text: A method for the production of a dry, granular solid acid composition composed essentially of pyrophosphoric acid which comprises mixing liquid phosphoric acid containing 78 to 81% P 0 with a granular mass of previously prepared solid pyrophosphoric acid in the proportion of 1-7 parts of solid pyrophosphoric acid per part of liquid phosphoric acid, maintaining the temperature during mixing below 50 C. and continuing mixing until the resultant mixture is a substantially dry, granular solid, and returning a portion of the dry, granular solid for admixture with additional liquid phosphoric acid to produce additional dry, granular solid.
