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.

A molybdate ester represented by the following formula:
where R1 is a hydrocarbon chain, R2 is either a hydrogen atom or a hydrocarbon chain, and m and n are independently from 1 to 5, is effective when used in a lubricating composition in an amount sufficient to provide about 50-5000 ppm of molybdenum, with respect to friction and wear reduction, while providing improved protection against copper and lead corrosion.
A heat-resistant composition useful as a flame retardant, a flame retardant composition containing the same, and a flame-retardant resin composition are provided. The composition contains 20 to 50 parts by mass of a specific melamine salt as component (A), 50 to 80 parts by mass of a specific piperazine salt as component (B), and 1 to 50 parts by mass of a phosphoric ester compound having a specific structure as component (C), wherein the sum of the components (A) and (B) is 100 parts by mass.
