P, ρ, T and heat capacity measurements of (α-pinene+β-pinene) mixtures over the temperature range 283.15K to 358.15K and pressures up to 40MPa: Experiments and modelling

Rapid Vapor-Collection Method for Vapor Pressure Measurements of Low-Volatility Compounds

“…Vapor pressure (p sat ) data are essential to the design and optimization of chemical separations and purifications. 1,2 Environmental models also require accurate p sat data to predict the lifetime and fate of pollutants. 3,4 Forensic science makes use of p sat data in a variety of scenarios such as detection of explosives or intoxication.…”

“…Vapor pressure ( p sat ) data are essential to the design and optimization of chemical separations and purifications. , Environmental models also require accurate p sat data to predict the lifetime and fate of pollutants. , Forensic science makes use of p sat data in a variety of scenarios such as detection of explosives or intoxication. , Indoor exposure to a variety of substances depends on p sat . − Nevertheless, the lack of p sat data for low-volatility compounds is often lamented. ,,, There are two primary reasons for this. First, there is a dearth of commercial instruments to measure the p sat of low-volatility compounds.…”

Thermodynamic Analysis of α‐Pinene and Limonene Allylic Oxidation over a FePcCl16‐NH2‐SiO2 Catalyst

“…3-6 compare the reported simulated and experimental data for liquid heat capacities of a-pinene, verbenol, verbenone, and limonene. Also, some differences for the reported experimental heat capacity values of some compounds (Exp1 [27], Exp2 [28], Exp3 [29], Exp4 [30], and Exp5 [31]) are observed. In the case of verbenol, the differences between experimental and simulated values at temperatures above 373 K could be related to verbenol decomposition after reaching the melting point in the experimental analysis [28].…”

Thermal stability and oxidation characteristics of α-pinene, β-pinene and α-pinene/β-pinene mixture

“…In the experiment, Δ T obs is obtained, the relationship between Δ T and Δ T obs is shown in eqn (1) : φ = Δ T /Δ T obs = 1 + ( M b × C b )/( M s × C s ) where φ is thermal inertia (often referred to as the phi-factor); M b is bomb mass, M b = 8.0 g; C b is specific heat of bomb, C b = 0.130 J g −1 K (material is titanium); M s is sample mass; C s is specific heat of sample. 38 ARC is an experimental device simulating adiabatic condition, under adiabatic condition, the calculation equation of reaction activation energy ( E a ) is as follows ( eqn (2) ): 39–41 E a = R ( T 2 × T 1 /( T 2 − T 1 )) × ln(( t 1 × T 2 2 )/( t 2 × T 1 2 )) where T is the temperature, t is the time, and R is the gas constant. At the end of the experiment, E a was obtained from the software.…”
