On refractionation practically the whole boiled constantly at 150- 
152°/ 200mm. and gave the following results on analysis : — 
0-0972 gave 0-279 COg and 0-0999 HaO, C=78-2, H=ll-4. 
OjgH^gO, requires 0=77-9, H=ll-7 per cent. 
The constants were found to agree well with those quoted for 
linalol : Df§o 0-8596, 1-4581, [a]^^ +12-69°. The presence 
of d-linalol was confirmed by the preparation of the phenyl urethane 
melting at 64-65° and by its oxidation to citral, which was 
readily identified by conversion into citrylidene malonic acid melting 
at 191°, the melting point of which was unaltered on admixture with 
this acid obtained from another source. When treated with 5 per cent 
sulphuric acid the d-linalol gave an excellent yield of terpin 
hydrate. 
Fractions Vll and Vlll . — These two fractions were found to be a 
mixture of d-linalol and methyl cinnamate. On treatment with 
alcoholic potassium hydroxide solution a sparingly soluble potassium 
salt separated which on decomposition yielded pure cinnamic acid. 
On addition of w-ater to the filtrate from the potassium salt an oil 
separated which was found to distil constantly at 150 — 152°/200mm. and 
was identified as d-linalol. The alkaline solution, from which the d- 
linalol had been separated, gave on acidification a further quantity of 
cinnamic acid contaminated with a small quantity of an oily fatty acid 
which was not obtained in sufficient quantity for investigation. These 
two fractions contained approximately 60 per cent, of d-linalol. 
Fraction IX . — This fraction which crystallised on keeping in the 
cold, gave on analysis figures agreeing fairly well with those required 
for methyl cinnamate. 
0-1283 gave 0-3514 CO 2 and 0-0846 HgO, C=74-7, H=7-0. 
CigH^gO.j requires C=74-l, H=6-2 per cent. 
A portion of the oil was therefore hydrolysed with methyl alcohol- 
ic potassium hydroxide solution when a sparingly soluble potassium 
salt separated. This was found to consist of potassium cinnamate, 
the cinnamic acid therefrom melting at 133°. 
0-1615 gave 4334 COg and 0-0787 H^O, C=73-l, H=5-4. 
CgHgOa requires C=73-0, H=5-4 per cent. 
A further quantity of cinnamic acid was isolated from the alkaline 
filtrate after removal of the alcohol and no other acid appeared to be 
present. A special test confirmed the presence of methyl alcohol in 
the ester.
