Title: Hsiang P Liao: Innovator in Phosphoric Acid Ester Compositions
Introduction
Hsiang P Liao is a notable inventor based in Princeton, NJ, who has made significant contributions to the field of chemical engineering. He holds a total of five patents, showcasing his expertise and innovative spirit in the development of phosphoric acid ester compositions.
Latest Patents
Liao's latest patents include a process for the manufacture of alkyl diaryl phosphate esters. This process involves heating a monohydric alcohol or alkoxy alcohol with a triaryl phosphate, such as triphenyl phosphate, in the presence of a catalytic amount of an alkali metal phenoxide. The resulting mixed phosphoric acid ester composition contains less than 4 weight percent of a triaryl phosphate, from about 10 to about 20 weight percent of an aryl dialkyl phosphate, and from about 65 to about 80 weight percent of an alkyl diaryl phosphate. The composition may be separated from by-products of the reaction by distillation. Another patent focuses on the manufacture of mixed phosphoric acid ester compositions, which are prepared by heating a monohydric alcohol with aqueous sodium hydroxide to form the sodium alkoxide. This process also involves distilling off the water as an alcohol azeotrope and reacting the alcohol sodium alkoxide with triphenyl phenol.
