    Abstract: A process for preparing a conjugated linoleic acid (CLA) material that is enriched in the cis 9, trans 11 (rumenic acid) CLA isomer. The process involves subjecting a material containing at least 75 weight % CLA moieties to an enzymatic conversion, wherein the enzyme has the ability to discriminate between the cis 9, trans 11 and trans 10, cis 12 isomers. The enzyme is advantageously a lipase derived from Candida rugosa . The resulting CLA product stream is distilled to separate the free fatty acid fraction from the glyceride fraction. The recovered free fatty acid fraction contains about 55 weight % to about 70 weight % of the cis 9, trans 11 isomer (rumenic acid), and has a weight ratio of cis 9, trans 11 isomer to trans 10, cis 12 isomer of at least 3.5:1. The material enriched in rumenic acid may be used in foods, particularly infant formulas, or in food supplements or in pharmaceutical compositions.

    Abstract: N-Acyl amino acid salt compositions and an improved process for making them from fatty alkyl esters are disclosed. The process comprises reacting a fatty alkyl ester with an amino acid salt in the presence of an alkoxide catalyst at a pressure of at least 5 psig. At least 1 0 mole percent of catalyst is used based on the amount of fatty alkyl ester used as a reactant. Pressure and a minimum level of alkoxide catalyst are needed to give high fatty alkyl ester conversions and good yields of the desired N-acyl amino acid salt. The resulting N-acyl amino acid salt compositions have low color, an acceptable level of fatty acid soaps, and a small proportion of di-acylated by-products. Single-phase mixtures produced by combining various amino acid salts with glycinates, or by using an excess of either the fatty alkyl ester or amino acid salt, promote high conversions when the mixtures are reacted to give the desired N-acyl amino acid salt.

    Abstract: Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C 10 -C 12 monounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.

    Abstract: A process for making bis(aryloxyalkyl)terephthalates useful as antiplasticizers for thermoplastic polyesters is disclosed. Dimethyl terephthalate is reacted with an excess of an aryloxyalkanol in the presence of a condensation catalyst to produce an intermediate mixture comprising a bis(aryloxyaIkyl)terephthalate, a mono(aryloxyalkyl)terephthalate, and unreacted aryloxyalkanol. This mixture continues to react at reduced pressure while unreacted aryloxyalkanol is removed and the mono-ester content is reduced to less than 1 mole % based on the combined amounts of mono- and bis-esters. Both steps are performed substantially in the absence of oxygen. Additional unreacted aryloxyalkanol is then removed to provide a purified bis(aryloxyalkyl)terephthalate having an overall purity of at least 98 mole % and a yellowness index less than 10. Careful control over catalysis, exposure to air, and other process conditions enables the preparation of high yields of bis(aryloxyalkyl)terephthalates that have low color and other valuable attributes. A method of producing bis(aryloxyalkyl)terephthalate articles having improved compressive strength is also disclosed.
