A note about Dr. K.C. Chaudhuri

High-pressure (up to 140MPa) density and derivative properties of some (pentyl-, hexyl-, and heptyl-) amines between (293.15 and 353.15)K

“…Our data have been compared with some literature data at atmospheric pressure: references [4][5][6][7] for pentylamine, [4][5][6][7][8] for hexylamine, and [5][6][7] for heptylamine at exactly the same temperatures than in this work. Figure 2 shows that the deviation calculated as 100 * (1 À q Literature /q This work ) between our measurements and the available literature data are mainly less than 0.125% similar to the comparison presented in reference [5] which indicates 0.1%.…”

“…15) K. Figure 1 shows their molecular conformation. Concerning these compounds, to our knowledge, the previous measurements have only been made at atmospheric pressure [4][5][6][7][8][9][10]. The isobaric thermal expansivity, a p = À(1/q)(oq/oT) P , and isothermal compressibility, j T = (1/q)(oq/op) T , have also been derived.…”

“…The review of the currently available literature sources reveal that there is a lack of information on the volumetric and thermoelastic properties of amine compounds with a large number of carbon atoms. The database for thermophysical properties of these fluids, at present, is scarce and limited (except for very few cases) to narrow temperature and pressure intervals [1][2][3][4][5][6][7][8][9][10]. Mention some densities values up to 200 MPa, between (273.1 and 373.3) K, for trimethylamine [1], up to 34 MPa at 298.15 K for n-butylamine and propylamine [2,3].…”
