d^,o = 0,8735; «!) = — 9° 8'. It was recognised as linalool already 
bv its odour. With phenyl isocyanate it formed a phenyl urethane 
of the melting point 65°. Chromic acid mixture converted it into 
citral; when heated slowly with formic acid of high percentage, it split 
off water, an occurrence characteristic of some terpene alcohols. 
Linalyl acetate we discovered in a fraction which boiled be- 
tween 70° and 90° (5 mm pressure). The saponification number of 
the oil was 116,3, corresponding to an ester-content of 40,6 percent. 
From the liquid obtained on saponification, an oil of the boiling point 
of linalool could be fractionated, which formed a phenyl urethane of 
the melting point 65° and which for the rest had all the properties 
of this alcohol. In the saponification liquor there was detected, in 
addition to phenyl acetic acid of the melting point 76°, also acetic 
acid. The silver salt formed from it had the silver - content required 
for silver acetate: 
0,1782 grams of the substance left 0,1148 grams Ag.

In order to remove the anthranilic acid ester from the portions 
boiling above 80° (at reduced pressure), the latter were shaken three 
to four times with dilute sulphuric acid. The ester separated from 
the acid solution contained an admixture of a small quantity of a 
basic body with a strong nicotine-like odour, which distilled 
above 110° (6 mm pressure). 
According tho the observations made by us up to the present, 
phenyl ethyl alcohol appears to form a highly important constituent 
of the extract oil. We abstracted this alcohol in a fairly considerable 
quantity, by means of phthalic acid anhydride, from the fractions 
passing over between 80° and 100°. The body was heavier than 
water, and boiled at 215° to 218°. Its phenyl urethane melted 
at 79°. An analysis of this compound gave the following values: 
0,1616 g of the substance yielded 0,0895 g H2O and 0,4426 g COg.

The diphenyl urethane, which had not hitherto been produced, 
melted at 99° to 100^. This body may perhaps be found suitable for 
the detection of the alcohol in cases where it is a question of identify- 
ing the phenyl ethyl alcohol in mixtures of bodies (benzyl alcohol, 
nonyl alcohol), whose phenyl urethanes melt close to 79°. The com- 
pjQund is characterised by great capability of crystallising.
