I did steam distillation on a mass of rosemary and managed to do an IR analysis on it.
On the IR graph, major peaks appeared at 3444, 1602, 1742, and 2925-2881 cm-1.
From classifying the numbers to functional groups, it was surmised that a mixture of borneol (C=C and C=O) and verbenone (-OH group) was isolated.
In isolation of different components by distillation, exactly what factors can affect this method so that an inefficient separation of the oils results?
Thanks. Any help is appreciated.
