DEFINITION

Classification: 435/61

Dehydrogenating; dehydroxylating:

(under subclass 52) Processes wherein the product synthesized is produced by the removal from the nucleus of a pair of hydrogen atoms creating an unsaturated bond or the product is synthesized by removal or addition of a hydroxyl group.

(1) Note. The mere shifting of unsaturated bonds from adjacent positions such as from the 5, 6 position to the 4, 5 position is not a dehydrogenation.
