“They get pine resin in their blood and they can’t get away from it.”—Tom Lowry, Senior Director of Natural Resources for the Choctaw Nation Old Hochatown and the Timber Boom Hochatown was once a booming timber town bordering what is today the Ouachita National Forest. On the east si...
The calculations considered mean values of 66% rosin, 22% turpentine, and 12% of other components. The proportions of C in the mixture (m/m) were 52.42% and 19.40%, resulting in a total of 71.81%. Hence, the estimates yielded 718 g of carbon per kg of resin. 2.4. Physicochemical ...
Turpentine oil is extracted from resin by distillation and contains mainly alpha-pinene and beta pinene [29]. Although this lure has a low price [31,56], it trapped only low numbers of Hylobius spp. adults in the current study. The last attractant that was used in this study was ...

Turpentine amounts from treated and untreated trees were qualitatively similar and had an average heating value of 10,369 cal/g (1 cal = 4.1868 J). Lower moisture and increased resin of the treated trees increased the caloric content of the lower 152-cm bolt by 33.1% above controls and of...
Water uptake of radiata pine wood after microwave and superheated steam treatments: sapwood vs. heartwood In addition, MW treatment can accelerate the degreasing process as it discharges some part of the resin and opens some parts of the resin canals. More... H Cao,S Huang,F Yin,... - ...
Gum Turpentine: 5,000 tons High-softening-point Polyterpene Resin: 8,000 tons Highly Hydrogenated Rosin: 5,000 tons All types of Rosin Glycerol Ester or Penta Ester: 10,000 tons Disproportionated Rosin: 5,000 tons Para-menthane Hydroperoxide: 400 tons ...
transports sugary sap as a nutrient. Resin, used to make turpentine, heals wounds in the tree and gives pinewood its characteristic "piney" odor. Resin will often gum up saws and other woodworking tools. The latex, produced on the exterior of the rubber tree, does not affect woodworking ...
The influence of air temperature and precipitation on turpentine content in pine balsamic resinThe pine resin originated from forest districts of the State Forests in Poland where practical tapping was carried out in the years 1966- 1972. The study material was composed of 5757 verified chemical ...
