Oil of Cassia. Owing,to the readies with which cinnamaldehyde oxidises, * 
cassia oil almost always contains traces of free cinnamic acid which is unpleasant — S 
inasmuch as it attacks the leads in which the oil is packed, the oil becoming cone 
taminated with lead in consequence. For commercial and medicinal purposes | it is 
therefore recommended to use rectified cassia oil only, which is free from lead. | Ae : 
; As experiments carried out in our laboratories have proved, lead can be removed — 
without difficulty by shaking the oil with tartaric acid. One gram of the powdered — a 
acid is added to 100 grams of oil, the whole is shaken repeatedly and thoroughly and — 4 
allowed to stand for 24 hours when the flocculent deposit is removed by filtration. — 
Oils which gave a very positive lead reaction (shaking a few drops of oil with <a 
containing sulphuretted hydrogen, when the oil drops become coloured red or black, — 
according to the quantity of lead present) showed no trace of lead after above treat: 
ment. Moreover, the colour of the oil had become much lighter and in determining — 
the aldehyde percentage a further advantage was noticeable. For, whereas an exach | 
reading-off of the non-aldehydic contents in the original oils, containing lead, was 
practically impossible on account of the heavy crystalline separation noticeable at the 
division line of oil and aqueous solution, this could*be done with every degree of 
correctness after the oil had been shaken with tartaric acid prior to the aldehyde fest 
for crystalline separations had then practically disappeared. TE ae 
As the process is extremely simple and entails practically no loss of oil, it will 
be found especially suitable for treating small. quantities of oil and should th e 
be of particular interest to the chemist and the druggist.
