    摘要: A process for preparing a metallized polyimide film, comprising the steps of: forming a solidified film containing 100 parts by weight of an aromatic polyamic acid in the form of a solution obtained by polymerizing approximately equal moles of an aromatic tetracarboxylic acid component and an aromatic diamine component and 5 to 150 parts by weight of an organic polar solvent; applying a surface treatment solution containing a heat-resistant surface treating agent to the surface of the solidified film; heating the solidified film to a high temperature to imidize the polyamic acid, while drying the film to prepare a polyimide film; forming a thin metal vapor-deposited layer by a vapor deposition of a metal on the treated surface of the polyimide film with the heat-resistant surface treatment agent; and applying metal plating onto the metal vapor deposited layer to form a metal plated layer thereon.

    摘要: An alkyl nitrite is produced with high efficiency by bringing a nitrogen monoxide gas into contact with an aqueous solution of an alkyl alcohol and nitric acid in a reactor 2, which aqueous solution may be a liquid fraction generated in an alkyl nitrite-production process in which an alkyl alcohol is reacted with nitrogen monoxide and oxygen in a reaction column 1.
