Filed: 1990-01-30
Abstract: PURPOSE:To advantageously separate and purify DL-serine by hydrolysis of a product of the (oxidative) dehydrogenation-Strecker reaction of ethylene glycol followed by ion-exclusion chromatography twice with a neutralization interposed therein using a strong-acidity cation exchange resin. CONSTITUTION:A reaction liquid containing glycolaldehyde formed by dehydrogenation or oxidative dehydrogenation of ethylene glycol is directly put to Strecker reaction without the separation and purification of said intermediate difficult in such separation and purification, and the resulting reaction product is hydrolyzed with a strong base, and then ammonia is recovered from an aqueous solution containing the resultant DL-serine alkali salt. Thence, the above- mentioned aqueous solution is put to ion-exclusion chromatography using a strong-acidity cation exchange resin, and the resulting DL-serine fraction is neutralized to ca. the isoelectric point of serine followed by ion-exclusion chromatography again to simply eliminate unreacted raw materials and/or inorganic salts contained, thus industrially obtaining at a low cost high-purity DL-serine useful for amino acid infusion solutions, etc.

Filed: 1994-02-17
Abstract: PURPOSE:To provide an alarm device for drop of tire air pressure to notify a driver of a vehicle having the air-supplied tires at the right and left sides of an axle of a fact that the difference of air pressure is produced among these tires.
