Book Description
Excerpt from Wood Turpentines: Their Analysis, Refining, and Composition, Based Upon Experiments at the Forest Products Laboratory at Madison, Wis Figure 18 gives the result of a distillation of a part of the tur pentine used in figure 2, which had been redist-illed several times in order to remove the high-boiling and heavy material originally present. The curves show. That this heavy material, has been en tirely removed, and yet the values for all the physical properties in creased to some extent as the distillation progressed, which indi cated that the distillate was not a pure substance. Evidently, then. The gradual increase of these values in figure 2 was not due to the presence of 7) in the first 95 per cent of the distillate, but instead there must have been present another substance, 0, with physical properties only slightly higher than those of a, the boiling points of a and 0 being so close together that the substances are very incompletely separated by distillation. This interpretation agrees with the results of recent investigations of the chemical constituents usually present in turpentine. Accord ing tosemmler,1 there may be present in American turpentine be sides 'pinene 2 two other terpenes, camphene and nopinene 3. The physical properties of these two terpenes have not been accurately determined, but it is sufficient to know that they are all higher than those of pinene. The first 95 per cent of the distillate from this tur pentine was probably composed of a mixture of pinene with either camphene or nopinene, or both, and the last 5 per cent was made up of materials with much higher physical properties, probably oxida' tion products of the terpenes.

Book Description
Excerpt from Wood Turpentine: Its Production, Refining, Properties and Uses Wood turpentine can be recovered from any of the coniferous woods. Those which have been found to contain sufficient resin to justify working them are the long-leaf yellow pine, of the South, the Norway pine of the Central North, and the Douglas fir of the North west. The methods by which wood turpentine is recovered may be appropriately divided into three classes, (a) destructive distillation methods, (b) steam distillation methods, (a) extraction with solvents.
