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.

Claim (Index 6):
The method as claimed in  claim 1 , characterized in that the method further comprises the addition of ethylene glycol solution and metal alloy catalyst at any time; the amount added of the metal alloy catalyst is: 0.01-5 kg of metal alloy catalyst added per 1000 kg of ethylene glycol fed.
