Nhanganyaya

1,5-Pentodithiol inhengo ye organosulfur.

 

Hunhu:

1,5-pentanedithiol imvura isina ruvara kune yero inoonekera uye inonhuhwirira. Inonyungudika mune zvakawanda organic zvinonyungudutsa zvakaita sedoro, ether, uye hydrocarbon solvents.

 

Shandisa:

1,5-pentanedithiol ine simba rekudzikisa uye kuronga zvivakwa, uye ine zvakasiyana-siyana zvekushandisa mukuyedza makemikari uye indasitiri:

Inogona kushandiswa seanodzikisira mumiririri uye anoomesera mumiriri mune organic synthesis kufambisa kufambira mberi kwemamwe maitiro emakemikari.

 

Nzira:

1,5-pentadithiol inogona kuwanikwa nekuita 1-pentene ne thiol pasi pemamiriro e-alkaline. Murabhoritari, inogona zvakare kugadzirwa nekuwedzera kwethio-butyrolactone.

 

Zvekuchengetedza

1,5-pentanedithiol chinhu chinogumbura chinogona kukonzera kutsamwa uye kupisa mukubatana nemaziso uye ganda. Midziyo yekudzivirira yakakodzera senge magirovhosi, magirovhosi, uye majasi erabhoritari anofanirwa kupfekwa paunenge uchishandisa nekushanda. Iva nechokwadi chekuishandisa munzvimbo ine mhepo inofefetera zvakanaka uye dzivisa kufemesa hutsi hwayo. 1,5-pentanedithiol inewo humwe huturu uye inofanira kudzivirirwa nokuda kwekuratidzwa kwenguva refu uye kunwa. Muchiitiko chetsaona, kurapwa kwekukurumidzira kunofanira kuitwa pakarepo uye kurapwa kunofanira kutsvakwa panguva yakakodzera.
