  • Patent number: 7759096
    Abstract: A process for enzymatic production of glyceride compositions, specifically industrially practicable production of triglycerides, including conjugated linoleic and linolenic acid triglycerides, and the compositions produced by such process. An enzymatic reaction zone is first utilized, in which a mixture of glycerol and fatty acids or fatty acid derivatives is reacted in the presence of an enzymatic catalyst to form 1,3 diglycerides. The mixture is then circulated through a second thermal rearrangement zone, maintained at a higher temperature, to promote rearrangement of the 1,3 diglycerides to 1,2 diglycerides. Triglycerides are produced by re-circulating the mixture through the enzymatic production zone.

  • Patent number: 6897327
    Abstract: A process to manufacture conjugated linoleic acid (CLA)-containing materials such as conjugated linoleic salts and acids that are enriched in desirable cis-9, trans-11- and trans-10, cis-12-CLA isomers and are low in certain undesirable isomers. The process generally entails isomerization of an alkyl ester of a linoleic acid-containing material at a temperature typically between about 90 to 140° C. to effectuate conjugation of the double bonds, followed by saponification of the resultant CLA-containing fatty acid ester to produce a CLA-containing fatty acid salt, optionally followed by neutralization of the CLA-containing fatty acid salt with an acid source to produce a CLA-containing fatty acid.

  • Publication number: 20030105352
    Abstract: This invention relates new and improved processes for the preparation of arylalkylsulfonic acids derived from aromatic or substituted aromatic molecules and AOS acid (generally a mixture of alkenesulfonic acid and sultones, produced from the sulfonation of alpha olefins). The invention involves the use of a superacid catalyst to effectuate the conversion of AOS acid and aromatic reactants to arylalkylsulfonic acid under substantially anhydrous conditions, whereby a substantial improvement in the rate of conversion of the reactants to arylalkylsulfonic acid and/or improvement in mono-alkylation selectivity is realized, as compared to methods of preparation previously disclosed. Also useful as an alkylation promoter is the arylalkylsulfonic acid reaction product itself, produced in situ or from a previous reaction (i.e., a self-catalyst heel).

  • Patent number: 5840985
    Abstract: Disclosed is a process for the preparation of primary, secondary and tertiary amines with high conversion and high selectivity via low pressure catalytic hydrogenation of unsubstituted, N-substituted, and N,N-disubstituted amides. Amide hydrogenation is conducted using a catalyst system comprising copper chromite and a nucleophilic reagent, in combination with hydrogen gas. The process allows for production of amines which may be directly used as chemical intermediates in the manufacture of surfactants, quaternary ammonium compounds, bactericides, disinfectants, lubricants, petroleum additives, ion exchange resins and the like, without the need of purification, such as distillation.
