Page/Page column 12-13, (2010/02/13)
A novel manufacturing process is described for producing hindered phenolic alkyl esters, which may be useful as antioxidants. This process simplifies catalyst neutralization and removal during the preparation of hindered phenolic esters. Compositions that comprise the hindered phenolic esters produced according to these methods are also described.
