Polyphosphoric-Acid PPA CAS 8017-161 Industrial Catalyst Liquid

High effective component and strong catalytic activity. Our industrial grade polyphosphoric-acid has stable P2O5 content >=84% and equivalent phosphoric-acid up to 115%. It shows much stronger dehydra

Stable batch quality with strict impurity control. Adopting continuous synthesis process, we strictly limit harmful impurities including sulfate, chloride and heavy metals. COA test certificate is pro

Liquid form for convenient feeding. It is transparent viscous liquid at ambient temperature. No heating or dissolution is required. It can be pumped directly, saving the dissolution step of solid acid

Controllable corrosion and compatible with common anti-corrosion equipment. Compared with fuming sulfuric-acid and other strong acid catalysts, it has no oxidizing property and will not carbonize raw

Moderate hygroscopicity and good storage stability. Qualified polyphosphoric-acid hardly crystallizes at room temperature. It hydrolyzes slowly under well-sealed condition and can be stored for a long

Wide application covering various fine chemical fields. It can work as cyclizing agent, acylation agent and dehydrating agent for synthesis of pharmaceuticl intermediates, dyes & pigments, flavors
