Calculation of heats of vaporization of selected groups of organic compounds containing oxygen, sulphur or nitrogen by using saturated vapour pressure data

Transferable step potentials for amines, amides, acetates, and ketones

“…The primary amines exhibit mild hydrogen bonding, secondary amines exhibit weaker association, and tertiary amines do not associate. Experimental data are available over a wide range of temperatures for the primary amines from ethyl-to n-nonyl amine but are less extensive for secondary and tertiary amines [23].…”

Vapor pressure data of nicotine, anabasine and cotinine using differential scanning calorimetry

“…Table 5 shows publications with vapor pressure fitting equations derived by others from data from publications given in Table 4. Examination indicates that the first three equations in Table 5 (references [28][29][30]) are derived only from the data of Young and Nelson [25]. Here, it is worth mentioning that our evaluation of the Wagner equation constants presented in reference [30] indicate that the Wagner and modified Redlich-Kwong-Soave equation constants could have been switched at the time of publication.…”

In Table 5 the correct constants for the correlation of Basarova et al [30] are shown in accordance with our observation. The two equations from reference [31] are derived from the combined data of Young and Nelson [25], Gorbachev [26], and Norton et al [27].…”
