Physical thiab Chemical Properties Cov kua dej tsis muaj xim. Boiling point 169-171 ℃, 61 ℃ (1.33kPa). Txoj Kev Npaj: Cov tshuaj sodium methyl mercaptan-anhydrous ethanol yog rhuab rau boiling, cua sov yog nres, thiab chloroethanol ntxiv dropwise nyob rau hauv stirring nyob rau hauv 2H. Cov tshuaj tiv thaiv sib tov yog concentrated, tso cai rau sawv ntsug kom txias, thiab sodium chloride tau lim tawm. Cov filtrate yog fractionated nyob rau hauv lub siab txo kom sau ib tug 68-70 ° C. (2.67kPa) feem kom tau 2-methylthioethanol nyob rau hauv ib tug yield ntawm 74% -82%. Lub hom phiaj: intermediates hauv organic synthesis.

Taw qhia

2-Methylthioethanol, tseem hu ua 2-methylthioethanol, yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos mob: 2-Methylthioethanol yog xim tsis muaj xim rau lub teeb daj.

- Cov ntxhiab tsw: muaj ntxhiab tsw ntawm hydrogen sulfide.

- Solubility: Soluble hauv dej thiab qee cov organic solvents xws li cawv thiab ethers.

- Khoom: Nws yog rhiab heev rau huab cua thiab tuaj yeem oxidized rau disulfide, uas yooj yim rau combustion.

 

Siv:

- Chemical synthesis: 2-methylthioethanol tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis.

- Detergent: Nws tuaj yeem siv ua surfactant thiab detergent hauv kev npaj cov tshuaj detergents.

- Cawv nplaim taws retardant: 2-methylthioethanol tuaj yeem siv los ua cov nplaim hluav taws kub hnyiab.

 

Txoj kev:

2-Methylthioethanol tuaj yeem npaj los ntawm:

- Thioethanol yog tsim los ntawm cov tshuaj tiv thaiv nrog methyl chloride.

- Ethiohydrazine yog tsim los ntawm cov tshuaj tiv thaiv nrog ethanol.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Methylthioethanol muaj cov ntxhiab tsw ntxhiab thiab tuaj yeem ua rau qhov muag thiab tawv nqaij khaus thaum kov.

- Thaum nqus tau, nws tuaj yeem ua rau ua pa ua pa thiab mob hauv siab.

- nqos los yog noj ntau ntau yuav ua rau muaj tshuaj lom, ua rau mob plab hnyuv.

- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav kev nyab xeeb thaum siv.

- Thaum ua haujlwm, khaws cia kom deb ntawm qhov qhib nplaim taws thiab qhov chaw kub kub kom tsis txhob muaj kev sib tsoo.
