and Summary A copper‐silica catalyst was prepared by adding copper nitrate solution to sodium silicate. The precipitated copper‐silica catalyst was washed, dried, and heat‐treated at high temperatures. The effect of preparational variables upon catalyst activity and selectivity for the hydrogenation of soybean oil was investigated. The optimum conditions were precipitation at 25 to 55 C, drying the catalyst by freeze drying, and heat treatment at 500 C. The catalyst obtained under these conditions is more than three times as active as a commercial copper‐chromite catalyst.
