| titleOfInvention | PROCEDURE FOR THE PREPARATION OF ANTIOXIDANT CONTAINING SULFUR. |
| abstract | Procedure for the preparation of antioxidants containing sulfur, characterized in that two moles of the same or different hydroxyaryl compounds, of formula I ** (See formula) ** it is reacted with 1 mol of an aldehyde of formula II ** (See formula) ** to form a compound of formula III ** (See formula) ** in whose formulas one of the X1 and X2 or X1'and X2' each signify the hydroxyl group and the other hydrogen, R1 and R1'each mean a branched alkyl group on the alpha-carbon atom, which shows in total 3 to 20 carbon atoms, and which may contain an optionally substituted phenyl radical, or a cycloalkyl group showing from 5 to 20 5 to 12 membered ring carbon atoms, R2 and R2'each mean hydrogen, a straight-chain lower alkyl group, an optionally substituted phenyl group or the same as R1. R3 and R3'as well as R4 and R5 each signify hydrogen or a lower alkyl group, R6 means hydrogen an alkyl group showing from 1 to 19 carbon atoms or an oxalkyl or dialkyl group showing from 2 to 19 carbon atoms, R7 means hydrogen or the methyl group R8 means hydrogen or the methyl group and additionally, when R7 is hydrogen, likewise a 2-carbon alkyl group.
