i-diphenylphosphineoxide CAS:4559-70-0

I-Diphenylphosphineoxide isebenza njengesixhumi esibalulekile ekukhiqizweni kwezinto ezivimbela umlilo zama-polymer, izindwangu, nezinto zokwakha. Ukufakwa kwayo ekwakhiweni kwezinto ezivimbela umlilo kusekela ukuthuthukiswa kwezinto ezinokumelana nomlilo okuthuthukisiwe, ukucindezela intuthu, kanye nokuqina kokushisa, ngaleyo ndlela kuqinisekisa ukuphepha kanye nokuhambisana nemithethonqubo yokuvimbela umlilo ezisetshenziswayo ezahlukahlukene. Amandla enhlanganisela yokuphazamisa inqubo yokusha ayenza ibe yingxenye ebalulekile kubuchwepheshe obuvimbela umlilo kuzo zonke izimboni. Emkhakheni wokwenziwa kwezinto eziphilayo, i-Diphenylphosphineoxide ithola ukusetshenziswa njenge-reagent eguquguqukayo yokuguqulwa kwama-molecule ezinto eziphilayo kanye nokudalwa kwezakhiwo zamakhemikhali eziyinkimbinkimbi. Ukusebenza kwayo kusiza ukwethulwa kwamaqembu asebenzayo aqukethe i-phosphorus, okuvumela ukuhlanganiswa kwamakhemikhali akhethekile, izinto ezivimbela imithi, kanye nezinto zezolimo. Indima yenhlanganisela ekuguqulweni kwezinto eziphilayo kanye ne-catalysis inegalelo ekuthuthukisweni kokwenziwa kwamakhemikhali kanye nokuthuthukiswa kwezinto ezintsha ezinezakhiwo ezilungiselelwe. Ngaphezu kwalokho, inhlanganisela idlala indima ebalulekile njengesiqinisi kanye ne-antioxidant embonini ye-polymer. Amandla ayo okususa ama-free radicals nokuvimbela ukusabela kwe-oxidation kunegalelo ekulondolozweni kwezakhiwo zezinto ezibonakalayo, kwandise impilo yesevisi kanye nokusebenza kwezinto ze-polymeric ezisetshenziswa ezimotweni, ekwakheni, nasezimpahleni zabathengi. Ngaphezu kwalokho, i-Diphenylphosphineoxide isebenza njengosizo lokucubungula kanye nokuhambisana nezinhlanganisela ze-polymer, ithuthukisa ukuhambisana kanye nezakhiwo zemishini zezinhlelo ze-polymer ezixubile, inegalelo ekuthuthukisweni kwezinto ezintsha ezinezimpawu zokusebenza ezithuthukisiwe. Ngaphezu kwalokho, le nhlanganisela isetshenziswa ekwakhiweni kwezithasiselo ezikhethekile zezinto zokugcoba, uketshezi lokusebenza kwensimbi, kanye nezimbozo zezimboni. Izakhiwo zayo zamakhemikhali zivumela ukudalwa kwezithasiselo zokusebenza okuphezulu ezithuthukisa ukugcotshwa, ukuvikelwa kokugqwala, kanye nokuqina kokushisa ezisetshenziswayo ezimbonini ezahlukahlukene. Ngokuthuthukisa ukusebenza kwalezi ziketshezi nezimbozo, i-Diphenylphosphineoxide inegalelo ekusebenzeni kahle nasekuphileni isikhathi eside kwemishini, izingxenye, kanye nezindawo emikhakheni eyahlukene yezimboni. Ngamafuphi, i-Diphenylphosphineoxide ikhombisa ukusetshenziswa kwayo okubanzi njengenhlanganisela eguquguqukayo enezinhlelo zokusebenza ezahlukahlukene ezimbonini, kufaka phakathi izinto ezivimbela ilangabi, ukwakheka kwezinto eziphilayo, izithasiselo ze-polymer, kanye namakhemikhali akhethekile. Isakhiwo sayo esiyingqayizivele sama-molecule kanye nokusabela kwayo kunegalelo ekusungulweni okuqhubekayo kanye nentuthuko kwisayensi yezinto ezibonakalayo, ubunjiniyela bamakhemikhali, kanye nezinqubo zezimboni.
