Identification

1)Triturate sample with an equal amount of camphor: the mixture liquefies.

2)Dissolve a small sample in 1ml of glacial acetic acid, and 6 drops of sulfuric acid and 1 drop of nitric acid: a red-brown color develops.

3)To 1g sample add 5ml of a solution of sodium hydroxide, and heat on a water bath: a colorless or light  yellow liquid is obtained. To this liquid add 2 to 3 drops of chloroform, while warm, and shake: a yellow-green color develops

4)The sample solution exhibits a maximum absorbance at the wavelength at 279+ 2nm.

Clarity of Solution

Dissolve 3.0g sample in 10ml of ethanol: the solution is clear
