Abstract: Production of very pure butanediol-1,4 by separating in column 1 crude butanediol into a fraction A containing butanediol and lower boiling components and a fraction B containing higher boiling components, separating fraction A in column 2 into an overhead and a bottoms product consisting of very pure butanediol and separating fraction B in column 3 into butanediol of lower purity and components of higher boiling point.

Abstract: A process for the preparation of saturated alcohols by catalytic hydrogenation of acetylenic alcohols at a temperature of from 50 DEG to 200 DEG C. and under a pressure of from 30 to 320 bar, wherein use is made of a catalyst containing from 20 to 85% of nickel oxide, from 0 to 30% w/w of copper oxide, from 1 to 30% w/w of zirconium dioxide, from 1 to 30% w/w of silicon dioxide and from 1 to 30% w/w of aluminum oxide, by weight of the oxidic, unreduced catalyst.

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.

Abstract: Production of very pure butanediol -1,4 by distillation of the crude product, obtained by hydrogenation of butine -2-diol-1,4 in aq. soln., with removal of water and cpds. boiling below 120 degrees C. Process is improved by subjecting the product to a subsequent three-stage fractional distillation. In the first column, fraction A contg. 60-90 wt.% of total butanediol and components boiling below the b.pt. of butanediol and fraction B contg. 40-10 wt.% of total butanediol and higher boiling components are obtained. In the second column, fraction A is separated into a head fraction contg. low-boiling components and a still residue being high purity butanediol. In the third column, fraction B is separated into high-boiling components and butanediol, which is pref. returned to the first distillation stage. Prodn. of polyesters or polyurethanes. High-purity, water-free butanediol is obtained from the second column; less pure butanediol obtained from the third column, can be recycled or used for the prodn. of THF or butyrolactone.
