    摘要： The present disclosure provides A lubricant composition comprises an antioxidant; and an esterified polyalkylene glycol: R1[O(R2O)n(R3O)m(C═O)R4]p, wherein R1 is a linear alkyl having 1 to 18 carbon atoms, a branched alkyl having 4 to 18 carbon atoms or an aryl with 6 to 30 carbon atoms; R2O is an oxypropylene moiety derived from 1,2-propylene oxide; R3O is an oxybutylene moiety derived from butylene oxide, wherein R2O and R3O are in a block or a random distribution; R4 is a linear alkyl with 1 to 18 carbon atoms, a branched alkyl with 4 to 18 carbon atoms or an aryl with 6 to 18 carbon atoms; n and m are each independently integers ranging from 0 to 20 wherein n+m is greater than 0, and p is an integer from 1 to 4, wherein the antioxidant is present in an amount by weight of at least 0.5% to 20% based upon the weight of the antioxidant and the esterified polyalkylene glycol and the antioxidant is soluble in the esterified polyalkylene glycol in an amount of at least 0.5% by weight. The lubricant composition may be used as an additive to form a hydrocarbon lubricant composition.
