Abstract: PURPOSE:To obtain the subject compound having OH groups at both ends, by reacting a dihydric phenolic compound with diaryl carbonates at a specific ratio and removing the unreacted dihydric phenolic compound together with produced phenols from the system, thereby controlling the molecular weight of the product. CONSTITUTION:An aromatic polycarbonate oligomer having OH groups on >=90% of both ends can be produced by compounding a dihydric phenolic compound with diaryl carbonate at a molar ratio (phenol/carbonate) of >=1.2, especially >=1.5, reacting the components in the presence of a catalyst, removing the produced phenols (>=95mol% based on 2mol of the diaryl carbonate used in the reaction) from the system and, at the same time, removing a part or total of the unreacted dihydric phenolic compound from the system. The molecular weight of the oligomer can be controlled especially by removing the dihydric phenolic compound at a specific rate. The oligomer can be produced easily in high selectivity and the product is useful as a raw material for polymer.

Abstract: PURPOSE:To increase the efficiency of Y type zeolite as a catalyst for a liq. phase dehydration reaction by dealuminizing the zeolite and fluorinating the surface of the zeolite so as to obtain a prescribed ratio of SiO2 to Al2O3 and a prescribed fluorine content. CONSTITUTION:Y type zeolite is dealuminized and the surface of the zeolite is fluorinated to obtain fluorinated dealuminized Y type zeolite having 5.5-20 molar ratio of SiO2/Al2O3, 0.1-30wt.% fluorine content and a crystal structure similar to that of Y type zeolite. Fluorinated dealuminized Y type zeolite having proton exchange ability has an X-ray diffraction pattern shown by table 1. The pattern is formed by diffraction analysis with CuKalpha rays and the relative intensity of a diffracted ray at 6.4+ or -0.2 is represented by 100.

Abstract: PURPOSE:To obtain an epoxy resin which can be easily handled and can give a cured product excellent in a toughness such as bending strength and bending modulus, by reacting a specified oligocarbonate with an epihalohydrin and conducting the ring closure of the product through dehydrohalogenation by the addition of an alkali. CONSTITUTION:A bisphenol such as bisphenol A or bisphenol F is reacted with phosgene or diphenyl carbonate to obtain an oligocarbonate (A) of formula I (wherein R2-3 are each H, a lower alkyl or a phenyl, or they may be combined together to form a ring, X is a lower alkyl or a halogen, m is the number of substituents other than H and is 0-4, and n is 0-5). Component A is reacted with 2-20mol., per OH group of component A, of an epihalohydrin (B) of formula II (wherein R1 is H or an alkyl, and Y is a halogen) at 50-120 deg.C in an anhydrous state in the presence of a catalyst (C) such as quat. ammonium salt, and the product is subjected to ring closure through dehydrohalogenation by slowly adding thereto an alkali such as NaOH to obtain an epoxy resin of formula III.

Abstract: PURPOSE:To obtain the titled compound in high yield under a low pressure, by reacting carbon monoxide with hydrogen in the presence of a catalytic system consisting of a rhodium compound and a rhenium compound. CONSTITUTION:Carbon monoxide is reacted with hydrogen in the presence of a catalytic system containing a rhodium compound and a rhenium compound, e.g. ReCl3, ReO3 or NH4ReO4, preferably in an amount of give a ratio between the numbers of gram-atoms of rhenium in the rhenium compound and the rhodium in the rhodium compound of about 0.01-100, preferably 0.1-10, preferably about 150-300 deg.C to give the titled compound. The molar ratio (CO/H2) between the carbon monoxide and the hydrogen to be fed is usually about (2/1)-(1/5). A co- catalyst, e.g. an alkali metallic compound or ammonia, is preferably used in the catalytic system.
