실험 절차

The initial unimpregnated chi-rho alumina (Kaiser KA-300) had a surface area of 350 m2 /gram. On roasting, it was converted to a mixture of eta and pseudogamma phase aluminas. As shown in Table I, this alumina support for the catalyst of this invention is far less soluble in the liquid reaction medium than are the kieselguhr or magnesium silicate supports. Furthermore, it was found that the aluminasupported catalyst converted formaldehyde and acetylene to butynediol at a rate similar to that obtained with the other two catalysts but give a ratio of propargyl alcohol to butynediol three times that obtained with the magnesium silicate supported catalyst or kieselguhr supported catalyst.
