Thermolysis of sulfate turpentine was studied in the pressure range of 40–280 atm. The conversion kinetics of main turpentine components (α-pinene, 3-carene) and their isomerization products (limonene, alloocimenes, pyronenes) was investigated and compared with the conversion kinetics of these compounds in supercritical ethanol. Thermodynamic parameters View the MathML source, View the MathML source and View the MathML source of the reversible reaction “α-pinene-[TS]” were estimated, the observed discrepancies being interpreted in the context of transition state theory. The thermolysis rate of α-pinene as a turpentine component was compared to that in a supercritical diluted solution of ethanol versus pressure. The rate of α-pinene conversion was shown to depend on the density of working medium.
