Imikoreshereze
Dimethyl Disulfide (DMDS) ni ikinyabutabire gifite formula ya C2H6S2. Ni amazi adafite ibara kandi afite impumuro mbi. Dore zimwe mu ngaruka zayo z'ingenzi:
1. Mu nganda za peteroli: DMDS ikoreshwa cyane nk'inyongera irimo sulfur mu gutunganya peteroli. Ifasha kunoza imikorere y'ibikorwa byo gukuramo sulfur mu gukora nk'isoko ya sulfur. Ishobora gukorana na oxyde z'icyuma ku buso bwa catalysts zo gukuramo sulfur, yongera imikorere yazo n'ubudahangarwa bwazo, bityo ikanoza umuvuduko wo gukuramo ibintu birimo sulfur mu bikomoka kuri peteroli.
2. Mu nganda z’imiti: Ni ingenzi mu gukora imvange zitandukanye zirimo sulfur. Urugero, ishobora gukoreshwa mu gutegura methanethiol, ikoreshwa cyane mu gukora imiti yica udukoko, imiti, n’ibindi binyabutabire byiza. DMDS ishobora kandi gukoreshwa mu gukora imvange zimwe na zimwe zirimo sulfur, zifite akamaro kanini mu gukora imvange y’imiti.
3. Nk'umuti urwanya udukoko: Bitewe n'uburozi bwayo ku dukoko n'udukoko duto, DMDS ishobora gukoreshwa nk'umuti urwanya udukoko n'udukoko mu binyampeke bibitswe, mu bubiko no mu mazu acururizwamo ibiribwa. Ishobora kwica udukoko n'udukoko dutandukanye, igafasha mu kurinda umusaruro w'ubuhinzi wabitswe no gukumira ikwirakwira ry'indwara.
4. Mu rwego rw'ibikoresho by'ikoranabuhanga: DMDS ikoreshwa mu nganda za semiconductor mu bikorwa bimwe na bimwe nko gushyira umwuka mu kirere (CVD). Ishobora gukoreshwa mu gushyiramo filime ntoya zirimo sulfur, zifite akamaro mu gukora ibikoresho by'ikoranabuhanga nka transistors na sensors.
5. Mu buhanga bwo gusesengura: DMDS ishobora gukoreshwa nk'ikintu gihindura imiterere y'umubiri muri buhanga bwo gusesengura. Ishobora gukorana n'amatsinda amwe n'amwe y'imikorere mu binyabutabire by'umwimerere kugira ngo ikore ibinyabutabire bifite imiterere myiza ya chromatografiya cyangwa spectroskopiya, byorohereza gutandukanya no kubona ibinyabutabire. Urugero, ishobora gukoreshwa mu gusesengura aside irike n'ibindi binyabutabire by'umwimerere hakoreshejwe gaze chromatography - mass spectrometry (GC - MS).
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
