Taw qhia

3-mercapto-2-butanone, tseem hu ua 2-butanone-3-mercaptoketone los yog MTK, 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: tsis muaj xim tsis muaj kua lossis dawb siv lead ua

- Solubility: Soluble hauv ethanol, ether thiab chloroform, me ntsis soluble hauv dej

 

Siv:

- Tshuaj reagents: feem ntau siv los ua sulfhydrylation reagents nyob rau hauv cov organic synthesis rau synthesis ntawm sulfhydryl tebchaw.

- Kev siv lag luam: 3-mercapto-2-butanone, raws li sulfhydryl reagent, feem ntau yog siv rau hauv kev npaj cov roj hmab additives, roj hmab accelerators, glyphosate (ib tug tshuaj tua kab mob), surfactants, thiab lwm yam.

 

Txoj kev:

Ib txoj hauv kev zoo rau kev npaj ntawm 3-mercapto-2-butanone yog cov tshuaj tiv thaiv ntawm hexane nrog hydrogen sulfide. Cov kauj ruam tshwj xeeb yog ua rau hexanone nrog hydrogen sulfide los ntawm silica gel kem kom tau 3-mercapto-2-butanone.

 

Cov ntaub ntawv kev nyab xeeb:

- 3-mercapto-2-butanone yog cov kua nplaum nplaum thiab yuav tsum tau zam los ntawm cov nplaim taws qhib lossis kub kub.

- Hnav cov kev tiv thaiv tsim nyog xws li tsom iav tiv thaiv, hnab looj tes thiab cov khaub ncaws tawg uas tsim nyog thaum siv.

- Nkag siab thiab ua raws li cov txheej txheem kev khiav hauj lwm thiab cov txheej txheem kev nyab xeeb ua ntej siv.

- Tsis txhob sib cuag nrog cov tshuaj xws li oxidants, muaj zog acids, muaj zog hauv paus, thiab muaj zog oxidants los tiv thaiv kev txaus ntshai.

- Thaum muaj kev sib cuag tsis raug, yaug tam sim nrog dej ntau thiab nrhiav kev kho mob sai.

 

Nws yog ib qho tseem ceeb uas yuav tsum tau siv thiab tswj qhov sib xyaw no kom nyab xeeb thiab ua raws li cov txheej txheem thiab cov lus qhia.
