Polyphosphoric acid is a protonic acid, which can dissolve a variety of low molecular and high molecular organic compounds. Used as a catalyst or solvent for condensation, cyclization, rearrangement, substitution and other reactions. Used as a compound cyclizing agent and acylating agent in organic synthesis. Also used as a substitute for

RELEASED MAY 24 An acid that forms positive hydrogen ions (or, strictly, oxonium ions) in aqueous solution. The term is used to distinguish ‘traditional’ acids from Lewis acids or from Lowry-Brønsted acids in nonaqueous solvents. Protonix (pantoprazole) is a proton pump inhibitor that decreases the amount of acid produced in the stomach. Protonix is used to treat erosive esophagitis (damage to the esophagus from stomach acid caused by gastroesophageal reflux disease, or GERD) in adults and children who are at least 5 years old. Pantoprazole is usually given for up to 8 Pantoprazole is a medicine used to treat damage to the esophagus caused by gastroesophageal reflux disease (GERD) — a condition where acid from the stomach flows backwards. I don’t know! But I have an educated guess.

Three- and four-armed star-shaped poly(ε-caprolactone)s were synthesized from trimethylolpropane and pentaerythritol as initiators using fumaric acid as an activator of the monomer, respectively. Star-shaped poly(ε-caprolactone)s could be satisfactorily obtained, which was confirmed by size exclusion chromatography equipped with low-angle laser light scattering and viscometer detectors The global propionic acid market in terms of revenue was estimated to be worth $935.7 million in 2012 and is expected to reach $1,608.8 million by 2018, growing at a CAGR of 7.8% from 2013 to 2018. Europe dominated the global market in 2012. Consequently, three types of protonic acid sites with distinct superacid strengths, which correspond to (31)P chemical shifts of 92.1, 89.4, and 87.7 ppm, were observed for HPW samples loaded with less than three molecules of TMPO per Keggin unit.

A protonic acid forms positive hydrogen ions (protons) in aqueous solution. Learn more information about protonic acid. In this article we'll discuss protonic acid. Non-aqueous Protonic Acid-Base Systems We ordinarily think of Brønsted-Lowry acid-base reactions as taking place in aqueous solutions, but this need not always be the case. A more general view encompasses a variety of acid-base solvent systems , of which the water system is only one (Table \(\PageIndex{1}\)).
