THE SOLUBILITY AND HEAT OF SOLUTION OF SUC- 
CINIC ACID IN WATER. AND THE PARAFFIN 
ALCOHOLS. 
H. E. FOWLER AND J. N. PEARCE 
The following is the report of an investigation undertaken 
for the purpose of collecting further information concerning 
the influence of solvent upon certain specific properties of solu- 
tions. The solvents chosen, including water, represent the lower 
homologues of the paraffin alcohol series. 
MATERIALS AND APPARATUS. 
Ordinary 95 per cent ethyl alcohol which had been standing 
for several months over quicklime was decanted and distilled. 
The distillate was then allowed to stand .over anhydrous copper 
sulphate for several days, then decanted and again distilled. 
This distillate was. next refluxed over metallic calcium for sev- 
eral hours and again distilled into glass-stoppered bottles, being 
protected during the final distillation by a tube of phosphorus 
pentoxide. 
The remaining alcohols were of Kahlbaum’s “C. P.” grade. 
Except for the preliminary treatment with lime, they were sub- 
jected to exactly the same treatment as was the ethyl alcohol. In 
every distillation a Glinsky fractionating still-head was used and 
only the constant-boiling middle fraction 1 was collected for use. 
The boiling points of the fractions taken were.

Succinic Acid . — A high grade of the “C. P.” acid was further 
purified by the rapid cooling of a; hot saturated aqueous solu- 
tion. The fine white crystals were filtered on a Hirsch funnel, 
sucked dry, then allowed to dry on a porous plate and finally 
allowed to stand over phosphorus pentoxide in a desiccator for 
at least three weeks before being used.
