摘要： To recover amino acids from raw sugar juice, as obtained in beet extraction, the juice is treated with acid or with lime to coagulate impurities which are separated off. The juice may be treated before or after coagulation with a pectin-cleaving enzyme. The juice so pretreated can be directly passed through a strong cation exchanger and a weak anion exchanger whereby the amino acids are adsorbed. Switchover to a new cation exchanger is initiated when betaine flows out the column. Elution is effected, preferably with an ammonium compound, and eluate is collected, preferably each fraction being enriched in a different amino acid. The sugar juice may be concentrated and crystallized in known manner and is of comparatively high purity.

摘要： Oxyethylene dicarboxylic acid alkali metal salts are prepared from the corresponding oxydiethylene or polyoxyethylene diol and an aqueous alkali metal hydroxide in the presence of a catalytically effective amount of a nickel-copper-chromia catalyst at temperatures from about 200 to 300.degree. C. and pressures sufficient to maintain the reactants and products substantially in liquid phase. Preferably, the disodium salt of oxydiacetic acid is prepared by the oxidation of diethylene glycol with an aqueous sodium hydroxide solution in the presence of a catalytically effective amount of the nickel-copper-chromia catalyst. The disodium oxydiacetate can be readily precipitated from the crude reaction mixture by addition of a mixture of methoanol-isopropanol with subsequent filtration.

摘要： Disclosed herein are improved methods for making diglycolic acid, dipropionic acid and the salts thereof. The methods include the use of diethylene glycol, dipropylene glycol, or chloroacetic acid as starting materials. In the preferred method for manufacturing diglycolic acid, diethylene glycol is oxidized under controlled temperature conditions and in the presence of a minor amount of water. Ozone is the preferred oxidizing agent. In one method for manufacturing dipropionic acid, dipropylene glycol is oxidized while in the other process diethylene glycol is reacted with hydrogen cyanide and the resulting nitrile is reacted with sodium hydroxide.
