I-asidi ye-polyphosphoric CAS 8017-16-1
8017-16-1 I-Polyphosphate (PPA), i-asidi ye-phosphoric exineneyo enoxinzelelo oluphezulu, i-asidi enamandla edityaniswe nokuphelelwa ngamanzi emzimbeni kunye ne-catalysis. Isetyenziswa kakhulu kwi-catalysis ye-fine synthesis, izinto ezisetyenziswa njenge-phosphorus-based flame retardant. Iyabola kakhulu, ikhupha ubushushu xa idibana namanzi. Imisebenzi ifuna amanyathelo angqongqo okulwa nokubola kunye nokuchasana nokutshiza.
Iimpawu eziphambili
I-catalyst enamandla kakhulu ye-protonic acid, i-arhente yokuphelisa amanzi emzimbeni, i-arhente ye-acylation
Ipropati yokulungelelanisa eqinileyo, ukumelana nobushushu obuphezulu, ukungaguquguquki
Ukunyibilika kancinci emanzini abandayo, kuya kukhupha ubushushu obuninzi xa kuxutywa namanzi amaninzi.

Iikhatalyst zokwenziwa kwezinto eziphilayo
Amayeza, iidayi, iziqholo, iikhemikhali ezintle: I-Friedel-Crafts reaction, i-cyclization, i-condensation, i-sulfonation, i-nitration reactions, ngaphandle kokusebenzisa i-sulfuric acid egxininisiweyo, kunye neempendulo ezimbalwa ezingalindelekanga.
Izinto ezithintela ilangatye / Izinto zekhemikhali ezikrwada
Ukuveliswa kwe-ammonium polyphosphate APP, izinto ezithintela ilangatye le-phosphate, izinto ezithintela ilangatye ezisekelwe kwi-phosphorus.
Izithambiso / izongezo zemizi-mveliso
Ukuthintela ukugqwala kwesinyithi, i-arhente yokucoca amanzi, ukurhawuzelela isikhumba, isongezo se-electrolyte yebhetri.
Iioyile / Uhlengahlengiso
Izithambisi, ukuguqulwa kweoyile, ukuqina, i-antioxidant, izongezo zoxinzelelo olugqithisileyo.
• Ukupakisha okuqhelekileyo: 25 kg/idrum
• I-MOQ: kufuneka iqinisekiswe ngokwebanga nendawo ekuyiwa kuyo
