Abstract: A method of storing and/or transporting oxo alcohol, comprises: combining an oxo alcohol having an initial aldehyde content X and an initial peroxide content Y with 5 ppm to 100 ppm of a phenolic antioxidant, preferably a phenolic antioxidant without ester linkage groups; and storing and/or transporting the oxo alcohol. The oxo alcohol can be used to produce a plasticizer, e.g., without adversely affecting color.

Abstract: A method of purifying alcohol produced in a process that includes the Oxo process is disclosed. Aldehyde from the Oxo process that remains with the alcohol is removed by a reaction with an alkali sulphite to produce an insoluble adduct and alcohol having a reduced amount of aldehyde mixed with it. The adduct is removed from the alcohol by filtration.

Abstract: A process for preparing 2,2-bis(4-hydroxyphenyl)propane (p,p-bisphenol-A) from 2,4,4-trimethyl-2-(4-hydroxyphenyl)chroman (chroman 1.5) is disclosed. Phenol and chroman 1.5 are contacted over an acidic ion exchange resin at a given temperature for a given period of time. The process results in improved quality of p,p-bisphenol-A, better performance of catalyst, improved raw material usage, and reduced waste.
