Title: Separation of leucine
Inventor: OTANI MASARU
IPC: C07C227/00
Filed: 1987-01-07
Abstract: PURPOSE:To obtain leucine simply and at low cost, by extracting an amino acid mixture containing leucine and isoleucine with a hydrophobic amino acid as a solvent and separating leucine. CONSTITUTION:Leucine is separated from an amino acid mixture containing at least leucine and isoleucine. In the operation, a solvent (saturated with water) such as 3-4C alcohol, etc., to be separated from water is sent under pressure against centrifugal force to an aqueous solution of the amino acid mixture kept by the centrifugal force and the aimed substance is extracted. The pH of the solution is 1-3 to raise solubility of the amino acid and an inorganic acid such as hydrochloric acid, sulfuric acid, etc., may be added. The content of isoleucine in the amino acid extracted in the organic solvent is <=2%.

The residual gas contg. H 2 S, SO 2 , COS, CS 2  is led to a Bebbon unit 4, where it is reduced in the presence of Co/Mo catalyst, so that the S cpds. are converted to H 2 S. The H 2 S-contg. gas is oxidized by passing it through a strettford unit constituted of a cooling and absorption unit 6, an oxidation unit 7, and a reslurry unit 8. After separation of S from the soln. having been used for the oxidation of the gas, supernatant cycle soln. is drawn off and delivered to a waste soln.-treating unit 9, where it is adjusted to a pH not higher than 3, then oxidized and decomposed by blowing air into it. The SO 2 -contg. air thus formed is circulated to the Claus process or the reduction process.

Abstract: PURPOSE:To maintain high-reliability gas detection ability for a long period by simple constitution by providing a pressure reduction chamber and a hydraulic pressure generation chamber in a united cylinder and sending sample oil to the cylinder. CONSTITUTION:The sample oil from a transformer 19 to the in-oil gas detecting device 1 is sampled. At this time, when valves 21, 24, and 25 are turned on and an oil pump 9 is rotated forward, the sample oil from the transformer 19 enters the pressure reduction chamber 3 through a valve 18, a strainer 17, and the valve 21 and further enters the hydraulic pressure generation chamber 4 through a valve 20. Then the pump 9 is rotated forward continuously to press a piston 6 to an outside air side and the piston 6 stops abutting on the end part of the cylinder 2. Then when the valves 20, 23, and 24 are turned on and the pump 9 is rotated forward, pressure oil is supplied continuously into the generation chamber 4, the piston 6 moves to the outside air side, and a piston 5 also moves to the outside air side accordingly. Consequently, the pressure in the pressure reduction chamber 3 drops to produce a vacuum and gaseous materials in the sample oil are separated to move up and stay at the upper part of the pressure reduction chamber 3.

Abstract: PURPOSE:To allow easy fine pattern formation in low vacuum or atmospheric air by applying a voltage between a needle and a substrate under the condition that the fine-tip conductive needle is brought to the distance which allows tunnel current to flow between needle and the substrate at a desired part on the substrate. CONSTITUTION:When a substrate 11 is placed in atmospheric air or in low vacuum, contamination 12 floating around the substrate is adsorved and accumulated. Then, when a needle 13 is brought closed to the surface of the substrate 11 and a voltage 14 is applied between the substrate 11 and the needle 13, a local electric field 15 is formed. Since the contamination 12 in the local electric field 15 receives energy from the field 15, when the needle 13 is scanned on the substrate, the fine pattern 12 of a contamination film is formed on the substrate 11. Thus, when the pattern is used as the mask for etching, etc., a fine pattern is easily formed.
