Abstract
AbstractTo study the relationship between structure and properties of members of the lipidic thiobis phenol series, as extreme pressure additives in lubricants, a series of homologous compounds has been synthesised by the reaction of alkylphenols with sulphur dichloride. The isomeric n‐nonylphenols have been reacted to form the C9 isomeric 2,2′‐and 4,4′‐thiobisphenols. Longer alkyl side‐chains resulted mainly in the formation of 4,4′‐thiobisphenols and some of the 2,2′ isomer. With short alkyl, particularly t‐alkyl side‐chains, steric hindrance resulted in the 2,2′‐compound. Additive studies have indicated that the longer chain 4,4′ compounds possessed antioxidant properties comparable and superior to former commercial branched chain 2,2′ compounds produced from petrochemical intermediates.
