Abstract: PURPOSE:To produce pentenoic acid esters from 1,3-butadiene, an aliphatic alcohol and carbon monoxide with industrial advantage by using a new catalyst system composed of a cobalt complex prepared by addition of a small amount of an aminopyridine. CONSTITUTION:A new catalyst system composed of a cobalt complex such as cobalt diacetylacetonate, cobalt bromide or a cobalt carbonyl complex and a small amount of an aminopyridine is used. Carbon monoxide, 1,3-butadiene of formula CH2=CH-CH=CH2 and an aliphatic alcohol of formula ROH (R is aliphatic) are brought into contact with the catalyst system to synthesize the objective pentenoic acid ester of formula CH3CH=CHCH2COOR, CH3CH2CH: CHCOOR or CH2=CHCH2CH2CO0R. As the aliphatic alcohol, a 1-10C aliphatic alcohol is preferable. The aminopyridine is used preferably in an amount of 0.005-0.3mol based on 1mol 1,3-butadiene. By using the new catalyst system, pentenoic acid esters can be produced with industrial advantage.

Abstract: PURPOSE:To selectively prepare a compound useful as a raw material for preparing agricultural chemicals by reacting a hydroxyaniline with an alkylcarbonate compound. CONSTITUTION:A hydroxyaniline (e.g. m-aminoaniline) is reacted with an alkylcarbonate compound (e.g. dimethylcarbonate) in the presence of a catalyst such as a basic compound or metal compound in the absence of a solvent or in a solvent such as methanol at room temperature-250 deg.C under ordinary pressure-50 atmospheres for 0.1-50hrs to provide the objective compound. The catalyst is preferably an alkali metal compound, especially the metal itself, alkoxy compound, hydroxide, hydride or amide thereof. The hydroxyaniline and the alkylcarbonate compound are used in a molar ratio of 0.2-20, and the catalyst and the hydroxyaniline are also used in a molar ratio of 0.005-10.

Abstract: PURPOSE:To obtain the subject polymer from an inexpensive raw material with a simple process in a short time in high efficiency by reacting an aliphatic diol compound with dimethyl carbonate in two steps under respective specific conditions. CONSTITUTION:The objective polymer can be produced by reacting an aliphatic diol compound (e.g. 1,4-butanediol) with dimethyl carbonate in the presence of a catalyst (preferably an alkali metal compound, etc.) in a closed reaction system at a reaction temperature of 130-250 deg.C while keeping the molar ratio of dimethyl carbonate/aliphatic diol compound in the reaction system to 0.5-1.7, removing the methanol produced by the above reaction from the system and heating the reaction mixture under reduced pressure to perform the 2nd-stage reaction while removing the produced methanol from the reaction system. The 2nd stage reaction is carried out preferably at 150-250 deg.C under a pressure of

Abstract: PURPOSE:To obtain compounds useful as an intermediate for dyes, high polymers, ultraviolet absorbers, synthetic resin stabilizers, color formers, medicines, etc., by reacting phenols with aromatic carboxylic acids in the presence of a catalyst of a tin compound. CONSTITUTION:Phenols are reacted with aromatic carboxylic acids in the presence of a tin compound expressed by the formula (R to R are alkyl or aryl; X and X are hydroxy, alkoxy or aryloxy) used as a catalyst in or without a solvent, such as benzene, at 100-400 deg.C for 10min-40hr to afford aryl aromatic carboxylates. The tin compound catalyst is used in an amount of 1X10 to 1X10 molar ratio based on the aromatic carboxylic acids and the phenols are used in an amount of 0.1-100 molar ratio based on the aromatic carboxylic acids. Side reactions due to high temperatures can be suppressed and selectively and reaction rate can be improved by the afore-mentioned method to afford the objective high-purity compounds excellent in hue.
