By weighing it as benzoic acid, obtained either by precipitation, or by very careful sublimation in a glass apparatus:—2.
Divide into 350 lozenges, and finish as with benzoic acid lozenges.
Like the benzoic acid the acetic acid is, no doubt, present in cananga oil in the form of ether.
Treated with nitric acid, some hydrocyanic acid is formed, benzoic acid sublimes, and the residual matter is artificial tannin:—8.
Some of the largest wholesale perfumers use five or six pounds of gum benzoin per annum, but none use the benzoic acid.
It can be hydrolyzed, by a special enzyme, into salicin and benzoic acid.
Nitration of benzoic acid gives chiefly meta-nitro-benzoic acid.
benzoic acid, like the aldehyde, is a natural product which has long been known.
If the solution of the salts of this acid is too dilute and warm, none or only a portion of the benzoic acid will be separated.
Suspend the benzoic acid in 10 parts of water, add the lithium carbonate, and heat.
