Abstract: A nitrile compound or an amide compound is hydrolyzed in the presence of an inorganic acid or other acidic catalyst or an alkali metal hydroxide or other basic catalyst, and the by-produced ammonium salt of the acidic catalyst or the produced salt of a carboxylic acid and a base is electrodialysed to form an acid and ammonia or aqueous ammonia, or to form a base and ammonia. The obtained acid or base may be recycled as a catalyst for the hydrolysis of the nitrile compound or amide compound, and the obtained ammonia is reutilized as a nitrogen source for the nitrile compound or amide comound. Such amide compound may be produced by hydration of a nitrile compound in the presence of a manganese oxide.

Abstract: Nitrile compounds having a complicated structure (2-hydroxy-4-methylthiobutyronitrile, etc.) are converted into amide compounds at a high production efficiency with the use of novel microorganisms having a specific base sequence as the 16S rRNA gene base sequence. Examples of these microorganisms include Rhodococcus sp. Cr4 strain and Rhodococcus sp. Am8 strain.

Abstract: PROBLEM TO BE SOLVED: To obtain a new microorganism as a kind of microorganisms containing 16S rRNA gene having specific base sequences, having the ability to convert a nitrile to the corresponding amide in high production efficiency, and useful in e.g. producing an amide compound for producing feed additives, or the like. SOLUTION: The new kind of microorganism is e.g. Rhodococcus sp.Cr4 strain (FERM BP-6596), containing 16S rRNA gene having respective base sequences of formula I and formula II and having the ability to convert a nitrile to the corresponding amide, thus being useful in producing the corresponding amide compound from a nitrile such as a cyanohydrin of formula III (R1 is a hydrocarbon group or heterocyclic group optionally having substituent(s)). The Rhodococcus sp.Cr4 strain as the new kind of microorganisms has been afforded by isolation using an accumulation method by culture in a selective medium from the soil collected from a certain field soil in Okayama City, Okayama Prefecture, Japan.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for producing 1,6-hexanediol at a low cost by using cyclohexanone as a starting raw material. SOLUTION: In the method, 1,6-Hexanediol is produced by a catalytic reduction reaction of a crude ε-caprolactone fraction obtained from a reaction process of an organic peracid and/or hydroperoxide with cyclohexanone or a by-product fraction composed mainly of residual ε-caprolactone left after separating ε-caprolactone from the crude ε-caprolactone, by-produced oxycaproic acid, adipic acid and their oligomers as they are in the presence of a hydrogenation catalyst or after esterifying the fraction with an alcohol.

Abstract: PROBLEM TO BE SOLVED: To keep the catalytic activity over a long period and suppress the formation of by-products by reacting an acetylenic or olefinic unsaturated compound with carbon monoxide having low hydrogen content ion the presence of a carbonylation catalyst. SOLUTION: An acetylenically or olefinically unsaturated compound (preferably a 2-10C α-acetylenically or α-olefinically unsaturated compound) is carbonylated by reacting with carbon monoxide in the presence of a carbonylation catalyst. The reaction is carried out by using carbon monoxide having a hydrogen content of to 1×10 mol in terms of metallic atom and that of carbon monoxide is 1-5mol based on 1mol of the unsaturated compound.

Abstract: PURPOSE:To obtain one isomer of phenylpropionic acid useful as a drug economically, efficiently and in high purity, by dissolving an isomer mixture of a phenylpropionic acid in a solvent and carrying out crystallization. CONSTITUTION:An isomer mixture of a phenylpropionic acid shown by the formula (R is H, alkyl, alkenyl or aryl) is dissolved in a solvent (e.g. hexane, heptane, methanol, acetone, ethyl acetate, etc.). The concentration of the solution is ordinarily up to about 15wt%. After the dissolution, crystal is precipitated by methods of (i) changing temperature of the solution, (ii) adding a solvent such as water, etc., (iii) distilling away part of the solvent, etc., to give the aimed compound. When purity of the crystal is insufficient, the crystal is redissolved in the solvent and crystallization is repeated to improve purity.
