Abstract: The present invention relates to a process for the preparation, from e.g. anhydrovinblastine, of binary indole alkaloids effective as an anti-cancer drug, such as vinblastine, leurosidine, etc., wherein a trivalent iron source and hydride source are added in the presence of oxygen, thereby increasing a yield of an object compound. The yield of an object compound is improved still more by further addition, to the reaction system, of an oxalic acid ion source, malonic acid ion source, inorganic anion source, amino acid, etc.

Abstract: A solid catalyst for polymerizing an olefin is prepared from an organometallic compound, a fine-particle carrier, an aluminoxane, a compound of group IVB transition metal in periodic table, and an olefin polymer produced in a preliminary polymerization. The catalyst has a high polymerization activity and is capable of producing an olefin polymer having a narrow molecular- weight distribution. When the catalyst is used for producing an olefin copolymer, the resulting copolymer has both narrow molecular-weight distribution and composition distribution.

Abstract: In a first form, a process is provided for preparing phenol by converting acetone by-produced by the cumene process into isopropanol, and alkylating benzene with the isopropanol and optional propylene, thereby forming phenol without acetone by-product. And cumene is prepared by alkylating benzene in the presence of a zeolite catalyst using isopropanol or a mixture of isopropanol and propylene as an alkylating agent. Further provided is the continuous alkylation of benzene with isopropanol wherein a reaction mixture is divided into first and second portions, with the first portion being recycled to the reactor and the second portion being taken out as a reaction product.

Abstract: When a hydrophobic thermoplastic resin such as an olefin resin and a water-insoluble or non-water-swelling polymer containing a carboxylic acid salt group are melt-kneaded in the presence of water, phase inversion of forming a dispersion comprising water as the dispersion medium phase and resin particles as the dispersed phase is caused even if the amount of water is very small. If an anionic surfactant, optionally together with a solvent or oil, is made present in the composition to be melt-kneaded, the size of dispersed particles can be greatly reduced in the formed aqueous dispersion even if a resin having a very high molecular weight or a high melt viscosity is used.
