46, 1046 (1913), give 147°. " 7 Many of the modifications of the method have been applied on an enormous scale industrially, as m the hardening of fats with the aid of reduced nickel. 9 40 g. of quinine CHCH:CH2 CH fl O are dissolved in 180 g. of 10 per cent aqueous sulfuric acid, filtered, and treated with 8 to 10 cc. of a 2 per cent solution of palladious chloride 10 prepared by dissolving the salt m a little hot 1: 1 hydrochloric acid, concentrating as far as possible on the water bath, and diluting to volume with water.
Portions as the fluid bromine disappears into solution. Kiliani's original method calls for double t h e amount of bromine, but Ruff " found that an e q u a l weight was sufficient. It is well, however, to control ^ the progress of the oxidation by the gradual diminution in reducing power (Fehhng's solution) of the solution, and to use a little more bromine if the reducing powder has not fallen to a minimum after an equal w e i g h t of bromine has reacted. The oxidation may be considered to take place according to the equation: RCHO + Br 2 + H , O > R C O O H + 2HBr.
This salt may readily be obtained by passing dry hydrochloric acid gas through a wide tube into a chilled solution of pyridme in several volumes of benzene. 20 g of o-allylphenol are boiled with 2 g. of dry pyridine hydrochlonde until the boiling point sinks to a minimum10 The solution is diluted with ether and washed with dilute acid to remove the pyndine salt, with dilute sodium hydroxide to remove any unchanged allylphenol, and then with water. After the ethereal layer is dried over sodium sulfate and concentrated the residue is distilled, the a-methylcoumarane boiling at 197-8 0 .
