I-Propylphosphonic anhydride (CAS# 68957-94-8)
| Amakhodi Engozi | R20 – Kuyingozi ngokuhogela umoya R34 – Ibangela ukusha U-R61 - Ingabangela ukulimala enganeni engakazalwa |
| Incazelo Yokuphepha | S23 – Ungawuphefumuli umhwamuko. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) |
Isingeniso
Izakhiwo:
I-Propylphosphonic anhydride iyinhlanganisela engenambala ukuya kokuphuzi ngokukhanyayo yesigaba se-propane esekelwe ku-phosphonic anhydride. Kuyinhlanganisela encibilikayo emanzini engancibilika emanzini ukwenza isixazululo. Iwuketshezi ekamelweni lokushisa futhi inephunga elimnandi.
Isebenzisa:
I-Propylphosphonic anhydride ivame ukusetshenziswa njenge-corrosion inhibitor, i-flame retardant, kanye nesengezo kuketshezi lwensimbi ekukhiqizweni kwezimboni. Ibuye isetshenziswe emkhakheni we-biomedicine.
I-synthesis:
I-Propylphosphonic anhydride ingahlanganiswa ngokusabela kwe-phosphorus oxychloride nge-propylene glycol.
Ukuphepha:
I-Propylphosphonic anhydride inokuphepha okuphezulu uma kuqhathaniswa, kodwa kufanele kuthathwe izinyathelo zokuphepha. Ukuthinta isikhumba noma ukuhogela okugxilile kwe-propylphosphonic anhydride kungadala ukucasuka nokungakhululeki, ngakho-ke ukuchayeka isikhathi eside kufanele kugwenywe. Izinto zokuzivikela ezifanele kufanele zigqokwe ngesikhathi sokusetshenziswa, nendawo ezungezile kufanele kungene umoya kahle. Izingozi empilweni yomuntu kanye nemvelo zingancishiswa ngokusebenzisa indlela efanele kanye nezindlela zokugcina.
