This invention describes novel antioxidant compounds which are esters of .omega.,.omega.-bis(dialkylhydroxyphenyl) alkanols having the formula: ##STR1## wherein R.sub.1 is a tertiary alkyl group having 4-8 carbon atoms; R.sub.2 is alkyl having 1-4 carbon atoms; R.sub.3 is a straight chain or branched alkylene group having 1-4 carbon atoms; x is 1-4, n is 1 or 2, and, Y is a group of the formulas ##STR2## when n is 1, where R.sub.4 is alkyl having from 12 to 24 carbon atoms, phenyl, or phenyl substituted with hydroxy of alkyl having 1 to 4 carbon atoms, or combinations thereof, or ##STR3## when n is 2, where R.sub.5 is a direct bond, a straight chain or branched alkylene having 1 to 8 carbon atoms, or a phenylene group, and m is 0 to 4.
这项发明描述了新型抗氧化剂化合物,其为ω,ω-双(二烷基羟基苯基)脂肪醇的酯类,其化学式为:##STR1## 其中R1是具有4-8个碳原子的三级烷基基团;R2是具有1-4个碳原子的烷基;R3是具有1-4个碳原子的直链或支链烷基基团;x为1-4,n为1或2,Y为以下式子之一:##STR2## 当n为1时,其中R4是具有12到24个碳原子的烷基、苯基或取代有1到4个碳原子的烷基羟基苯基,或其组合;或者##STR3## 当n为2时,其中R5是直接键,具有1到8个碳原子的直链或支链烷基,或苯基团,m为0到4。
