Title: Improvements in or relating to the stabilisation of brominated oils
Inventor: BECKTEL JACK MARTIN
IPC: C11B5/00
Filed: 1961-10-10
Abstract: A brominated oil, suitable as a weighting agent for citrus flavouring oils, is stabilised by a minor but sufficient amount of an epoxy-containing fatty material.  Proportions of from 0.08% to 5% based on the weight of the brominated oil of the epoxy-containing fatty material, providing at least 0.006% oxirane oxygen in the total composition of brominated oil and epoxy-containing fatty material, are suitable.  The epoxy-containing fatty material may be added to the brominated oil prior to heat deodorisation to protect it from accelerated degradation. Brominated Oils: brominated animal, vegetable and marine glycerides, brominated cotton-seed, lard, olive, corn, sesame, soybean, safflower seed and apricot kernel oils, brominated unsaturated higher aliphatic alcohols and unsaturated aliphatic acid esters of mono- and dihydric alcohols such as brominated methyl oleate, partially brominated oils such as partially brominated soybean oil, and mixtures of these of a desired specific gravity.  Epoxy-containing fatty material: epoxidised soybean, cotton-seed, linseed, rapeseed, menhaden, peanut, lard and safflower oils, epoxidised tallow, methyl or ethyl epoxy stearate, epoxidised glycerides, tri-epoxy stearin, and other epoxidized animal, vegetable or marine oils, or mixtures of these.  Examples are directed to the stabilisation of a mixture of 1 part soybean oil and 5 parts cotton-seed oil, which had been brominated at low temperature, and to the colour improvement resulting from the addition to brominated sesame oil that had been stored for 18 months of epoxidised soybean oil.ALSO:A brominated oil, suitable as a weighting agent for citrus flavouring oils, is stabilized by a minor but sufficient amount of an epoxy-containing fatty material.
