ma si otú a na-eme ka ọnụego mwepụ nke ihe ndị nwere sọlfọ dị na ngwaahịa mmanụ ala dịkwuo mma.
2. N'ime ụlọ ọrụ kemịkalụ: Ọ bụ ihe dị mkpa maka imepụta ọtụtụ ihe ndị nwere sọlfọ organic. Dịka ọmụmaatụ, enwere ike iji ya kwadebe methanethiol, nke a na-ejikwa eme ihe n'ịmepụta ọgwụ nje, ọgwụ, na kemịkalụ ndị ọzọ dị mma. Enwere ike iji DMDS mee ihe na njikọta nke ụfọdụ sọlfọ - nke nwere heterocyclic compounds, nke nwere ọrụ dị mkpa n'ọhịa nke njikọ organic.
3. Dịka ihe na-egbu nje: N'ihi nsí ya nye ụmụ ahụhụ na ụmụ nje, enwere ike iji DMDS dị ka ihe na-egbu nje iji chịkwaa ụmụ ahụhụ na ero n'ime ọka echekwara, ụlọ nkwakọba ihe, na ụlọ griinhaus. Ọ nwere ike igbu ọtụtụ nje na ero nke ọma, na-enyere aka ichekwa ngwaahịa ugbo echekwara ma gbochie mgbasa nke ọrịa.
4. N'ihe gbasara eletrọniki: A na-eji DMDS eme ihe n'ụlọ ọrụ semiconductor maka usoro ụfọdụ dịka itinye anwụrụ kemịkalụ (CVD). Enwere ike iji ya tinye sọlfọ - nke nwere ihe nkiri dị gịrịgịrị, nke nwere ngwa n'ịmepụta ngwaọrụ eletrọniki dịka transistors na sensọ.
5. Na kemistri nyocha: Enwere ike iji DMDS dị ka ihe na-eme ka ihe dị iche iche pụta ìhè na kemistri nyocha. Ọ nwere ike imeghachi omume na ụfọdụ otu ọrụ dị na ihe ndị dị ndụ iji mepụta ihe ndị nwere ihe ndị dị ndụ ka mma na chromatographic ma ọ bụ spectroscopic, na-eme ka nkewa na nchọpụta nke ihe ndị a dị mfe. Dịka ọmụmaatụ, enwere ike iji ya na nyocha nke abụba asịd na ihe ndị ọzọ dị ndụ site na gas chromatography - mass spectrometry (GC - MS).
