Polyphosphoric acid CAS 8017-16-1
8017-16-1 Polyphosphate (PPA), cov kua qaub phosphoric uas muaj zog heev, yog cov kua qaub muaj zog ua ke nrog kev qhuav dej thiab catalysis. Siv dav hauv cov catalysis zoo, cov khoom siv raw uas ua los ntawm phosphorus uas tiv taus hluav taws. Muaj zog heev, tso cua sov thaum kov dej. Kev ua haujlwm yuav tsum tau ua kom nruj heev tiv thaiv xeb thiab tiv thaiv dej txaws.
Cov yam ntxwv tseem ceeb
Super muaj zog protonic acid catalyst, dehydrating agent, acylation agent
Muaj zog sib koom tes zoo, tiv taus kub siab, tsis hloov pauv
Maj mam yaj hauv dej txias, yuav tso tawm ntau qhov kub thaum dilution nrog ntau dej
