Volumes and heat capacities of binary liquid mixtures of water—sulfolane and water—hexamethylphosphotriamide

Recommended vapor pressures for thiophene, sulfolane, and dimethyl sulfoxide

“…(5) in the temperature range studied. The deviations are systematically positive, except those of the data by Castagnolo et al [28], which might be attributed to a higher water content of sulfolane samples used in the previous studies [29][30][31]. No information about the water content is given in these studies.…”

“…5. The literature data [28][29][30][31] and recommended values by Zábranský et al [27] deviate by 1-2% from Eq. (5) in the temperature range studied.…”

“…The heat capacities of crystalline dimethyl sulfoxide were taken from [25] and used in the temperature range from 200 to 250 K in the SimCor method. For sulfolane, the critical review from 2001 [27] contains four sources and the recommendation is based on data by Castagnolo et al [28] and Steele et al [29]. The uncertainty assigned by Zábranský et al [27] is 1%.…”

“…No information about the water content is given in these studies. The water content w(H 2 O) of the sample used in [28] was less than 7 × 10 −5 . For the SimCor method, the liquid heat capacities obtained in this work were used in the temperature range from 304 to 355 K.…”

Liquid heat capacity of aqueous sulfolane+2-amino-2-methyl-1-propanol solutions

“…The heat capacities of sulfolane were measured for temperatures ranging from 303.15 to 353.15 K. The measured C p of sulfolane along with the literature values (Castagnolo et al, 1981;Steele et al, 1997) is presented in Table 1. As can be seen in Fig.…”
