Isingeniso

I-1,5-Pentodithiol iyinhlanganisela ye-organosulfur.

 

Ikhwalithi:

I-1,5-pentanedithiol iwuketshezi olukhanyayo olungenambala kuya kokuphuzi olukhanyayo olunephunga elimnandi. Incibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, ama-ether, nezinyibilikisi ze-hydrocarbon.

 

Sebenzisa:

I-1,5-pentanedithiol inezakhiwo eziqinile zokunciphisa nokuxhumanisa, futhi inokusetshenziswa okuhlukahlukene ekuhloleni kwamakhemikhali nasembonini:

Ingasetshenziswa njenge-ejenti yokunciphisa kanye ne-ejenti eyinkimbinkimbi ku-organic synthesis ukuze kube lula ukuqhubeka kokusabela okuthile kwamakhemikhali.

 

Indlela:

I-1,5-pentadithiol ingatholakala ngokuphendula i-1-pentene nge-thiol ngaphansi kwezimo ze-alkali. Elabhorethri, ingabuye ihlanganiswe ngokufakwa kwe-thio-butyrolactone.

 

Ulwazi Lokuphepha:

I-1,5-pentanedithiol iyinto ecasulayo engabangela ukucasuka nokushiswa ngokuthintana namehlo nesikhumba. Izimpahla zokuzivikela ezifanele njengamagilavu, izibuko, namajazi elebhu kufanele zigqokwe lapho kusetshenziswa futhi kusebenza. Qiniseka ukuthi uyisebenzisa endaweni enomoya omuhle futhi ugweme ukuhogela umhwamuko wayo. I-1,5-pentanedithiol nayo inobuthi obuthile futhi kufanele igwenywe ukuchayeka isikhathi eside nokungeniswa. Uma kwenzeka ingozi, ukwelashwa okuphuthumayo kufanele kwenziwe ngokushesha futhi ukunakekelwa kwezokwelapha kufanele kufunwe ngesikhathi.
