- - Principle of test: Two independent experiments have been developed in this study. The first is a measurement of solubility, using a saturated aqueous solution. The second procedure involves stripping the solute by a gas stream and gives the
product γ∞P° (Activity Coefficient at Infinite Dilution γ∞ and Vapor Pressure P°). Results obtained by the two methods allow vapor pressure calculation.
- Short description of test conditions: Stripping experiments were performed in a Biostat MD (B.Braun Biotech International, Melsungen, Germany) bioreactor with a jacketed vessel of total volume 7.5 L (height 38 cm, diameter 16 cm) having an internal concave bottom section. It was fitted with a stirrer shaft with three six-blade impellers 4 cm in diameter. The temperature was regulated at (25 ( 0.1) °C by means of a PID controller, the input air flow at 0.3 standard volume of gas per volume of liquid and per min by a mass flow controller (Bronkhorst, Ruurlo, The Netherlands), and the stirring speed was 1000 rpm. The volume of aqueous solution was 3 L (height of standing liquid 15.5 cm) and a probe (dissolved oxygen) port was kept opened on the top plate. No condenser was used. - GLP compliance:

Based on results from these two experiments, the vapour pressure of L-alpha pinene was calculated to be 529 Pa at 25 ºC (95 % confidence limits: 456 – 602 Pa).

Weight of evidence. L-alpha pinene. EPI-Suite, MPBPWIN v1.43. The vapour pressure of L-alpha pinene is 536 Pa at 25 ºC.
Weight of evidence. Test substance (reaction mass). Based on reported data, the vapour pressure for each main component has been established as follows: 335 Pa for l-camphene and d-camphene based on the experimental value of camphene as a conservative approach, 529 Pa for l-alpha pinene (experimental value) and 661 Pa for fenchene (estimated value). The total vapour pressure of the test substance has been calculated as a first step by the Raoult's law to determine the partial vapour pressure of each component and then, by the Dalton's law to calculate the total pressure as the sum of partial pressures of the main constituents. The vapour pressure of the test item was determined to be 408 Pa at 25ºC.
