Claims
- 1. A method for the stabilization of a long-chain unsaturated aliphatic ester, alcohol, ketone or hydrocarbon compound having at least 10 carbon atoms and at least one double bond in a molecule, which comprises admixing the compound with 2-(2′-hydroxy-5′-methylphenyl) benzotriazole and a phenolic compound as an antioxidant each in an amount in the range from 0.1 to 10% by weight based on the amount of the long-chain aliphatic unsaturated compound.
- 2. The method for the stabilization of a long-chain unsaturated aliphatic ester, alcohol, ketone or hydrocarbon compound as claimed in claim 1 in which the phenolic compound as an antioxidant is selected from the group consisting of tert-butyl hydroquinone, 2,5-di-tert-butyl hydroquinone and 2,5-di-tert-amyl hydroquinone.
- 3. The method for the stabilization of a long-chain unsaturated aliphatic ester, alcohol, ketone or hydrocarbon compound as claimed in claim 1 in which the amount of 2-(2′-hydroxy-5′-methylphenyl) benzotriazole is in the range from 1 to 5% by weight based on the amount of the long-chain unsaturated aliphatic compound.
