摘要： PURPOSE: To obtain the titled amino acid useful as a drug, feed, etc. in high yield, by reacting β-chloroalanine with an alkali metal or ammonium polysulfide in an aqueous medium.
CONSTITUTION: β-Chloroalanine is reacted with an alkali metal or ammonium polysulfide (e.g., sodium sulfide) in an aqueous medium or organic solvent (e.g., n-hexane) to give cystine, which is reduced to give cysteine. The reaction is usually carried out in a molar ratio of β-chloroalanine to the polysulfide of the alkali metal, etc. to (1: 1.0W about 5.0), the reaction temperature is preferably 5°CW the boiling point of the reaction solution and 20W100°C. β-Chloroalanine is almost completely converted into cystine and cysteine (or its S-alkali metal or ammonium salt), and cysteine and its salt is easily converted into cystine by acid treatment or oxidation reaction.

摘要： PURPOSE:To obtain alkylene glycol monoether, by reacting an alkylene oxide with an alcohol in the presence of clay of the montmorillonite structure comprising Al, Cr, Mn, Fe, etc. which replace substitutable cations. CONSTITUTION:An alkylene glycol monoether is obtained by reacting an alkylene oxide with an alcohol in the presence of clay comprising 50% or more of the montmorillonite structure, e.g. acid clay, and Al, Cr, Mn, Fe, Sn, thorium, etc., which replace substitutable cations, prepared through the usual agitation of the suspended clay or flow treatment of a column packed with the clay. This reaction is preferably carried out in the liquid phase under pressure by passing the raw materials through a fixed bed. EFFECT:The catalyst having a high activity and selectivity maintains its performance stably for a long time. USE:A water-soluble high-boiling solvent and intermediate for industrial applications.

摘要： PURPOSE:The reaction of alpha-amino-beta-halogenopropionitrile with a carbonate or bicarbonate gives 2-oxo-4-cyano-oxazolidine and the product is hyrolyzed without isolation to achieve industrially advantageous production of serine. CONSTITUTION:alpha-Amino-beta-halogenopropionitrile or its mineral acid salt is allowed to react with a carbonate or bicarbonate in water or an aqueous organic solvent such as ethanol to give 2-oxo-4-cyano-oxazolidine, then the product is, without isolation, subjected to acidic or basic hydrolysis to give serine. Since the isolation of 2-oxo-4-cyano-oxazolidine is unnecesary, the yield of the process is high. The amount of the carbonate or bicarbonate used is 1.5 to 10mol times in the former and 2.0-1.0mol times in the latter. Too high molar amounts are not desirable, since side-reactions occur.
