Physical and Thermodynamic Properties of Terpenes.¹ III. The Vapor Pressures of α-Pinene and β-Pinene²

Chemical Characterization of Gas- and Particle-Phase Products from the Ozonolysis of α-Pinene in the Presence of Dimethylamine

“…In experiments E1-E3, 100-120 ppb (Table 1) Figure S1). The concentration of α-pinene was estimated from the vapor pressure 28 and the measured gas flows. Finally, ~ 500 ppb of DMA was introduced in the flow tube (Experiments E1'-E3') to investigate the impact of amines on the ozonolysis of α-pinene.…”

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

“…In the work of Medeiros et al [8], the purity of a-pinene, b-pinene, was respectively, 99.88 % and 98.14 % and the b-pinene was purified by fractional distillation under vacuum. Langa et al [9] also measured the density of b-pinene at three temperatures, between 283.15 K and 313.15 K, using 99% purity commercial samples, without further purification.…”

“…15 Later Sousa and Nieto de Castro [7] measured the densities of commercial samples of a-pinene, b-pinene, limonene and two types of turpentine also at atmospheric pressure at temperatures between 293.15 K and 313.15 K. Gomes-Medeiros et al [8] studied densities and kinematic viscosities of mixtures containing a-pinene + b-pinene at temperatures between 298.15 K and 363.15 K. These terpenes were obtained once again by distillation from turpentine. Hawkings and Amstrong [9] measured the vapour pressures of a-pinene (between 292.6 K and 428.91 K) and b-pinene (between 291.87 K and 413.15 K). Densities and speed of sound of pure b-pinene were studied by E. Langa et al [10] within the temperature range from 283.15 K to 313.15 K. Sampaio and Nieto de Castro [11] determined the isobaric heat capacity of commercial samples of a-pinene, b-pinene, limonene and turpentine at temperatures between 313 K and 403 K. However, there is no experimental work on P, q, T behaviour of (a-pinene + b-pinene) at high pressures, nor Cp of their mixtures at ambient pressure.…”

Isothermal and isobaric (vapour+liquid) equilibria of (α-pinene+n-butanol+n-octane)

“…a-Pinene, 2,6,6-trimethylbicyclo[3.1.1]hept-2-ene (CAS RN 80-56-8), presented in wood turpentine, one of the intermediates of vitamin synthesis, is a leuco transparent liquid with a strong odor [1]. The binary isobaric (vapour + liquid) equilibria (VLE) data for a-pinene with terpene hydrocarbons, and isothermal VLE data for a-pinene with alkanes, alkenes, and n-alkanols are available in the literature [2][3][4][5].…”
