Summary
-
1.
The aldehyde yield from cotton steins is approximately twice that from pods and seed husk, in spite of the fact that the lignin content (by the Konig method) is the same in all these types of material.
-
2.
The aldehyde mixtures obtained from stems, pods, and seed husks contain the same amount of methoxyl groups, which indicates the comparatively uniform composition of the lignins from different parts of the cotton plant.
-
3.
Not all the aldehyde mixtures contain p-hydroxybenzaldehyde.
