Abstract
Mercuric chloride catalysts are used to catalyze acetylene hydration for acetaldehyde production with high activity, but high toxicity limits its practical application. Here we present a phosphorus and sulfur ligands-complexed copper catalyst assessed for acetylene hydration. The optimum catalyst gave more than 94.0% acetylene conversion and 88.4% aldehyde selectivity at 10 h. After running for 20 h, the catalyst showed high stability. The conversion to acetylene remained stable at over 93.3% and the selectivity of aldehyde decreased from 92.2% to 79.7%. The accession of phosphorus and sulfur could be highly vigorous for the acetylene hydration reaction. All the catalysts were characterized by XRD, XPS, ICP, TPR, TEM, FT-IR and BET technologies. The results indicate that the selectivity of the catalysts is mainly improved by the P fragment of the ligands, and the S fragment of the ligands could restrain the loss of copper species to improve the stability of the catalysts.
