With a total of 5 patents to his name, Phan's work has advanced the understanding and application of chemical processes in various industries.
Latest Patents
One of Hao V Phan's latest patents focuses on the purification of arylene polyphosphate esters. This innovative process minimizes or prevents emulsion formation and suppresses hydrolytic product degradation during the purification of impure bisphenol-A bis(diphenylphosphate). The method involves creating a hydrocarbon solution of bisphenol-A bis(diphenylphosphate) along with impurities in a solvent that includes at least one aromatic hydrocarbon and one paraffinic hydrocarbon. The solution is then washed with water or an aqueous buffer solution, followed by multiple washes with an aqueous alkaline solution. This results in the separation of a purified organic phase from an aqueous phase, allowing for the recovery of the purified product.
Another significant patent by Phan is a process for chiral enrichment of optically active carboxylic acids. This highly efficient method enhances the chiral purity of a partially enriched mixture of enantiomers. By mixing an acid with an aqueous solution of the partially enriched mixture, the process yields a further enriched mixture with a higher percentage of the desired enantiomer. This advancement is crucial for applications in pharmaceuticals and other fields requiring high purity levels of chiral compounds.
