Title: Purification of methacrylic acid
Inventor: IWASAKI KOZO
IPC: C07C51/00
Filed: 1985-03-14
Abstract: PURPOSE:To obtain methacrylic acid, easily, in high purity, by carrying out the catalytic oxidation of a 4C compound with an O2-containing gas in the presence of stream, and selectively removing the dibasic acid in the objective compound with a basic anion exchange resin. CONSTITUTION:Methacrylic acid is produced by the catalytic oxidation of isobutylene, tert-butanol, methacrolein or isobutylaldehyde with an O2-containing gas in the presence of steam. In the above process, the produced compound is treated with a basic anion exchange resin [e.g. strongly basic resin having an ion exchange group of formula I or II, weakly basic resin having N(CH3)2 or polyamine group, or medium basic resin having CONH(CH2)nN(CH3)2 group] preferably at 10-60 deg.C, especially at 25-40 deg.C to obtain the objective compound having high purity and essentially free from the dibasic acids such as maleic acid and citraconic acid, etc. which are characteristic impurities of the above reaction. The compound can be produced easily and economically from energy, apparatus and industrial points of view.

Title: Electrophotographic sensitive body
Inventor: MORIMITSU YOSHINORI
IPC: G03G5/05
Filed: 1988-03-02
Abstract: PURPOSE:To obtain an electrophotographic sensitive body having high spectral sensitivity in 700-1,000nm region and to improve long period stability thereof by incorporating a singlet oxygen quencher, particularly, a chelate compd. of a transition metal into an electrophotographic sensitive body. CONSTITUTION:A photoconductive layer contg. ZnO, an electrophilic compd., a binder resin, a cyanine dye, and a singlet oxygen quencher is formed on an electroconductive base body. Said electrophilic compd. is used as a spectral sensitizing additive. Said singlet oxygen quencher functions to transform a singlet oxygen generated in the system to triplet state, and to prevent deterioration due to oxidation of a cyanine dye. A chelate compd. of a transition metal is preferred as the single oxygen quencher to be added because of its higher effect for improving the stability, light resistance of an electrophotographic sensitive body, effect for increasing adsorption of long wavelength light, and superior compatibility with the dye, etc. Thus, high sensitivity for long wavelength light having 700-1,000nm wavelength is obtd., and the stability for light and head and long period preservability are obtd.

Abstract: PURPOSE: To efficiently separate U from U-contg. mudstone by converting finely pulverized U-contg. mudstone dissolved in acid into hydroxide with NH 3  and dissolving the hydroxide in hydrochloric acid followed by treatment with an anion exchange resin, elution with hydrochloric acid of a predetermined concn., pH adjustment, addition of EDTA and treatment with a cation exchange resin.  
     CONSTITUTION: Finely pulverized U-contg. mudstone is heat dissolved in acid or alkali carbonate, and hydroxide is precipitated with ammonia water dissolved in hydrochloric acid. After separating undissolved residue the soln. is treated with an anion exchange resin column, and Fe and U are eluted with 0.5N hydrochloric acid. This eluate is adjusted to pH 1.5W2.5 with NaOH, and EDTA is added to the eluate, which is then treated with a cation exchange resin column to allow U to be adsorbed on the resin. This U is eluted with 2N hydrochloric acid, and by adding ammonia water to the eluate U is precipitated. This precipitate is calcined to recover U as high purity U oxide in a high yeild.

Abstract: PURPOSE: To form dense, deep, and fine etching holes on the whole substrate uniformly and to improve the exfoliation resisting property of coating formed on said substrate, by carrying out electrolytic treatment of Al material by using the combination of alternating and direct current by switching the alternating and direct current alternately.  
     CONSTITUTION: Alternating current having current density of about 1W20A/dm 2  and direct current having current density of about 5W50A/dm 2 , are turned on switching alternately at the period of current trnasmission time of about 0.1W120 sec. and Al material is treated electrolytically. Ratio of the current density of the alternating and direct current and that of the current transmission time, are selected within the range of about 1:1W1:10 corresponding to the quality of the Al material. By the above treatment, dense, deep, and fine holes are formed extending over the whole substrate of the Al material and the surface of the substrate is roughened. Accordingly, exfoliation resisting property of coating is improved by its anchoring effect when the resin coating is formed on its surface.

Filed: 1986-03-07
Abstract: PURPOSE:To extract and transfer the following tritium to the other side of a diaphragm from a medium contg. tritium of one side of the diaphragm which is pure and has easily utilizable pressure by using the diaphragm wherein an electrically-conductive substance for hydrogen ion is sandwiched by hydrogen permeable metallic membrane electrodes are conducting current between both electrodes. CONSTITUTION:A diaphragm is formed by sandwiching both sides of a substance 1 such as ion exchange resin and beta''-alumina which is an electric charge carrier of hydrogen ion by means of metallic membranes 2, 3 (electrodes) such as Pd and Pt wherein hydrogen is selectively permeated and it is no permeable for the other substance. When conducting current between both electrodes, tritium <3>H contained in a medium 4 is dissociated and dissolved in the electrode 2, reaches the interface of the electrode 2 and a proton electric conducto4 1, is ionized and migrated in the electric conductor, reaches the electrode 3, and again becomes at atomic state. This tritium is permeated through the electrode, thereafter made into gaseous tritium, and discharged to 5. In such a way, low-partial pressure tritium contained in the medium is extracted as gaseous tritium which is pure and has easily utilizable pressure by utilizing the simple elecrochemical cell structure.

IPC: C23C14/32
Filed: 1979-04-23
Abstract: PURPOSE:To form metallized film of high purity in metallizing a substrate to be metallized with an ionized metallizing material, by installing a trap net, to which negative voltage is applied, between the substrate to be metallized and an ionization apparatus in order to catch the ionized impurities. CONSTITUTION:An evaporation source 2 and a substrate 3 to be metallized are arranged in an evacuated bell jar 1, and a trap net 10, to which negative voltage is applied, is placed between the evaporation source 2 and the substrate 3. Material to be evaporated such as Se is put into the evaporation source 2 and is evaporated by heating with a W wire 4, and is ionized with an electron beam generated from an electron beam generator 8. In that case, vapor of impurities contained in Se, for example Na, Ca, Fe, Cu etc. is also ionized, however major part of the impurity vapor is caught by the trap net 10. Hence the substrate plate 3 applied similarly with negative voltage is metallized with only Se ions to form Se film of high purity. This method permits to form metallizing film of high purity by the use of a metallizing material of low purity.
