  • Process for producing acetic acid or methyl acetate and catalyst therefor
    Patent number: 5679837
    Abstract: The present invention relates to:(1) a novel catalyst which has a high catalytic activity, is useful in the production of acetic acid and/or methyl acetate from methanol, and is obtained through ion exchange of an anion of an anion exchanger with an anion of an Ru--Sn hetero-polynuclear compound;(2) a novel catalyst which has a high catalytic activity, is useful in the production of acetic acid and/or methyl acetate from methanol, and is obtained through ion exchange of a cation of a cation exchanger with a Ru complex and treatment with a Sn compound;(3) a process for producing acetic acid and/or methyl acetate from methanol through a one-stage reaction in a gas phase wherein the catalytic activity is maintained throughout the reaction; and(4) a process for producing acetic acid and/or methyl acetate in the presence of a highly active catalyst, for example, the catalyst specified in (1) or (2), at a high reaction rate.
    Type: Grant
    Filed: February 23, 1996
    Date of Patent: October 21, 1997
    Assignee: Daicel Chemical Industries, Ltd.
    Inventor: Sumio Shinoda
  • Ru-Sn hetero-polynuclear complex and process for producing acetic acid or methyl acetate by using the same
    Patent number: 5414110
    Abstract: The present invention relates to(1) a Ru-Sn hetero-polynuclear complex as a novel catalyst which has a high catalytic activity and is useful for producing acetic acid and/or methyl acetate from methanol, and(2) a process for producing acetic acid and/or methyl acetate through a one-stage reaction starting with methanol wherein a catalyst can be used at a high concentration and the catalytic activity is maintained throughout the reaction.
