摘要：

UV spectrophotometry of a Hammett indicator revealed that the acid strength of the Keggin-type heteropolyacids having W as addenda atoms increased as the valency of the central atom increased (Co < B < Si, Ge < P). The catalytic activity for the decomposition of isobutyl propionate in a homogeneous system was correlated well with the acid strength.
