Paragraph 0010; 0027; 0030-0032; 0035, (2019/10/01)
The invention discloses a preparation method of high-purity sodium pantoate. According to the method, beta-alanine and an alkali are adopted as raw materials for a reaction in a low-level alkanol solvent to obtain sodium beta-alaninate, the sodium beta-alaninate reacts with D-pantolactone in a low-level alkanol solvent to obtain a crude sodium pantothenate product, and the crude sodium pantothenate product is refined in 95% ethanol and crystallized to obtain sodium pantothenate. Sodium pantoate prepared by means of the method has the advantages that being uniform in particle size, good in fluidity, low in wettability, easy to operate, environmentally friendly, high in yield and purity and suitable for industrial production.

An atom-economical and environmentally friendly method to transform amino alcohols to amino acid salts using just basic water, without the need of pre-protection or added oxidant, catalyzed by a ruthenium pincer complex, is developed. Water is the solvent, the source of the oxygen atom of the carboxylic acid group, and the actual oxidant, with liberation of dihydrogen. Many important and useful natural and unnatural amino acid salts can be produced in excellent yields by applying this new method.

, (2008/06/13)
A process to manufacture a carboxylic acid salt is disclosed wherein an aqueous solution of a primary alcohol is contacted with a base hydroxide in the presence of an effective amount of a catalyst consisting essentially of an alkali resistant support, from about 0.05 wt. % to about 10 wt. %, based on the total weight of the catalyst, of an anchor metal is selected from the group consisting of platinum, palladium, ruthenium, and gold, and between about 1 wt. % and about 50 wt. %, based on the total weight of the catalyst, of an element selected from the group consisting of copper, cobalt, nickel, and cadmium combined with the anchor metal.
