    摘要: A process for purifying crude p-aminophenol which contains 4,4'-diaminodiphenyl ether and other impurities, which process comprising adding an alkali metal compound to the crude p-aminophenol in an aqueous medium in an atmosphere of an inert gas and, if necessary, in the presence of a reducing agent to give an aqueous solution of an alkali metal salt of p-aminophenol, and contacting the aqueous solution with an inert organic solvent immiscible with water to permit 4,4'-diaminodiphenyl ether and other impurities to be separated by extraction in the solvent.

    摘要: A process for forming a deposited film comprises the steps of:(a) arranging previously a substrate for formation of a deposited film in a film forming space;(b) forming a deposited film on said substrate by introducing an activated species (A) formed by decomposition of a compound (SX) containing silicon and a halogen and an activated species (B) formed from a chemical substance (B) for film formation which is chemically mutually reactive with said activated species (A) separately from each other into said film forming space to effect chemical reaction therebetween; and(c) exposing the deposited film growth surface to a gaseous substance (E) having etching action on the deposited film to be formed during the film forming step (b) to apply etching action on the deposited film growth surface, thereby effecting preferentially crystal growth in a specific face direction.
