Thermodynamics of Mixtures Containing Amines. XV. Liquid–Liquid Equilibria for Benzylamine + CH3(CH2)nCH3 (n = 8, 9, 10, 12, 14)

Coexistence curves for the liquid−liquid equilibria (LLE) of 1-phenylmethanamine (benzylamine) + CH3(CH2)nCH3 (n = 8, 9, 10, 12, 14) have been determined using the critical opalescence method by means of a laser scattering technique. All of the LLE curves show an upper critical solution temperature (UCST), which increases with increasing n. For systems including a given n-alkane, the UCST decreases in the sequence aniline > 2-methylaniline (o-toluidine) > benzylamine > N-methylaniline > pyridine. This means that amine−amine interactions become weaker in the same order. Most of the DISQUAC interaction parameters for the aliphatic/amine (a,n) and aromatic/ amine (b,n) contacts previously determined for solutions with aniline, o-toluidine, or N-methylaniline have been used for the representation of the LLE data. Only the first dispersive interaction parameter of the (a,n) contact has been modified. The coordinates of the critical points are correctly represented by the model

Towards a thermal characterization of a firefighter's protective clothing

Improving the performances of a firefighter cloth-ing require a good understanding of the thermal exchanges between the clothing and the ambient surrounding as well as the firefighter’s body. Indeed, early modelling and experi-mental investigations have revealed the importance of the skin biothermics that should account for sudation and organ-ism thermoregulation [1]. On the other hand, recent fire-fighter clothing technologies have evidenced the multi-layered configuration of the textile, which have to be sepa-rated by several air-gaps to enhance the thermal resistance [2]. A concise analysis on the characterization of multilayer fabrics has highlighted the contribution of convective, radi-ative and conductive thermal exchanges within the clothing-body assembly [3].info:eu-repo/semantics/publishedVersio
