Disclosed is a method of making hydrogenated metathesis products comprising the steps of: (a) providing a metathesis composition; (b) providing a metathesis catalyst comprising a transition metal; (c) metathesizing at least a portion of the metathesis composition in the presence of the metathesis catalyst to form a first composition comprising one or more metathesis products and a transition metal; (d) hydrogenating at least a portion of the first composition in the presence of a hydrogenation catalyst to form a second composition comprising one or more hydrogenated metathesis products, transition metal, and hydrogenation catalyst; and (e) removing at least a portion of the hydrogenation catalyst from the second composition, wherein the removal of the hydrogenation catalyst removes at least a portion of the transition metal of the metathesis catalyst from the second composition.

Phosphate rock is reacted with phosphoric acid to produce monobasic calcium phosphate. Monobasic calcium phosphate is reacted with ammonium carbonate to produce ammonium phosphate. Dibasic calcium phosphate is also produced as a by-product when monobasic calcium phosphate reacting with ammonium carbonate. The dibasic calcium phosphate is reacted with sulfuric acid to produce phosphoric acid. The phosphoric acid is used to react with phosphate rock. Ammonium sulfate or ammonium hydroxide may be used instead of ammonium carbonate. Phosphate other than ammonium phosphate can be produced if calcium phosphate is reacted with x-y to produce x-phosphate, where x is lithium, sodium, ammonium or potassium and y is carbonate, bicarbonate hydroxide or sulfate.

Process for producing high purity phosphates

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

The techniques for processing lactic acid/lactate salt mixtures are provided. Preferred mixtures for processing are obtained from fermentation broths, preferably from fermentation processes conducted at a pH of 4.8 or lower. The techniques generally concern the provision of separated lactic acid and lactate streams, from the mixtures. Preferred techniques of separation and processing of each of the streams are provided.

Lactic acid processing; methods; arrangements; and, products

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.
