  • Crystal polymorph of fluorene derivative and production method thereof
    Patent number: 8093434
    Abstract: A method of producing a crystal polymorph of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene, comprising the steps of reacting fluorenone and 2-phenoxyethanol in the presence of a heteropolyacid, initiating deposition of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene at lower than 50° C. from the resultant mixture to obtain a crude product of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene, dissolving the crude product in at least one solvent selected from the group consisting of aromatic hydrocarbon solvents, ketone solvents and ester solvents, and initiating deposition of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene at 50° C. or higher.
    Type: Grant

  • Process and composition for fixing black-and-white silver halide photographic materials
    Patent number: 5298373
    Abstract: Silver halide black-and-white photosensitive material is processed with a fixer which contains 0.5 to 2.0 mol/liter of a thiosulfate and 0.003 to 0.3 mol/liter of a meso-ionic compound, the moles of the meso-ionic compound divided by the moles of the thiosulfate being from 0.003 to 0.2. The fixer accelerates fixing speed, enabling rapid processing of photographic material.
