If the ethyl ester of inactive campholenic acid is reduced according 
to the method indicated by Bouveault and Blanc, there is obtained 
(as Behal^) found), a new alcohol campholenol, isomeric with borneol, 
which has a faint camphor odour, and shows the following constitution: 
(CH3), 
CHg CH 
CH2 — C — CH2 — CHg OH 
Boiling point (760 mm) = 215° to 216°; dgQO = 0,9006; 
When boiled with 6^/q sulphuric acid, the alcohol is converted into 
an oxide C^oH^gO of the melting point 180° to 182°; d^^o^ 0,91 73 ; 
nj)^90= 1,46071. Behal explains this reaction by the addition of 
water to the double -linking, and subsequent loss of water from the 
y-glycol formed. 
Phenyl ethyl alcohol. The general method of production of 
primary alcohols by reduction of the corresponding acid esters, published 
by Bouveault and Blanc 2), is interesting to us in so far, as it has 
led to a new process for obtaining the phenyl ethyl alcohol present 
in rose oil. It is obtained by allowing a solution of one molecule 
phenyl acetic ester in 3 to 4 times the quantity of its weight of absolute 
alcohol, to fall in drops on a quantity of sodium calculated for six 
atoms. It is then heated for several hours on an oil bath, until the 
sodium has disappeared, if necessary with adding more alcohol. After 
cooling, water is added, and the ester which is not attacked is saponified. 
The alcohol and phenyl ethyl alcohol are then distilled off with steam, 
when the latter is at once obtained in the pure state. 
A method for producing phenyl ethyl alcohol published almost at 
the same time by Grignard^), which is said to be based on the 
following equation:

Hc/ +ClMgCH2C6H5 = HC— OMgCI = C6H5CH2CH20H + Mg<^
