Taw qhia
Dimethiomethane (tseem hu ua methyl sulfide) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm dimethylthiomethane:
Zoo:
- Cov tsos: cov kua tsis muaj xim
- Cov ntxhiab tsw: muaj ntxhiab tsw ntawm hydrogen sulfide
- Solubility: Soluble nyob rau hauv ntau cov organic solvents xws li ethanol thiab ether
Siv:
- Raws li cov kuab tshuaj: Dimethiomethane yog ib qho tseem ceeb cov kuab tshuaj organic uas yuav siv tau los yaj thiab purify organic tebchaw.
- Chemical synthesis: Nws feem ntau yog siv los ua ib qho reagent thiab nruab nrab hauv cov organic synthesis, thiab koom nrog qee qhov alkylation, oxidation, sulfidation thiab lwm yam kev cuam tshuam.
- Cov ntaub ntawv Polymer: Dimethylthiomethane kuj tuaj yeem siv rau kev sib txuas thiab kev hloov pauv ntawm cov polymers.
Txoj kev:
- Dimethylthiomethane tuaj yeem tau txais los ntawm reacting methyl mercaptan nrog dimethyl mercaptan. Nyob rau hauv cov tshuaj tiv thaiv, sodium iodide los yog sodium bromide feem ntau yog siv los ua catalyst.
Cov ntaub ntawv kev nyab xeeb:
- Dimethylthiomethane muaj cov ntxhiab tsw thiab ua rau lub qhov muag, tawv nqaij thiab ua pa. Cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb thiab tiv thaiv ua pa yuav tsum hnav thaum siv.
- Thaum lub sijhawm khaws cia thiab tuav, kev sib cuag nrog cov neeg ua haujlwm oxidizing muaj zog thiab cov kua qaub yuav tsum zam kom tsis txhob muaj tshuaj lom neeg txaus ntshai.
- Thaum kub hnyiab, dimethylthiomethane tsim cov pa roj carbon monoxide (xws li sulfur dioxide) thiab yuav tsum tau siv rau hauv qhov chaw muaj cua zoo.
- Thaum tuav thiab pov tseg cov khoom pov tseg, thov ua raws li cov cai hauv zos thiab cov cai.
