Abstract
An antioxidant composition comprising 65-80% of 2, 6-di-tert butyl phenol, 10-15% of 2, 4, 6-tri-tert butyl phenol and 25-5% of 2-tert butyl phenol, the proportions being by weight, may be added to natural or synthetic rubber, polyethylene or polypropylene. Specification 798,438 is referred to.ALSO:An antioxidant composition comprises 65-80 % of 2, 6-di-tert butyl phenol, 10-15 % of 2, 4, 6-tri-tert. butyl phenol and 25-5 % of 2-tert. butyl phenol, the proportions being by weight. A suitable composition of this type may be prepared by alkylation of phenol with isobutylene at elevated temperature and pressure in the presence of an aluminium phenoxide catalyst. The composition may be added to gasoline, diesel fuel, mineral lubricating oil, lubricating grease, petroleum wax, rubber, synthetic rubber, polyethylene, polypropylene, and edible fats and oils. Specification 798,438 is referred to.ALSO:An antioxidant composition comprising 65-80% of 2,6-di-tert butyl phenol, 10-15% of 2,4,6-tri-tert. butyl phenol and 25-5% of 2-tert. butyl phenol, the proportions being by weight, may be added to gasoline, diesel fuel, mineral lubricating oil, lubricating grease, petroleum wax or edible fats or oils. Gasolines, to which the antioxidant composition may be added, may comprise straight-run components, thermally or catalytically cracked stocks, polymer blending stock, reformed gasoline, butane or pentane and may also comprise additional ingredients such as auxiliary solvents, organo-lead antiknock agents (e.g. lead tetra - alkyls), organic halogen - containing scavengers (e.g. alkylene dihalides, other halogen - substituted aliphatic or aromatic hydrocarbons, b ,b 1-dibromo-diisopropyl ether, b ,b 1 - dichlorodiethyl ether, ethyl - a - bromo - acetate, 1,1 - dichloro - 1 - nitroethane and 1 - bromo-3-hydroxypropane) and organic phosphorus compounds (e.g. phosphate esters, tri-(b - chloroprophyl) thionophosphate, di - xylyl phosphoramidate and trialkyl phosphines). Specification 798,438 is referred to.ALSO:An antioxidant composition comprising 65-80% of 2,6-di-tert butyl phenol, 10-15% of 2,4,6, - tri - tert. butyl phenol and 25-5% of 2-tert. butyl phenol, the proportions being by weight may be added to edible fats and oils as incorporated in the petroleum waxes used on paper coatings for food containers and food wrappings. Specification 798,438 is referred to.
