Abstract: A method for producing dicarboxylic acid. The method includes: subjecting a raw material system including a cyclic olefin and a lower monocarboxylic acid to an addition reaction in the presence of an addition reaction catalyst to generate an intermediate product system including cyclic carboxylic acid ester; and subjecting the intermediate product system including cyclic carboxylic acid ester to a ring-opening and oxidation reaction in the presence of an oxidant and an oxidation catalyst to generate a corresponding dicarboxylic acid product. The addition reaction in the dicarboxylic acid synthesis route achieves a high single-pass conversion rate, and the selectivity of the corresponding cyclic carboxylic acid ester is high. The addition-oxidation synthesis route achieves faster reaction rates for both the addition reaction and oxidation reaction, and high yield of corresponding dicarboxylic acid product. The addition-oxidation based synthesis route is suitable for continuous, stable and large-scale production of corresponding dicarboxylic acid product.

Abstract: A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.

Abstract: Provided is a process for recovery of a functionalized compound reaction product comprising contacting (i) an oxidizing electrophile comprising a main group element, and (ii) a compound comprising at least one C—H bond, in an acidic medium to form a reaction milieu comprising a functionalized compound reaction product, contacting the reaction milieu with a water-immiscible organic solvent, separating the water-immiscible organic solvent from the reaction milieu, wherein the functionalized compound reaction product is dissolved in the water-immiscible organic solvent, and separating the functionalized compound reaction product and the water-immiscible organic solvent. The water-immiscible extraction solvent can be the same compound as the compound comprising as least one C—H bond, for example, propane or n-butane.

Abstract: A catalytic process for the methoxycarbonylation of olefins where formic acid is the CO source. The process includes the steps of forming a reaction mixture where methanol and formic acid are added at a volume ratio in the range from 1.55:0.45 to 1.1:09. The methanol-formic acid ratio enhances both the rate of conversion and methyl ester yield ether produced. The catalysts used is a palladium/benzene-base diphosphine ligand complex.

Abstract: Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.
