“…Isobaric VLB information for -pinene + 3-pinene and for these pinenes with other terpene hydrocarbons like limonene, terpinolene, A3-carene, p-cymene, and 1,8-cineole is available in the literature (3)(4)(5)(6)(7). Only recently, isothermal P-x-y VLB data for -pinene and 3-pinene with heptane, cyclohexane, 1-octene, cyclohexene, 1-butanol, and 1-pentanol, and infinite dilute activity coefficients for these same systems and with aromatics and ethers have been measured and published (8)(9)(10).…”
