Originally published in 1922 this book has been revised since its first publication-which placed emphasis on fractional distillation-to include distillation on a large scale as carried out in the manufacture of important products. Distillation Principles and Processes covers the research of scientists in fields including: Acetone and n-Butyl Alcohol, Alcohol, Petroleum, Coal Tar, Glycerine and Essential Oils.

2 a) Es sind 2 Stoffe zugegen, deren Siedepunkte sehr nahe beieinander liegen; b) ein oder mehrere Bestandteile sind in prozentual sehr geringer Menge im Gemisch enthalten; c) es bilden sich konstant siedende Gemische. Die Trennung zweier Fliissigkeiten kann, selbst Wenn ihre Siede 0 punkte 20-30 auseinander liegen, infolge der Bildung eines Ge misches mit: Minimum- oder seltener mit Maximum-Siedepunkt unmog lich werden, wie es z. B. bei Athyl-Alkohol und Wasser, oder Benzol und Isobutyl-Alkohol der Fall ist. Die Annahme, daB die Schwierigkeit der Trennung der Bestandteile eines Gemisches mit wachsender Siede punktsdifferenz der Bestandteile abnehme, trifft in Wirklichkeit nur unter der Voraussetzung zu, daB chemisch ahnliche Korper zu trennen sind. In allen anderen Fallen muB man die Beziehungen, die zwischen den Siedepunkten bzw. Dampfdrucken von Stoffgemischen einerseits und ihrer Zusammensetzung andererseits bestehen, in Betracht ziehen, und solange nichts iiber die Form der Kurve bekannt ist, die die eine oder die andere dieser Beziehungen darstellt, ist es unmoglich zu sagen, ob die Trennung leicht, oder auch nur, ob sie iiberhaupt moglich ist. Die Formdieser Kurven hangt weitgehend von dem Grade der chemischen Verwandtschaft der Bestandteile ab, und es ist neuerdings in einer beschrankten Zahl von Fallen moglich, aus der chemischen Konstitution der Stoffe auf den Grad der Abweichung der 'Kurven von der Normalform zu schlieBen und damit das Verhalten einer Mischung bei der Destillation vorauszusagen."
