Description
Excerpt from Organic Chemistry for Advanced Students, Vol. 1: Reactions
The Radical of Benzole Acid. In the year 1832 Liebig and Wohler published their classical memoir, entitled, 'Experiments on the Radical of Benzoic Acid'.
Viewed in the light of our present knowledge there is nothing very remarkable in the facts which they discovered. Starting with bitter almond oil, which we now term benzaldehyde, they converted it by the action of chlorine and bromine into benzoyl chloride and bromide. Benzoyl chloride treated successively with potassium iodide gave benzoyl iodide; with ammonia, benzamide; with lead sulphide, benzoyl sulphide; with mercuric cyanide, benzoyl cyanide and with alcohol, benzoic ether. Bitter almond oil had, moreover, been found by Stange (1824)to undergo rapid oxidation in the air and to be transformed into an acid - benzoic acid - identical with the substance derived from gum benzoin.
Such is briefly the substance of the investigation to which the following introduction is attached. 'When a chemist is fortunate enough to perceive one ray of light penetrating the dark region of organic nature, which may mark the entrance to the right path of future knowledge, he has reason to feel encouraged, although conscious of the vastness of the field which lies before him.'
In order to realize the importance of a memoir which created a profound impression among contemporary chemists, and was welcomed by Berzelius as 'the dawn of a new day', we must take a glance at the branch of chemistry which at this period formed 'the dark region of organic nature'.
