Abstract

The oils contain an anti-oxidants one or more diesters of phosphorous or thio-phosphorous acids, or tri-esters of phosphorous acid, derived from monohydric alcohols, >=1 ester gp. coming from an alkyl phenol with one o-posn. to the OH gp. occupied by a hydrocarbon gp. (R) attached through a quaternary C atom and the other o-posn. by (m)ethyl. The phenol ring may contain other hydrocarbon substits. (R) pref. contains not 20C atoms, is aliphatic and is pref. tert-butyl. The other o-posn. is pref. occupied by methyl, and the p-posn. by =4C gp., esp. methyl. The oils are suitable for high temp. use in Ic engines, steam turbines, etc., the ester additives giving improved resistance to oxidn.
