Not illustrated. 1913 edition. Excerpt: ...below those of turpentine, 5 per cent; (2) refined turpentines or "hearts," 65 per cent; and (3) "heavy oils" or "tails" with boiling points and gravity above those of turpentine, 30 per cent. In order to secure such a separation in the refining still it was necessary to regulate' the flow of the different products to the following speeds (the crude turpentine running at 25 gallons per hour): For heads 5 per cent of 25, or 1.25 gallons per hour. For hearts 65 per cent of 25, or 16.25 gallons per hour. For tails 30 per cent of 25, or 7.5 gallons per hour. In the distillation of this turpentine and all others as well the first runnings of the distillates were caught separately until the adjustment was completed, because the composition of the products would vary greatly at first. The analyses shown hereafter represent the composition of the products obtained after the still was properly adjusted and running smoothly. For instance, this run on turpentine No. 1 occupied about 44 hours, but the products shown in the analyses were obtained during a little less than 4 hours of this time. Fig. 22.--Boiling point, specific Kravity, and index of refraction curves for crude turpentine No. 2, after treatment with caustic soda solution. PRODUCTS OF DISTILLATION. The analyses of the products obtained from, the distillation of crude turpentine No. 1 are shown in figures 23, 24, and 25. HEADS. The heads (fig. 23) vary greatly in composition, and approximately the first 70 per cent have higher indices of refraction, and Pig. 23.--Boiling point, specific FlG. 24.--Boiling point, specific gravity, and index of refraction gravity, and iDdex of refraction curves for "heads" obtained in curves for "hearts-obtained...
