A process comprising subjecting a composition comprising an alpha- or beta-hydroxycarboxylic acid, water, an extraction solvent, and an acid catalyst to extractive dehydration to form an unsaturated carboxylic acid product.

Extractive dehydration process

Disclosed are processes and apparatuses for producing a crystalline product. The processes and apparatuses may extend the operational time of an evaporative crystallizer by providing an internal volume or large deposit inventory for fouling deposits to reside without impacting the unit operation.

Process and apparatus for forced circulation evaporative crystallization with large deposit inventory

A process for converting tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone. A process for removing a tertiary chlorinated hydrocarbon impurity from 1,3-dichloro-1-propene involves contacting a mixture containing the 1,3-dichloro-1-propene and the tertiary chlorinated hydrocarbon impurity with a dehydrochlorination catalyst effective to catalyze a conversion of the tertiary chlorinated hydrocarbon impurity to a corresponding unchlorinated or less-chlorinated unsaturated hydrocarbon and hydrogen chloride and distilling the 1,3-dichloro-1-propene to produce a purified cis-1,3-dichloro-1-propene fraction and a purified trans-1,3-dichloro-1-propene fraction.

Selective dehydrohalogenation of tertiary halogenated hydrocarbons and removal of tertiary halogenated hydrocarbon impurities from a halogenated hydrocarbon product

A process for conducting equilibrium-limited chemical reactions that produce water as a reaction product. Specifically, a process that uses a reactive chromatography unit (RCU) to improve the efficiency of equilibrium-limited reactions, such as a process for reacting glycol ether (GE) and carboxylic acid (CA) to form water and glycol ether ester (GEE). The process includes supplying GE and CA to the RCU, where one of either the CA or the GE is in a stoichiometric deficit relative to the other reactant. The reactant in the stoichiometric deficit reacts in the presence of the catalyst in the RCU to form a mixture of GEE and water. A raffinate is separated from the mixture using the separation media of the RCU contains at least the GEE. An extract separated from the mixture using the separation media of the RCU contains at least the water.

Process for equilibrium-limited reactions

The present disclosure provides for a process for an equilibrium limited reaction using reactive chromatography unit (RCU) in which a first organic donor reactant (FODR) and a second organic acceptor reactant (SOAR) react to form a product mixture of a first acceptor product (FAP) and a second donor co-product (SDCP). The equilibrium-limited reaction does not produce water. The RCU has separation media to separate the product mixture into a raffinate and an extract. The FODR is in a stoichiometric deficit relative to the SOAR for the equilibrium limited reaction, so that the SOAR acts as the eluent for both the raffinate and the extract, and so as not to produce an azeotrope of FODR and the SDCP in the extract.

Reactive chromatography process for equilibrium-limited reactions

Methods and systems for producing high purity 3-hydroxypropionic acid (3-HP) from an aqueous medium, such as a fermentation broth, are described. Aqueous 3-HP solution can be purified by flash evaporation wherein the 3-HP is vaporized at an elevated temperature without conversion to acrylic acid. This process can be integrated with downstream processes for producing other chemical and consumer products.

A process for converting a tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone.
