At Least One Carbocyclic Ring And Only Carbon And Hydrogen Atoms In Product Produced Patents (Class 204/158.14)
  • Patent number: 9944574
    Abstract: The invention discloses a continuous process for producing high-pure quadricyclane, in which “a reaction-rectification integral process” or “a reaction followed by rectification process” may be employed. The two processes both use a novel composite catalyst which is obtained by loading an organic photo-sensitizer on a solid photocatalyst, and the composite catalyst has a high activity and a good stability. In the reaction-rectification integral process, the composite catalyst is used by being blended with rectification fillers or covering the rectification fillers, so as to achieve the integration of the reaction and the rectification. In the reaction followed by rectification process, the composite catalyst and the rectification fillers are placed separately from each other. The two processes achieve a relatively short residence time of reactants, produce highly-pure quadricyclane, and reduce the formation of cokes.

  • Publication number: 20140360860
    Abstract: The present invention provides a method for manufacturing a liquid crystal display device, which hardly causes alignment defects in the case of forming a horizontal alignment film by employing a photo-alignment treatment. The method for manufacturing a liquid crystal display device of the present invention includes a step of forming a horizontal alignment film by carrying out a photo-alignment treatment of irradiating a photo-alignment film material applied to at least one substrate of a pair of substrates with light, wherein the photo-alignment treatment is a treatment for irradiating the same region with light two or more times from a slanting direction with respect to a surface of the at least one substrate of the pair of substrates, and at least two of lights applied two or more times in the photo-alignment treatment are polarized lights applied from directions mutually different at 90° or greater.

  • Publication number: 20120181163
    Abstract: A method of transferring electrons with a light energy conversion material is described. The material includes a silica porous material having silicon atoms chemically bonded with an organic group that is an electron donor in a skeleton thereof, and an electron acceptor disposed in at least one portion among a pore, the skeleton and the outer circumference of the porous material. The method includes absorbing light energy by the organic group and transferring electrons excited by the light energy to the electron acceptor.

  • Patent number: 7655115
    Abstract: An apparatus and method provide a solute-solvent solution that allows the solute to become photo-protonated by the solvent on absorption of ultraviolet light. The solute is 1,2,3,4,5,6,7,8-octamethylanthracene (OMA). The solvent is 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). The protonated form of the solute absorbs visible light to change the coloration of the solution from a substantially clear state to a colored state.

  • Patent number: 7122642
    Abstract: A method to prepare new or unexpected polymorphs of materials which have not been observed, or to obtain a known polymorph under different conditions than those in which it is usually made, by using a laser to cause nucleation and crystal growth to occur in a supersaturated solution in such a way as to obtain a crystal structure which would not normally appear without the use of the laser.
