Although the quantity of acetone in the product under consideration 

 is sufficiently large to render further purification necessary, it is 

 evidently much smaller than is usually observed in commercial wood 

 spirit. 



Allyl Alcohol. 



The occurrence of allyl alcohol as a product of the distillation of 

 wood was first mentioned by Aronlieim,* and soon afterward Kramer 

 and Grodzkyt stated that small quantities of it may always be found in 

 the higher fractions. In examining the aqueous part of the residue in 

 (c) for this substance, after removing the water, a small amount of an 

 oil was left, with a boiling point somewhat higher than that of allyl 

 alcohol. It absorbed bromine readily, Avith the formation of a product 

 which boiled much too low for dibromallyl alcohol, and oxidation with 

 nitric acid gave only oxalic acid. Since from the results of Kramer 

 and Grodzky it is usually present in wood spirit, in quantity not ex- 

 ceeding two tenths of one per cent, it is evidently possible that the 

 small amount contained in 2,000 grms. might escape observation.

composition of the higher boiling fractions was not 

 sufficiently desirable accuracy, a brief description of 

 solate substances which have already been found in 

 portions of wood spirit may have some interest. It 

 mentioned, that beside water these fractions consisted 

 and an oil lighter than water. The heavier oil was 

 of furfurol, though, as well as the water and lighter
