通过一系列滴定量热测定，求得了２９８．１５Ｋ时十二钨硅酸及其６ＤＭＦ、８ＤＭＳＯ加合物的标准生成焓，其数值分别为－（１３．１４±０．０１）×１０３ＫＪ·ｍｏｌ－１、－（１３．６１±０．０１）×１０３ＫＪ·ｍｏｌ－１及－（１３．８６±０．０１）×１０３ＫＪ·ｍｏｌ－１．
Through a series of titration calorimetry, the standard enthalpies of formation of dodecenyl tungstosilicic acid and their 6DMF and 8DMSO adducts at 298.15K were obtained and their values were - (13.14 ± 0.01) × 103KJ · mol -1, - (13.61 ± 0.01) × 103KJ · mol-1 and - (13.86 ± 0.01) × 103KJ · mol-1, respectively.
