  • Patent number: 10392334
    Abstract: A method and a system for inexpensively producing a corresponding target ketone and/or alcohol by decomposing hydroperoxide rapidly and with high selectivity using an aqueous alkaline solution and by recovering and recycling alkali. The method includes neutralizing at least a part of a carboxylic acid in the oxidation reaction solution by contacting the oxidation reaction solution with a first alkaline solution including a carbonate of an alkali metal, and separating the reaction mixture into a first oil phase and a first water phase; decomposing the hydroperoxide and the ester compound in the first oil phase by contacting the first oil phase with a second alkaline solution having a higher pH value than the first alkaline solution, and separating the reaction mixture into a second oil phase and a second water phase; and recovering the carbonate of an alkali metal from the first water phase and recycling the carbonate of an alkali metal to the first alkaline solution.

  • Patent number: 8796398
    Abstract: There are provided a composition for forming a superfine pattern and a method employing the same for forming a superfine pattern. The composition enables to simply produce a superfine pattern with high mass productivity. The composition comprises perhydropolysilazane (I), silicon-containing polymer (II) having a hydrocarbon group, and a solvent. The mixture of those polymers contains silicon-hydrogen bonds and silicon-hydrocarbon group bonds in such amounts that the number of the silicon-hydrocarbon group bonds is in a ratio of 1 to 44% based on the total number of the silicon-hydrogen bonds and the silicon-hydrocarbon group bonds. The composition is applied on a resist pattern to form a spacer formed of the composition on the side wall of the ridges in the pattern, and then the spacer or a resin layer disposed around the spacer is used as a mask to form a superfine pattern.

  • Publication number: 20130184494
    Abstract: According to the first embodiment of the present invention, an oxide of a hydrocarbon compound can be produced with high yield and high productivity by oxidizing the hydrocarbon compound with molecular oxygen in the co-presence of an N-hydroxy compound, such as methyl ethyl ketone or N-hydroxysuccinimide, and a phosphate ester, such as dibutyl phosphate. According to another embodiment of the present invention, an oxide of a hydrocarbon compound can be produced with high yield by using an oxidation catalyst that comprises an oxime compound, such as methyl ethyl ketone. According to another embodiment of the present invention, an alcohol and/or a ketone can be produced with high yield by oxidizing the hydrocarbon compound at a temperature of 160° C. or less, and by decomposing the resulting hydroperoxide, for example, in a unit having an inner surface formed by a material from which no transition metal ion is generated.
