Taw qhia

1,5-Pentodithiol yog ib qho organosulfur compound.

 

Zoo:

1,5-pentanedithiol yog xim tsis muaj xim rau lub teeb daj pob tshab kua nrog cov ntxhiab tsw. Nws yog soluble hauv ntau cov kuab tshuaj organic xws li cawv, ethers, thiab hydrocarbon solvents.

 

Siv:

1,5-pentanedithiol muaj zog txo thiab kev sib koom tes, thiab muaj ntau yam kev siv hauv kev sim tshuaj thiab kev lag luam:

Nws tuaj yeem siv los ua tus neeg sawv cev txo qis thiab cov neeg ua haujlwm complexing hauv cov organic synthesis los pab txhawb kev nce qib ntawm qee cov tshuaj tiv thaiv.

 

Txoj kev:

1,5-pentadithiol tuaj yeem tau txais los ntawm kev ua haujlwm 1-pentene nrog thiol nyob rau hauv cov xwm txheej alkaline. Hauv chav kuaj, nws tuaj yeem ua ke nrog qhov sib ntxiv ntawm thio-butyrolactone.

 

Cov ntaub ntawv kev nyab xeeb:

1,5-pentanedithiol yog ib yam khoom uas ua rau khaus khaus thiab kub hnyiab ntawm qhov muag thiab tawv nqaij. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab cov tsho hauv lab yuav tsum hnav thaum siv thiab ua haujlwm. Nco ntsoov siv nws nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob nqus nws vapors. 1,5-pentanedithiol kuj muaj qee yam tshuaj toxicity thiab yuav tsum tau zam kom tsis txhob cuam tshuam ntev thiab noj. Thaum muaj xwm txheej, kev kho mob xwm txheej ceev yuav tsum tau ua tam sim ntawd thiab kev kho mob yuav tsum tau nrhiav kom tau raws sijhawm.
