More Information
Summary:The invention provides a condensation reductive alkylation catalyst and preparation method and use thereof. The catalyst pertains to copper-based catalyst, and is prepared by coprecipitation method with acid or salt thereof as precipitator. The preparation method is energy saving and environment friendly for including no impurity natrium, which avoids environmental protection problem existing in catalysis preparation technology with traditional precipitation method and reduces washing water use. The specific surface area of the catalyst is 30.0 to 75.0m /g and pore volume 0.08 to 0.15ml/g. The catalyst can be used in condensation technology of RT Base and aliphatic ketone to inhibit an unnecessary side reaction in production of anti-aging agent 4010NA and 4020, especially to a reaction of aliphatic ketone alkylation regent hydrogenated to corresponding mellow.
