    摘要: The present invention provides a novel fluorination catalyst that has high stability at high temperatures, is easily regenerated and is superior in catalytic activity and selectivity and a method for the preparation of the fluorination catalyst. The present invention also provides a method for the preparation of a novel fluorinated compound, and particularly, 1,1,1,3,3-pentafluoropropane (HFC-245fa), by using the catalyst. The fluorination catalyst of the present invention is obtained by treating a metal salt containing a chromium salt such as chromium oxide with chlorine gas and/or oxygen gas. Examples of the metal salt may include, besides a chromium salt, one or more catalytically active metal salts selected from magnesium salts, aluminum salts, zinc salts, sodium salts, nickel salts, iron salts, cobalt salts, vanadium salts, manganese salts and copper salts.

    摘要: A plastic sheet includes a substrate having a surface formed with a plurality of embossed recess portions proximate to each other. Each of the embossed recess portions is confined by a flat bottom wall and a side wall that extends from the flat bottom wall to the surface. The plastic sheet has physical properties, such as improved breaking strength, stretching strength, and tearing strength.
