Advantage is taken, as explained in Chapter XI., of the high degree of
solubility of acetylene in acetone, to employ a solution of the gas in
that liquid when acetylene is wanted in a portable condition. The
solubility increases very rapidly with the pressure, so that under a
pressure of twelve atmospheres acetone dissolves about 300 times its
original volume of the gas, while the solubility also increases greatly
with a reduction in the temperature, until at -80 deg. C. acetone takes up
2000 times its volume of acetylene under the ordinary atmospheric
pressure. Further details of the valuable qualities of acetone as a
solvent of acetylene are given in Chapter XI., but it may here be
remarked that the successful utilisation of the solvent power of acetone
depends to a very large extent on the absolute freedom from moisture of
both the acetylene and the acetone, so that acetone of 99 per cent.
