Phosophoric acids

To reduce pollution, Dow developed a new catalyst system from the mor-denite-zeolite group to replace phosophoric acid or aluminum chloride catalysts. The new catalysts eliminates the disposal of acid wastes and handling corrosive materials. 

Synthesis of a nucleotide from phosophoric acid, sugar, and base can be described as proceeding by two dehydrations, one between phosphoric acid and the sugar and the other between the sugar and the heterocyclic base. Synthesis of the ribonucleotide from phosphoric acid, ribose, and cytosine proceeds as follows ... 

Fresenius first suggested that the acetic acid from acetates could be liberated with phosophoric acid and determined by distillation, with or without the help of...
