摘要

Butane-1,4-diol (BAD) production is estimated to be several million tons per year, and the demand is constantly increasing. On an industrial scale, BAD is produced by the catalytic hydrogenation of 2-butyne-1,4-diol (BYD) at a temperature of (403–433 K) and a pressure range of 1.5 × 107–3 × 107 Pa. However, the reaction at these conditions produces a mixture of difficult products to separate. Therefore, there is still a need to develop an alternative catalyst that is active at mild conditions. Herein, we have revealed the catalytic performance of Pd nanoparticles immobilized on polymeric resin with terminal -NH₂ functional groups in the liquid phase flow butane-1,4-diol synthesis under 3 × 105 Pa and 318 K. 2.16 wt% Pd/Polym with an average NP size of 3 nm leads to the formation of 100% butane-1,4-diol while keeping 100% 2-butyne-1,4-diol conversion at mild conditions, exceeding most of the reported results of butane-1,4-diol synthesis.
