以碳纳米管（CNTs）和炭黑（CB）两种不同的碳载体制备了Ru/CNTs（CNTs=carbon nanotubes）和Ru/CB（CB=Vulcan XC-72）两种负载型催化剂，并对其进行了表征。几种羰基化合物分别与乙二醇、1，2-丙二醇、1，3-丙二醇、1，2-二甲基乙二醇和2，2-二甲基丙二醇的缩合反应。结果表明，在这两种催化剂的催化下，各种醛、酮都能成功地转化为相应的缩醛、缩酮。催化剂循环使用5次后，催化剂活性无明显下降。
Two kinds of supported catalysts of Ru/CNTs (CNTs=carbon nanotubes) and Ru/CB (CB=Vulcan XC‐72) were prepared with the two different carbon carrier of CNTs and CB and were well characterized. The condensation reaction of several carbonyl compounds with different diols including ethanediol, 1,2‐propandiol, 1,3‐propandiol, 1,2‐dimethylethanediol and 2,2‐ dimethylpropandiol, respectively. It was found that various aldehydes and ketones were successfully transformed to the corresponding acetals and ketals with the catalysis of the two catalysts. Recyclability tests revealed that there was no obvious decreasing of the catalytic activities after 5 runs of the catalysts.
