Abstract: The present invention provides a pretreatment method to reduce saturated fatty acids of fatty acids used as feedstock when preparing ester polyols. The range of feedstock includes non-fractionated to fully fractionated feedstock. Performing some fractionation by distillation of the fatty acids derived from feedstock eliminates the need to fractionate the various ozone esters from each other before esterification. Further, the approach of the present invention is more economical and efficient than the conventional method of fractionation by crystallization.

Abstract: Solvent-less methods to convert oil derivatives, and modified oils to highly functionalized esters, ester polyols, amides, and amide polyols. The products can be used to make polyurethane and polyester films and foams.

Abstract: A process for the preparation of new polyols and polyesters from a natural oil or other unsaturated fatty acid esters is described. The process involves ozone cleavage of double bonds in the fatty acid chains of the oils along with coupling of a hydroxylated compound such as a mono-alcohol, a diol, or a polyol to the cleaved ends of the molecules resulting from the cleavage with a base. The resulting polyols and polyesters are as intermediates for polymers.

Abstract: The present invention relates generally to polymers and monomers derived from agricultural feedstocks, and more particularly to methods for the production of monomers from renewable agricultural resources such as feedstocks, for example canola, flax and tallow, and polymers, in particular polyurethanes produced from monomers derived from such feedstocks. The present invention also relates to novel processes for the production of short-chain alcohols, as well as hydroxyl wax esters, from renewable feedstocks. An improved apparatus for carrying out ozonolysis reactions is also disclosed.

Abstract: A process for carrying out a multi-phase reaction in a continuously operated tube reactor operated according to the counter current principle in which reactor components of a liquid phase flowing downwards as a thin film in said tube reactor and components of a continuous gas flowing upward in said tube reactor are brought to material transfer, or reaction respectively. The gas phase is pulsed, by repeated temporary pressure lowering at the gas entry into said tube reactor and/or repeated temporary pressure increase at the gas exit from said tube reactor, to counteract film thickness growth and liquid phase stagnation.

Abstract: A method for refining virgin plant oil and/or waste vegetable oil into fuel, preferably diesel engine fuel, wherein said method comprises the steps of heating the oil supplying water and/or ozone mixing the oil with water and/or ozone and agitating the mixture of oil and water and/or dissipating the ozone.

Abstract: A method of preparing an ester of a carboxylic acid functionalized with a moiety selected from the group consisting of halides, sulfonates, ethers, hydroxyl, amines, and aldehydes, said method comprising: (a) providing either a carboxylic acid having a vinyl group or an ester thereof; (b) functionalizing the vinyl carbon closest to the carboxyl group with said moiety, wherein said functionalizing comprises cleaving said vinyl group.

Abstract: Pure azelaic acid is obtained by working up a reaction mixture containing C.sub.1-18 monocarboxylic acids, mainly pelargonic acid, and C.sub.4-16 dicarboxylic acids, mainly azelaic acid, obtained from the ozonolysis of oleic acid or a starting mixture containing oleic acid. All but <2% by weight of the monocarboxylic acids and part of the dicarboxylic acids with a chain length of <C.sub.9 and >C.sub.9 are separated off to obtain a prepurified product containing more than 75% by weight of oleic acid and the prepurified product is concentrated to more than 90% by weight of oleic acid in several process steps. In a first process step (1), the dicarboxylic acids with chain lengths of <C.sub.9 present in the prepurified product are removed as first runnings by fractional distillation. In a second process step (2), the bottom product obtained is reacted with water to split carboxylic anhydrides present in the bottom product.

Abstract: A process of preparing alkali metal N-acyl amino acids, especially sodium N-acyl sarcosinates. The process of the invention eliminates the use of phosphorus trichloride or thionyl chloride and carboxylic acid chlorides. The process involves reacting the alkali metal N-acyl amino acid directly with a fatty acid at elevated temperatures with constant removal of water generated in the reaction.

Abstract: A carboxylic acid is made by contacting an organic compound having at least one olefinic bond with ozone to form a mixture of ozonization products; contacting the mixture of ozonization products with oxygen to form a mixture of oxidation products; contacting the mixture of oxidation products with oxygen in the presence of an effective amount of a catalyst selected from the group consisting of a manganese-exchanged X-zeolite, a manganese-exchanged Y-zeolite, a manganese-exchanged A-zeolite, or a combination thereof to form said carboxylic acid.
