A stigmasterol-rich phytosterol composition is prepared wherein the composition comprises at least 50% stigmasterol, based on the total weight of phytosterols, no more than 1000 ppm water, no more than 50 ppm ethanol, and wherein stigmasterol is at least 98% in the anhydrous form. A ready-to-freeze beverage is provided comprising the stigmasterol-rich composition and water, with optional additives. A frozen beverage is prepared from the ready-to-freeze beverage as a pourable slush. There are further provided processes to prepare the ready-to-freeze beverage and the frozen slush beverage.

Stigmasterol-rich phytosterol composition and use

The invention is directed to a process of combining an aqueous solution of a fluoride with an aqueous solution of a host multi-valent metal salt and an aqueous solution of a salt forming a reactant mixture resulting in a precipitate of aqueously insoluble rare-earth doped multi-valent metal fluoride nanoparticles.

This invention relates to a continuous process for production of poly(trimethylene terephthalate), wherein gaseous 1,3-propanediol by product resulting from the process is condensed in a condenser, and a portion of the condensed by-product is recycled back into the process.

Continuous process for producing poly(trimethylene terephthalate)

This invention relates to a continuous process for production of poly(trimethylene terephthalate), wherein gaseous 1,3-propanediol by-product resulting from the process is condensed in a condenser, the total amount of any trimethylene terephthalate cyclic dimer and poly(trimethylene terephthalate) in the condensed by-product 1,3-propanediol is adjusted, and a portion of the condensed by-product is recycled to the condenser while another portion is recycled back into the process.

Continuous manufacture of poly(trimethylene terephthalate)

This invention relates to a continuous process for production of poly(trimethylene terephthalate), wherein gaseous 1,3-propanediol by product resulting from the process is condensed in a condenser, and a portion of the condensed by-product is recycled to the condenser while anther portion is recycled back into the process.

Poly(trimethylene therephthalate) continuous manufacturing process

The present invention relates to a high yield process to prepare high purity crystalline glycolic acid using a multi-loop crystallization process characterized by high liquid and/or solid recycle, said process suitable for large scale purification and producing high purity glycolic acid with low diglycolic acid content.

Multi-stage glycolic acid crystallization

This invention relates to a novel system for making uniform crystals. The system, by virtue of the nature of its crystal product, is useful in various chemical, pharmaceutical, agricultural, and biotechnology applications. The invention features physically separated and controlled crystal nucleation and growth zones useful in industrially scaled crystallization processes. The invention also provides a method to preferentially nucleate and crystallize a desired category of crystal structure (enantiomer, solvate, polymorph) of non-chiral and chiral compounds.

Apparatus and process used in growing crystals

A process that can be used to produce NaCN is provided. The process comprises contacting hydrogen cyanide with sodium hydroxide solution to produce a NaCN solution and crystallizing the NaCN solution wherein the process is carried out in the presence of an acid or a metal salt of the acid in which the acid has a pKa&#x2266;4.4. The NaCN crystals can be separated from the slurry and dried.

Sodium cyanide process

A method for improving abrasion resistance of sodium perborate tetrahydrate crystals prepared by reacting sodium metaborate with hydrogen peroxide in an aqueous slurry crystal growth medium, the improvement including highly supersaturating the aqueous slurry crystal growth medium. Also, an agent such as an excess of caustic may be added to the aqueous crystal growth medium to limit the growth rate of individual crystals.
