    摘要: Silicon nitride of improved quality is obtained by using a liquid silicic acid or modified liquid silicic acid as a silicic substance and carbon in a powdered form, a precursor of carbon in a powdered form, or a precursor of carbon in the form of a solution as a carbonaceous substance, and thermally treating these raw materials in a non-oxidative atmosphere containing nitrogen. By this method, .alpha.-type silicon nitride can be easily obtained. Particularly, finely divided .alpha.-type silicon nitride suitable for use as the raw material for the production of high-strength sintered articles is also produced. .alpha.-type silicon nitride whiskers useful as a reinforcing material for ceramic and metallic articles is also obtained.

    摘要: Manufacture of orthomethylated phenol compounds by the reaction of phenol compounds having a hydrogen atom at the ortho position and methanol is accomplished advantageously by a method which effects the reaction by use of a catalyst comprising (A) iron oxide, (B) indium oxide, and (C) at least one member selected from the group consisting of chromium oxide and silicon oxide. According to this method, the reaction permits the orthomethylated phenol compound to be produced in high yields for a long time because of the catalyst's excellent activity-retaining property. Since the ortho-position selectivity and the utilization ratio of methanol are high and, consequently, the utilization efficiency of raw materials is high, the method of this invention produces the orthomethylated phenol compound with high efficiency from the phenol compounds.

    摘要: A persistent photoconductive element comprising an electroconductive support, a pigment layer formed on said support and composed mainly of a phthalocyanine pigment or Indanthrene Blue GCD and a polymer layer formed on said pigment layer and composed mainly of a polyvinyl carbazole, said polymer layer containing at least one member selected from the group consisting of aliphatic halogenated hydrocarbons, halogenated acyl compounds, halogenated keto compounds and hydrogen donor compounds. This element exhibits an improved photoconductive sensitivity and prolonged photoconductivity over the prior art, whereby it is highly useful in electrophotographic processes requiring persistent photoconductivity. Additives, such as plasticizer and binding agent, may be incorporated in the polymer and pigment layers to improve the flexibility and mechanical durability of the persistent photoconductive element.
