Title:
CATALYST AND METHOD FOR PREPARING ISOPENTYL DIOL
Document Type and Number:
WIPO Patent Application WO/2020/192477
Kind Code:
A1
Abstract:
The present invention provides a catalyst and method for preparing isopentyl diol, the catalyst being a supported catalyst; said supported catalyst consists of active metal and metal-organic framework materials; the method uses 3-methyl-3-butene-1-ol and water as raw materials, and isopentyl diol is prepared under the effect of the described catalyst. The beneficial effects of the present invention are: the present invention uses a supported catalyst to prepare isopentyl diol, the amount of catalyst used is small, the yield is high and product purity is high, and the reaction is completed within 6 hours, at high reaction efficiency, which is advantageous to industrial production. The method has a mild reaction temperature, the reaction temperature being 50-90°C; the reaction is carried out at atmospheric pressure, and the requirements of reaction equipment for industrial production are reduced; at the same time, the safety of the process is improved, the catalyst can be applied stably, the amounts of waste water, gas, and solids are small, the process is simple, there is no corrosion to equipment, and costs are low, such that the invention is suitable for industrial production.
