Use of benzyl-phenols as antioxidants

Abstract

Abstract Translated from German Neue Benzylphenole der allgemeinen Formel <IMAGE> in der die Substituenten X und R¹ bis R<7> folgende Bedeutung haben: R¹ ise eine Einfachbindung oder ein zweiwertiger Rest wie z. B. <IMAGE> R² = H, C1-C12-Alkyl, C5-C6-Cycloalkyl, Benzyl, α-Methylbenzyl, α,α-Dimethylbenzyl R³ = H, CH3, Phenyl R<4> = H, CH3, wobei R³ = R<4> = H oder CH3, wenn X = CH3 R<5> = H, C1-C6-Alkyl, C5-C6-Cycloalkyl, Benzyl R<7> = H, C1-C6-Alkyl, C5-C6-Cycloalkyl, Benzyl R<6> = H, C1-C3-Alkyl, OH R<8> = H, C1-C8-Alkyl, C5-C6-Cycloalkyl, Cyclohexenyl X = H, OH, C1-C6-Alkyl, C5-C6-Cycloalkyl, Benzyl. Die Benzylphenole sind als Stabilisierungsmittel für Kautschuk geeignet. New benzylphenols of the general formula <IMAGE> in which the substituents X and R¹ to R <7> have the following meaning: R¹ is a single bond or a divalent radical such as. B. <IMAGE> R² = H, C1-C12-alkyl, C5-C6-cycloalkyl, benzyl, α-methylbenzyl, α, α-dimethylbenzyl R³ = H, CH3, phenyl R <4> = H, CH3, where R³ = R <4> = H or CH3 if X = CH3 R <5> = H, C1-C6-alkyl, C5-C6-cycloalkyl, benzyl R <7> = H, C1-C6-alkyl, C5-C6 -Cycloalkyl, benzyl R <6> = H, C1-C3-alkyl, OH R <8> = H, C1-C8-alkyl, C5-C6-cycloalkyl, cyclohexenyl X = H, OH, C1-C6-alkyl, C5-C6 cycloalkyl, benzyl. The benzylphenols are suitable as stabilizers for rubber.
