Continuous processes for making ethylene glycol form aldohexose-yielding carbohydrates are disclosed which enhance the selectivity to ethylene glycol.

Continuous processes for the highly selective conversion of aldohexose-yielding carbohydrate to ethylene glycol

Continuous processes for making propylene glycol from ketose-yielding carbohydrates are disclosed which enhance the selectivity to propylene glycol.

Continuous processes for the highly selective conversion of sugars to propylene glycol or mixtures of propylene glycol and ethylene glycol

A continuous process for converting carbohydrates to ethylene and propylene glycol. The carbohydrates are mixed with water and passed through a reactor at a temperature that hydrolyzes the carbohydrate mixture at least partially to monosaccharides. The reactor has a first zone comprising a retro-aldol catalyst and a second zone comprising a reducing catalyst. The aldose is converted in the first zone into glycolaldehyde by the retro-aldol catalyst and the glycolaldehyde, in the presence of hydrogen, is converted to ethylene glycol in the second zone of the reactor. The reaction products are removed from the reactor and the ethylene glycol is recovered. The selectivity to propylene glycol can be enhanced via feeding ketose as the carbohydrate.

Process for the continuous production of ethylene glycol from carbohydrates

The present application provides a method for producing an beta-lactone product. The method includes the steps of: reacting an epoxide, a solvent with a carbonylation catalyst and carbon monoxide to produce a reaction stream comprising a beta-lactone then separating a portion of the beta-lactone in the reaction stream from the solvent and carbonylation catalyst to produce: i) a beta-lactone stream with the beta-lactone, and ii) a catalyst recycling stream including the carbonylation catalyst and the high boiling solvent; and adding the catalyst recycling stream to the feed stream.

Process for beta-lactone production

Processes that, make nitrogen-containing compounds include converting succinic acid (SA) or monoammonium succinate (MAS) derived from a diammoniurn succinate (DAS)- or MAS-containing fermentation broth to produce such compounds Including diammobmane (DAB), succinic dinitrile (SDN), succinic amino nitrile (SAN), succinamide (DAM), and related polymers.

Processes for producing butanediol (BDO), diaminobutane (DAB), succinic dinitrile (SDN) and succinamide (DAM)

Continuous flow systems and methods produce succinic anhydride by a double carbonylation of ethylene oxide with carbon monoxide and at least one catalyst. In some embodiments, the double carbonylation occurs using a single catalyst. In other embodiments, a first catalyst is used to promote the first carbonylation, and a second catalyst different from the first catalyst is used to promote the second carbonylation. The succinic anhydride is isolated from the product stream by crystallization and the catalyst is recycled to the reaction stream.

Succinic anhydride from ethylene oxide

An enhanced process for the production of a dianhydrosugar, such as isosorbide, from the corresponding sugar alcohol is described. The sugar alcohol is combined with an acid catalyst and reacted at elevated temperatures and at atmospheric pressure, eliminating the need for a vacuum. High selectivity and yields are achieved.

Processes for producing caprolactam and derivatives thereof from fermentation broths containing diammonium adipate or monoammonium adipate

Processes that make nitrogen-containing compounds include converting succinic acid (SA) or monoammonium succinate (MAS) derived from a diammonium succinate (DAS)- or MAS-containing fermentation broth to produce such compounds including diaminobutane (DAB), succinic dinitrile (SDN), succinic amino nitrile (SAN), succinamide (DAM), and related polymers.

Processes for producing diaminobutane (DAB), succinic dinitrile (SDN) and succinamide (DAM)

A process for making MAA from a clarified DAA-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes MAA, at least some DAA, and at least about 20 wt. % water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a DAA-containing liquid portion in contact with a MAA-containing solid portion that is substantially free of DAA; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.

Processes for producing monoammonium adipate and conversion of monoammonium adipate to adipic acid

Processes for producing nitrogen containing compounds include producing hexamethylenediamine (HMD), adiponitrile (ADN), adipamide (ADM) and derivatives thereof from adipic acid (AA) obtained from fermentation broths containing diammonium adipate (DAA) or monoammonium adipate (MAA).
