The demand for pure oxygen gas for
medical and other purposes has recently
led TO the construction OF machinery for
separating the gas from air by the agency
OF caustic baryta. which has the proper
ty OF absorbing certain portion OF oxy-
gen In addition 10 what IL already con-
tains, ana OF yielding up again this alb
sorbed oxygen when heated and placed In
a vacuum.
With one part OF an alkaline sulpholeate
and on or two parts OF benzol, carbon d.
sulphide, oil Of turpentine, etc., A. Muller
Jacobs says we obtain perfectly clear
liquids OF an oily constitution which, on
the addition Of a few drops 81 ammonia,
dissolve In water in any proportion. With
the aid OF heat, sulphur, camphOr, thy
mol. naphtOl, phen0l. ETC., may be dis
solved In the sulpholeates In considerable
proportion.
