  • Patent number: 4780448
    Abstract: A catalyst containing copper and silica is prepared by a process in which an aqueous alkali metal silicate solution containing from 1 to 26% by weight of SiO.sub.2 is brought to a pH of from 0.5 to 2.0 with nitric acid, an aqueous copper nitrate solution containing from 5 to 15% by weight of Cu is added, after the addition of the nitric acid, so that a clear solution containing from 0.18 to 3.0 moles of Cu per mole of SiO.sub.2 is formed, the resulting solution is mixed with an aqueous alkali metal carbonate solution at from 40.degree. to 80.degree. C., the pH of the mixture being kept at from 7.5 to 8.5, and the precipitated material is separated off, dried, calcined by heating at from 250.degree. to 400.degree. C. and pressed in a conventional manner to give catalyst moldings. The catalyst thus obtained is used for the hydrogenation of dialkyl dicarboxylates to diols.

  • Patent number: 4093668
    Abstract: Butynediol is prepared by reacting acetylene and formaldehyde in contact with a heavy metal acetylide as catalyst, in the liquid phase by the Reppe method. Acetylene is fed upwardly through a suspension of the catalyst in formaldehyde at such a rate that it is virtually completely consumed and a liquid zone containing no catalyst is formed above the suspension.

  • Patent number: 4067914
    Abstract: In a process for the manufacture of butynediol by the reaction of formaldehyde and acetylene in aqueous solution, in which a catalyst is used which is produced by the action of acetylene and formaldehyde on copper (II) compounds, the catalyst becomes inactive when it is treated for a relatively long period with formaldehyde at elevated temperature in the absence of acetylene so that it must constantly remain in contact with acetylene-containing solution if its temperature is above 70.degree. C.
