Chapter 13, Problem 4Q

Interpretation Introduction

Interpretation:

The boiling point for caryophyllene needs to be determined. If the reported boiling point is not at atmospheric pressure, it must be corrected to 760 mm Hg.

Concept Introduction:

The structure of caryophyllene, a terpene is represented as follows:

  

The boiling point of caryophyllene is 129-130⁰C at 14 mm Hg. According to a rule of thumb, for many liquids, the boiling point drops approximately $0.5{}^{\text{o}}\text{C}$ for 10 mm decrease in pressure.
