| PURPOSE: To efficiently decompose halogenated hydrocarbon in air by bringing the halogenated hydrocarbon into contact with a mixture soln. of 1,3-dimethyl-2- imidazolidinone and caustic alkali at specified temp. CONSTITUTION: Halogenated hydrocarbon existing in air is brought into contact with a decomposer of halogenated hydrocarbon comprising a mixture soln. of 1, 3-dimethyl-2-imidazolidinone (DMI) and caustic alkali at temp. from 50°C to 150°C. The proportion of DMI and caustic alkali to be used can be freely selected. Such a state may be allowed that the caustic alkali is completely dissolved in DMI or an excess amt. of caustic alkali exists as undissolved in DMI. Thereby, halogenated hydrocarbon in air by about 1000-500ppm can be almost completely decomposed at high efficiency. COPYRIGHT: (C)1992,JPO&Japio | ||||||

| 186 | Decomposition combustion disposal method for organic chlorine compound | JP308990 | 1990-01-09 | JPH03289973A | 1991-12-19 | IMAMURA SEIICHIRO; TERUI SADAO; SANO KUNIO; NISHIKAWA KAZUYOSHI; INOUE AKIRA |
| PURPOSE: To perform combustion disposal of an organic chlorine compound at a low temperature with high efficiency without generating chlorine gas having high toxicity by converting chlorine in an organic chlorine compound into HC1 through contact of the organic chlorine compound with a compound oxide catalyst selected from a specified two-or three-component oxide and burning. CONSTITUTION: At least one kind of a compound oxide catalyst selected from a two-dimensional composite oxide formed of titanium - silicon, a, two- component oxide formed of titanium - zirconium, and a three-component oxide formed of titanium - silicon - zirconium is used. By using the catalyst, chlorine in the organic chlorine compound can be converted into HC1 at a low temperature with high efficiency, and besides since carbide is not deposited on a catalyst surface, catalyst activity is continued for a long time. When other catalyst, e.g. a transition metal catalyst oxide, is used, chlorine gas having high toxicity is generated from the organic chlorine compound. When other solid catalyst, e.g. silica - alumina, mordenite, and zeolite, usually used is used, the coefficient of decomposition is lowered and catalyst activity is reduced.

| PURPOSE:In producing methane chloride by photochlorination reaction of chlorinated methanes, to obtain the titled substances efficiently while washing a film of ferrous chloride continuously or intermittently, by setting circumferentially a wiper at the outside of a protecting tube of a light source. CONSTITUTION:The high-pressure mercury vapor lamp 1 protected by the protecting tube 2 of a light source made of hard glass is inserted into the photochlorination reactor 3, cooling water is passed through the inside of the protecting tube 2 of a light source and the chlorination reaction is carried out. The ring-shaped wiper 4 having a size not to inhibit the reaction is circumferentially set at the outside of the protecting tube 2 of a light source and the wiper 4 is connected to the movable block 5 supported by the stand 5 so that it can be vertically slid. The material of the wiper 4 has no influence on both the raw material and the reaction product and is not affected by them, does not damage the surface of the protecting tube, and polyethylene, nylon, etc. can be used as the material. The surface of the protecting tube 2 is washed by the wiper 4, and reduction in reaction ratio and reduction in ability caused by operation suspension for washing can be avoided. | ||||||

| PURPOSE: To obtain a chloromethane with a high reaction rate of chlorine and increased selectivity for the chloromethane, by carrying out the partial chlorination of methane or the photochlorination of chlorine in the vapor phase in the presence of the liquid phase. CONSTITUTION: Methane or partially chlorinated methane is reacted with chlorine in a photochlorinating ractor to give a chloromethane. In the process, the reaction is carried out in the presence of the liquid phase. The condensate of a reaction mixture from the photochlorinating reactor is partially circulated for use advantageously as the coexisting liquid phase. More preferably, the uncondensed gas containing HCl formed as a by-product as a principal component from the reactor is circulated through the reactor for use, and the gas-liquid contact efficiency in the reactor is increased to remove the heat of reaction more efficiently. The amount of the liquid phase present in the reactor is preferably in the range of 0.02W0.20mol based on 1mol total amount of the gaseous and liquid phases. COPYRIGHT: (C)1982,JPO&Japio | ||||||

| PURPOSE: To obtain the titled compound very favorably without pressurizing, by reacting CH 3Cl with Cl under such a pressure as to keep the CHCl 3 in the liquid phase at an advantageous reaction rate, and by rectifying and separating the by- product HCl or unreacted CH 3Cl under a slowly decreased pressure. CONSTITUTION: CH 3Cl is reacted with Cl in the presence of a radical initiator under such a high pressure as to keep the CH 3Cl in the liquid phase at an advantageous successive chlorination rate of K 1/K 2/K 3=1:38:0.076 with a very small amount of CCl 4 formed without danger of explosion to give HCl, the unreacted CH 3Cl and chlorinated methane. HCl is separated by rectifying the resulting product at a pressure lower than that in the reaction without any additional pressurizing means, and the unreacted CH 3Cl is then separated by rectifying at a lower pressure without any additional pressurizing means to separate the chlorinated methane in the decreasing order of the boiling point and to simplify the device.

| PURPOSE: To recover a halogen compound adsorbed on active carbon in a simple process with slight decomposition of the compound without corrosion problems of devices, by using low-temperature steam in vacuo rather than high-temperature one under normal pressure. CONSTITUTION: A halogen compound, e.g. methylene chloride, chloroform, or trichloroethylene, adsorbed on active carbon is desorbed by treating with water at 10W100°C or an aqueous solution containing a stabilizer of a halogen compound, e.g. an ether or nitroparaffin, at 10W100°C in vacuo, and recovered. For example, an active carbon adsorption tank is charged with water or the solution at 10W100°C, and evacuated to distill away the compound as a vapor, which is recovered.

| PURPOSE: To prepare industrially useful CCl 4 and CCl 3CCl 3, easily and at low cost, by chlorinating a substance containing 1-2C chlorinated hydrocarbons, which is industrial waste, in an anhydrous condition and in the presence of free-radical initiators. CONSTITUTION: A mixture containing 1-2C chlorinated hydrocarbons, which is discharged in the process of vinyl chloride monomer production, trichloroethylene, prechloroethylene production, etc., is dehydrated by distillation, etc. Subsequently, said mixture is brought into contact with chlorine or a chlorine-containing gas in the presence of a free-radical initiator (preferably azobisnitriles) under the pressure sufficiently high to keep said mixture liquid, to convert 1C compound into CCl 4 and 2C compound into CCl 3CCl 3 (solid), which are separated and recovered. Reaction temperature is 30W150°C, preferably 40W120°C. COPYRIGHT: (C)1979,JPO&Japio | ||||||

| PURPOSE: To prepare hexachloroethane at low cost in simple process, by the chlorintion of tetrachloroethylene using azobisnitriles as a catalyst. CONSTITUTION: In the preparation of hexachloroethane by chlorinating tetrachloroethylene, the chlorination reaction is carried out above 50W60°C, adding 0.001W 1.0 wt.% (preferably 0.01W0.1 wt.%), based on the chlorination solvent, of azobisnitriles of formula (R 1WR 4 are alkyl or cycloalkyl; pref. azobisisobutyro- nitrile ) as a catalyst.
