  • Publication number: 20230406791
    Abstract: Provided is a method for preparing a diol. In the method, a saccharide and hydrogen as raw materials are contacted with a catalyst in water to prepare the diol. The employed catalyst is a composite catalyst comprised of a main catalyst and a cocatalyst, wherein the main catalyst is a water-insoluble acid-resistant alloy; and the cocatalyst is a soluble tungstate and/or soluble tungsten compound. The method uses an acid-resistant, inexpensive and stable alloy needless of a support as a main catalyst, and can guarantee a high yield of the diol in the case where the production cost is relatively low.

  • Patent number: 10836696
    Abstract: The present invention provides a method for increasing the UV transmittance of ethylene glycol. The method uses an ethylene glycol solution and hydrogen as raw materials, and uses an alloy catalyst comprising nickel, one or more rare-earth elements, tin, and aluminum, the contents thereof in parts by weight being 10-90, 1-5, 1-60, and 5-9, respectively. The method of the present invention uses an inexpensive, stable-in-aqueous-phase, carrier-free alloy as a catalyst, and continuously adds hydrogen to reduce unsaturated impurities in ethylene glycol. In application of the method of the present invention in continuous industrial-scale production, the use of this type of alloy catalyst could be especially significant for the achievement of long-term system stability and control of production costs.
