  • Patent number: 8841470
    Abstract: Chemically-modified fatty acids are prepared by reacting epoxidized fatty acids, their esters or triglyceride oils with amines of cyclic or aromatic hydrocarbons. The fatty acid derivatives produced are of the formula: wherein R is an H, branched or straight chain alkyl or alkenyl group, aromatic-containing group, glycerol, or glyceride, R? is a C3 to C29 aliphatic chain comprising one or more of the derivatized methylene groups of the formula: wherein R1 and R2 are independently selected from the group consisting of H, cyclic hydrocarbons, substituted cyclic hydrocarbons, and aryl groups, with the proviso that only one of said R1 and R2 may be H. These fatty acid derivatives have utility as antiwear/antifriction additives for industrial oils and automotive applications.

  • Patent number: 8772517
    Abstract: A composition, which is suitable for the production of stilbene compounds, can be separated from tall oil. It contains esters of pinosylvin or pinosylvin derivatives and it is concentrated in relation to these. Preferably, the composition contains esters of pinosylvin monomethyl ethers, the acid part of which is formed of an inorganic acid or an organic acid, in particular an organic acid, which is present in the crude tall oil or which is generated from this oil during the process of refining it. Typically, such acids are fatty and resin acids and lower alkane acids. With the invention, it is possible to generate, at an industrial scale, product fractions, and the pinosylvin compounds which are separated from the fractions can be used as such or they can be further modified by means of different chemical methods.

  • Patent number: 5440059
    Abstract: A novel method for preparing an aryl-substituted fatty acid or fatty ester is disclosed. According to the method, an olefinic composition selected from among mono-unsaturated fatty acids, mono-unsaturated fatty esters and mixtures thereof is introduced to a reaction zone comprising a liquid aromatic hydrocarbon and a catalytic amount of a clay catalyst to produce a reaction that is allowed to proceed for a time and at a temperature sufficient to produce a reaction product comprising a desired yield of aryl-substituted fatty acid or fatty ester. Preferably, the introduction of the olefinic composition is conducted slowly, such as over a period of one to four, more preferably, two to four, hours. Related methods and compositions, including xylylstearic acid, are also disclosed.

  • Patent number: 5306730
    Abstract: A botulinum toxin neutralizer comprising at least one fatty acid having the number of carbon atoms of at least 12. Such a fatty acid may be any of saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, nonadecanoic acid, arachidic acid, and behenic acid or any of unsaturated fatty acids such as oleic acid. The toxin neutralizer acts as if it were an antagonistic receptor for botulinum toxin and, when encountering botulinum toxin in human body, directly combines with the toxin and disables the toxin from combining with the neuromuscular tissues of human body to prevent the outbreak of botulism. The toxin thus neutralized and affixed to the botulinum toxin neutralizer is excreted from the human body. The botulinum toxin neutralizer can be manufactured easily and economically from a naturally occurring glyceride and is thus far less costly then the known antitoxin of ganglioside GT1b produced from bovine brain.
