Hydrogenation of 2-butyne-1,4-diol (B 3 D) using 1% Pt/CaCO 3 catalyst was carried out to give 2-butene-1,4-diol (B 2 D) or butane-1,4-diol (B 1 D) selectively or a mixture of two diols eliminating the formation of acetal, aldehyde, and alcohols as side products. In presence of ammonia, nearly compl
## Abstract Polyesters of butyneβ1,4βdiol (ByD) and aliphatic dicarboxylic acids (ADAs) were prepared in three different ways. Method I is based on the transesterification of ByD with the dimethyl esters of ADAs in bulk. Although catalyst and temperature were varied, only oligomers were obtained, b
