Isingeniso
I-4-Mercapto-4-methylpentan-2-one, eyaziwa nangokuthi i-mercaptopentanone, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Izakhiwo: I-Mercaptopentanone iwuketshezi olungenambala ukuya kokuphuzi okukhanyayo, oluguquguqukayo, futhi lunephunga elikhethekile. Incibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, ama-ether, nama-ester ekamelweni lokushisa.
Ukusetshenziswa: I-Mercaptopentaone inohlu olubanzi lwezinhlelo zokusebenza emkhakheni wamakhemikhali. Ingasetshenziswa njengensiza yokucubungula irabha, esiza ukuthuthukisa ukumelana nokushisa nokumelana nokuguga kwezinto zenjoloba.
Indlela: Ukulungiswa kwe-mercaptopentanone kuvame ukutholwa ngokusabela kokuhlanganiswa. Indlela evamile yokulungiselela iwukusabela i-hex-1,5-dione nge-thiol ukukhiqiza i-mercaptopentanone.
Ulwazi lokuphepha: I-Mercaptopentanone iwuketshezi oluvutha umlilo, gcina kude namalangabi avulekile namazinga okushisa aphezulu. Kufanele kuqashelwe ukugwema ukuthintana nesikhumba, amehlo kanye nokuhogela umhwamuko waso ngesikhathi sokuphatha. I-Mercaptopentanone kufanele isetshenziswe futhi igcinwe endaweni enomoya omuhle futhi kude nomlilo nama-oxidants.
