    摘要： A process by which iodine compounds contained in crude acetic anhydride or a mixture of crude acetic anhydride and crude acetic acid can be converted into methyl iodide having a low boiling point and which can be separated by distillation and efficiently removed by the combination of the conversion step with the heat treatment step and distillation step. The process includes the steps of heat-treating the crude acetic anhydride or the mixture of crude acetic anhydride and crude acetic acid in the presence of methanol and/or methyl acetate in a treatment tank and distilling the heat-treated crude acetic anhydride or the heat-treated mixture of crude acetic anhydride and crude acetic acid, in the presence of an alkali metal salt and/or an alkaline earth metal salt if necessary.

    摘要： By employing a process for the preparation of acetic acid which comprises carbonylating methanol with carbon monoxide in a first reactor in the presence of a reaction fluid comprising a rhodium catalyst, methyl iodide, an iodide salt, methyl acetate and water, while continuously withdrawing the reaction fluid from the first reactor and introducing it into a flash zone to separate it into an evaporated part and an unevaporated part, characterized in that second reactor is provided between the first reactor and the flash zone and methanol is carbonylated with the carbon monoxide contained in the reaction fluid in a state in which it is dissolved therein in the second reactor with a residence time of 7 to 60 seconds at 150.degree. to 220.degree. C., the carbon monoxide contained in the reaction fluid withdrawn from the first reactor in a state in which it is dissolved therein can be converted into acetic acid in the second reactor through the same carbonylation as that occurring in the first reactor, which enables effective use and high recovery of carbon monoxide.

    摘要： A coating composition which is excellent in water resistance, weatherability and durability and can maintain its appearance for a prolonged period of time can be provided. A coating composition comprising a coating component and a photocatalyst containing calcium phosphate and titanium oxide is disclosed. As the photocatalyst, use is made of titanium oxide particles partially covered thereon with calcium phosphate, or porous body coated thereon with a film of titanium oxide, the film of titanium oxide being further covered partially thereon with calcium phosphate. The crystal form of titanium oxide is preferably anatase. The organic coating includes vinyl-type synthetic resin emulsions, and the inorganic coating is e.g. a solution containing a metal alkoxide for forming a film by a sol-gel method.
