Isingeniso
I-Dimethiomethane (eyaziwa nangokuthi i-methyl sulfide) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dimethylthiomethane:
Ikhwalithi:
- Ukubukeka: Uketshezi olungenambala
- Iphunga: Inephunga elinamandla le-hydrogen sulfide
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol ne-ether
Sebenzisa:
- Njenge-solvent: I-Dimethiomethane iyi-solvent ebalulekile ye-organic engasetshenziswa ukuncibilikisa nokuhlanza ama-organic compounds.
- Chemical synthesis: Ivamise ukusetshenziswa njenge-reagent futhi imaphakathi ku-organic synthesis, futhi ibamba iqhaza kwezinye i-alkylation, i-oxidation, i-sulfidation nokunye ukusabela.
- Izinto ze-Polymer: I-Dimethylthiomethane nayo ingasetshenziselwa ukuxhumanisa nokuguqulwa kwama-polymers.
Indlela:
- I-Dimethylthiomethane ingatholakala ngokusabela i-methyl mercaptan nge-dimethyl mercaptan. Ekuphenduleni, iodide ye-sodium noma i-sodium bromide ivame ukusetshenziswa njenge-catalyst.
Ulwazi Lokuphepha:
- I-Dimethylthiomethane inephunga elimnandi futhi iyacasula emehlweni, isikhumba kanye nomgudu wokuphefumula. Amagilavu okuzivikela, izibuko zokuphepha kanye nokuvikela ukuphefumula kufanele kugqokwe lapho kusetshenziswa.
- Ngesikhathi sokugcina nokuphatha, ukuthintana nama-oxidizing aqinile nama-acids kufanele kugwenywe ukuvimbela ukusabela kwamakhemikhali okuyingozi.
- Uma ishisiwe, i-dimethylthiomethane ikhiqiza amagesi anobuthi (isb. i-sulphur dioxide) futhi kufanele isetshenziswe endaweni enomoya omuhle.
- Lapho uphatha futhi ulahla imfucuza, sicela ulandele imithetho nemithetho yendawo efanele.
