| 摘要 |
A de-alkylation process which comprises contacting a t-alkylether-alkanol, e.g. 4-t-butylether-n-butan-1-ol, with an acidic solid mixed oxide, e.g. silica-alumina, catalyst which results in the formation of alkanediols, e.g. 1,4-butanediol, in the substantial absence of undesirable side reactions, e.g. the formation of tetrahydrofuran. The resulting alkanediols are useful in the preparation of polyesters, e.g. polybutylene terephthalates.
