Intshayelelo

I-1,5-Pentodithiol yi-organosulfur compound.

 

Umgangatho:

I-1,5-pentanedithiol ngulwelo olungenambala ukuya ekukhanyeni olutyheli olucacileyo kunye nevumba elibi. Iyanyibilika kwizinyibilikisi ezininzi ze-organic ezifana ne-alcohols, ii-ethers, kunye nezinyibilikisi ze-hydrocarbon.

 

Sebenzisa:

I-1,5-pentanedithiol ineepropati ezinamandla zokunciphisa kunye nokulungelelanisa, kwaye ineendlela ezahlukeneyo zokusetyenziswa kwiimvavanyo zemichiza kunye noshishino:

Ingasetyenziselwa njenge-agent yokunciphisa kunye ne-agent eyinkimbinkimbi kwi-organic synthesis ukuququzelela inkqubela phambili yeekhemikhali ezithile.

 

Indlela:

I-1,5-pentadithiol inokufumaneka ngokuphendula i-1-pentene kunye ne-thiol phantsi kweemeko ze-alkaline. Kwibhubhoratri, inokuphinda idityaniswe kunye nokongezwa kwe-thio-butyrolactone.

 

Ulwazi ngoKhuseleko:

I-1,5-pentanedithiol yinto ephazamisayo enokubangela ukucaphuka kunye nokutshisa ngokudibana kwamehlo kunye nolusu. Izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, iiglasi, kunye needyasi zaselebhu kufuneka zinxitywe xa usebenzisa kwaye usebenza. Qinisekisa ukuba uyisebenzisa kwindawo engenamoya kwaye uphephe ukuphefumla umphunga wayo. I-1,5-pentanedithiol nayo inetyhefu ethile kwaye kufuneka igwenywe ngenxa yokuvezwa kwexesha elide kunye nokungena. Xa kwenzeka ingozi, unyango olungxamisekileyo kufuneka luqhutywe ngokukhawuleza kwaye unyango kufuneka lufunwe ngexesha elifanelekileyo.
