摘要： The present invention aims at provision of an organic composite galvanized steel sheet having its characteristics such as corrosion resistance and workability improved. Thus, the present invention provides an organic composite galvanized steel sheet that is formed by sequentially depositing on a surface of a steel sheet a galvanization layer, a zinc phosphate layer containing Mg, and an organic layer, and is characterized in that a value of Mg/P (weight ratio) in the zinc phosphate layer is 0.15 or larger and an amount of Mg contained in the zinc phosphate layer is 20 mg/m2 or more. Preferably, the zinc phosphate layer contains one or two or more of Ni, Mn, Co, Fe, Cu, Al, and Ca. In one preferred embodiment, the organic layer is formed as a composite layer containing an organic resin and one or two kinds or more of powder or colloid selected from SiO2, Al2O3, MgO, Fe2O3, Fe3O4, ZrO2, TiO2, and SnO2.

摘要： A zinc-plated steel sheet with an ageing resistance is produced from an Al-killed steel by hot dip type, continuous zinc plating including recrystallization and annealing, where after recrystallization and grain growth, the steel sheet is quenched at a cooling rate of 30.degree..about.250.degree. C/sec from 720.degree..about.600.degree. C. to 310.degree..about.200.degree. C.; after keeping the steel sheet at the same temperature for 0 to 15 seconds, the steel sheet is reheated to a molten zinc bath temperature; then the steel sheet is dipped into the molten zinc bath for zinc-plating; and then the steel sheet is cooled at a cooling rate of 250 to 5.degree. C./sec from that temperature to 350.degree. C.; and then the steel sheet is cooled at a specific average cooling rate in a temperature region of 350.degree. C. to 300.degree. C. and at a specific average cooling rate in a temperature region of from 300.degree. C. to 285.degree..about.220.degree. C.

摘要： An improved method for the preparation of a naphthalene dicarboxylic acid by liquid-phase catalytic oxidation of a diisopropylnaphthalene in a lower fatty acid-based solvent is disclosed wherein a catalyst system comprising bromine and the heavy metals cerium, cobalt, and manganese is used. The cerium compound used as a cerium source for the catalyst can be recovered from crystals of the naphthalene dicarboxylic acid product by dissolving the crystals in an alkali solution and separating the cerium compound as insolubles from the solution.
