A method for recovering a composition enriched in 3-hydroxypropionic acid from a fermentation broth comprising 3-hydroxypropionic acid and/or salts thereof comprises the steps of: (a) providing the fermentation broth having a pH of from about 2 to about 8 comprising: 3-hydroxypropionic acid and/or salts thereof, (b) acidifying the fermentation broth; (c) reducing the total sulfate ion and phosphate ion (d) distilling the resulting reduced ion aqueous solution and (e) recovering the product.

Recovery of 3-hydroxypropionic acid

A method for recovering a composition enriched in 3-hydroxypropionic acid by providing the fermentation broth, acidifying the fermentation broth; reducing the total sulfate ion and phosphate ion concentration of the resulting aqueous solution to produce a reduced ion aqueous solution; distilling the resulting reduced ion aqueous solution and recovering the resulting aqueous distillation product comprising 3-hydroxypropionic acid.

Methods of manufacturing derivatives of &#x3b2;-hydroxycarboxylic acids

Disclosed is a process for separating and recovering 3-hydroxypropionic acid from an aqueous solution comprising 3-hydroxypropionic acid and acrylic acid, comprising counter current extracting the aqueous solution with ethyl acetate extractant. Further disclosed is a process for separating and recovering 3-hydroxypropionic acid and acrylic acid from an aqueous solution comprising 3-hydroxypropionic acid and acrylic acid.

Process for separating and recovering 3-hydroxypropionic acid and acrylic acid

Processes for preparing carboxylic acids and derivatives thereof in which an ammonium salt of the carboxylic acid is heated in the presence of an organic reagent to split the salt and form the acid or, where the organic reagent is an esterifying agent, the corresponding ester. Both the acid and the ester may be dehydrated to form unsaturated counterparts.

Process for preparing carboxylic acids and derivatives thereof

Disclosed is a process for hydrogenating 3-hydroxypropionic acid, or esters thereof, or mixtures of the acid and the ester, in a liquid phase, in the presence of a ruthenium catalyst, alone, or in combination with at least one or more additional metal catalyst wherein the metal is molybdenum, tungsten, titanium, zirconium, niobium, vanadium, chromium, or mixtures of the metals.

Process for preparation of 1,3-propanediol

A method of preparing purified ester compositions is provided. The process can be utilized to isolate and purify monoglycerides and propylene glycol monoesters, to advantage. It can also be used to isolate preferred diester products. The invention also concerns equipment for conduct of the processes, provision of preferred food additives, and provision of preferred food industry compositions. The process generally involves use of liquid-liquid extractions, to advantage.
