蔚r and
values are reported for (1-alkanol + cyclohexylamine) systems at T = (293.15 to 303.15) K.- •
- (蠒1=0.5) values decrease as: 1-propanol > 1-butanol > 1-heptanol < 1-decanol.
- •
The
curves become skewed to higher 蠒1 values when the alcohol size increases.- •
This is due to the weaker and lower self-association of longer 1-alkanols.
- •
Similar trends are observed for alcoholic solutions with cyclohexane, aniline or DPE.
