실험 절차

As described in detail in copending application Ser. No. 924,212, filed July 12, 1978, (FDN-1113), the catalyst of the invention will produce high quality butanediol by a process involving a two-stage catalytic hydrogenation of a butynediol solution containing formaldehyde. During the first stage of the process, or low pressure, low temperature stage, a butanediol product having a much lower carbonyl number is obtained. The carbonyl number is the conventional measure of the undesired aldehyde and acetal content including residual formaldehyde. In the second or finishing stage, which is carried out at higher pressures and/or temperatures than the first stage, much less 2-methyl-1,4-butanediol byproduct (methylbutanediol) is produced concurrently with butanediol.
