摘要:
Novel bis(3',5'-mono or dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketones are prepared by reacting a (3',5'-mono or dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketone with an N,N-dihydrocarbyl-2,6-mono or dihydrocarbyl-4-aminomethylphenol and an alkyl halide in the presence of an alkaline earth metal halide. The products are useful as antioxidants.
摘要:
4-(.alpha.-hydrocarbyl-.alpha.-cyanomethyl)2,6-di-hydrocarbyl-substituted phenols having the formula ##STR1## wherein R.sub.1 and R.sub.2 are the same or different monovalent substituents selected from the group consisting of alkyl, aralkyl and cyclic alkyl radicals and R.sub.3 is selected from hydrogen, hydrocarbyl radicals, substituted hydrocarbyl radicals and hydrocarbyloxy radicals are prepared by reacting an N,N-di-hydrocarbyl-4-(.alpha.-hydrocarbyl-.alpha.-aminomethyl)2,6-di-hydrocarbyl-substituted phenol having the formula ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 are as defined above and R.sub.4 and R.sub.5 are the same or different and are selected from hydrogen, hydrocarbyl radicals and substituted hydrocarbyl radicals with an alkali metal cyanide or an alkaline earth metal cyanide in a suitable solvent. The 4-(.alpha.-hydrocarbyl-.alpha.-cyanomethyl)2,6-di-substituted phenol thus formed can readily be converted to the corresponding 4-(.alpha.-hydrocarbyl-.alpha.-cyanomethyl)phenol by dealkylating the substituent groups ortho to the hydroxyl group from the 4-(.alpha.-hydrocarbyl-.alpha.-cyanomethyl)2,6-di-substituted phenol which then can be converted on hydrolysis to the corresponding .alpha.-hydrocarbyl-4-hydroxyphenylacetic acid. These acids have utility as insecticidal and acaricidal intermediates and are deemed to have utility as insecticides themselves as are the 4-(.alpha.-hydrocarbyl-.alpha.-cyanomethyl)2,6-di-substituted phenols of the present invention.

摘要:
A synthetic oil composition comprising the reaction product of an .alpha.-olefin oligomer derived from an .alpha.-olefin monomer containing from about 6 to 20 carbon atoms and from about 0.01 to 1 mole of a phenol per mole of oligomer. The oil composition can be further reacted to form alkoxylated products and can be mixed with polar additives to form homogeneous synthetic lubricants.
