PRODUCTION OF WET PROCESS PHOSPHORIC ACID

摘要

The yield of phosphoric acid in the "wet process" synthesis of said acid is improved by adding to the phosphate rock-sulfuric acid reaction medium a small but effective amount of a "processing aid," which also serves as a defoaming agent, comprised of a mixture of (1) an amide of a lower alkanol amine and fatty acid and (2) fatty acid, in specifically defined proportions as determined by the specific components of the composition.
