Abstract
The copper catalyst and reaction process of a kind of volatile corrosion inhibitor film isopropanol acetone are the invention provides a kind of preparation method of the copper-based composite photocatalyst of titanium dichloride load and its oxidation of photocatalysis part isopropyl alcohol prepares acetone under gas phase condition technique.Using titanium dioxide as carrier（Mixed phase containing Detitanium-ore-type or anatase and a small amount of rutile）, soluble copper salt is copper species（Metallic copper, cupric oxide, cuprous oxide）Presoma, sodium borohydride is reducing agent, prepares the Nanometer Copper composite catalyst of titanium dichloride load, the catalyst under ultraviolet light, can in oxygen-containing atmosphere by isopropanol gaseous partial oxidation prepare acetone product.The characteristics of prepared catalyst has that stability is good, high conversion rate, and principal product is selectively high.
