Intangiriro

1.5-Pentodithiol ni urugimbu rwa organosulfur.

 

Ubwiza:

1,5-pentanedithiol ni ibara ritagira ibara ryumuhondo ryerurutse rifite impumuro nziza. Irashobora gushonga mumashanyarazi menshi nka alcool, ethers, hamwe na hydrocarubone.

 

Koresha:

1.5-pentanedithiol ifite imbaraga zo kugabanya no guhuza ibikorwa, kandi ifite imikoreshereze itandukanye mubushakashatsi bwimiti ninganda:

Irashobora gukoreshwa nkibintu bigabanya kandi bigorana muri synthesis organique kugirango byorohereze iterambere ryimiti imwe nimwe.

 

Uburyo:

1.5-pentadithiol irashobora kuboneka mugukora 1-pentene hamwe na thiol mugihe cya alkaline. Muri laboratoire, irashobora kandi guhuzwa hiyongereyeho thio-butyrolactone.

 

Amakuru yumutekano:

1.5-pentanedithiol ni ibintu bitera uburakari bishobora gutera uburakari kandi bigashya bihuye n'amaso n'uruhu. Ibikoresho bikwiye birinda nka gants, goggles, na kote ya laboratoire bigomba kwambarwa mugihe ukoresha no gukora. Witondere kuyikoresha ahantu hafite umwuka uhagije kandi wirinde guhumeka umwuka wacyo. 1.5-pentanedithiol nayo ifite uburozi runaka kandi igomba kwirindwa kumara igihe kinini no kuyifata. Mugihe habaye impanuka, ubuvuzi bwihutirwa bugomba guhita bukorwa kandi hagomba gushakishwa ubuvuzi mugihe gikwiye.
