Latest Patents

Toshimitsu's latest patents include innovative methods for preparing pure phosphoric acid. One of his patents describes a process where phosphate rock is treated with sulfuric acid or hydrochloric acid to create crude phosphoric acid. This crude acid is then solvent extracted with an organic solvent to yield an extracted aqueous phosphoric acid solution. The improvement in this process involves adding a fluorine compound to the extracted solution and concentrating the mixture under reduced pressure, followed by contact with steam or hot air. Another patent focuses on purifying phosphoric acid from crude wet process phosphoric acid containing pentavalent vanadium compounds. This method involves extracting the crude acid with an alcohol of limited water solubility and washing the extracted solution with aqueous phosphoric acid in the presence of a reducing agent for the vanadium compounds.
