Description

Patented Nov. 7, 1950 DISPENSING CONTAINER FOR ACETYLENE Martin H. Heeren, Chicago, Ill., assignor to National Cylinder Gas Company, Chicago, 111., a

corporation of Delaware No Drawing. Application March 22, 1945,

Serial No. 584,262

1 Claim. 1

This invention relates to the storing of acetylene under pressure in cylinders or receptacles filled with a solid absorbent material impregnated with an acetylene solvent. Hitherto the solvent used for this purpose has been acetone, but the use of this substance is associated with certain disadvantages arising from its ready volatility. For instance, on rapid discharge of acetylene from a filled cylinder as much as 3% or 4% of the acetone is lost. Further, chilling of the cylinder due to evaporation of acetone on discharge of acetylene cools the cylinder to the point where the solubility of the acetylene in the acetone is appreciably increased. As a consequence, relatively large amounts of acetylene gas are retained in the cylinder instead of being dis-' charged.

It is therefore an important object of the presis stored under pressure in cylinders or receptacles containing a suitable porous absorbent such as the filler disclosed in the patent to Smith No. 1,332,525 comprising Portland cement, diatomaceous earth, asbestos fiber, charcoal and water. This or some other equivalent absorbent filler is impregnated with 2,4 pentanedione (acetyl acetone).

As is usual in acetylene storage technique, the

gas should be dried before contact with a solvent; preferably it should be passed over calcium chloride before and after compression. The usual pressures may be employed, namely from 10 to 30 atmospheres. The amount of acetylene dissolved is the same as that usually taken up by conventional volatile solvents such as acetone.

The loss of 2,4 pentanedione on rapid discharge of acetylene from storage cylinders is but a fraction of the loss noted when acetone is employed as the solvent.

Many details of composition and procedure may be varied within a wide range without departing from the principles of this invention, and it is therefore not my intention to limit the patent granted on this invention otherwise than necessitated by the scope of the appended claim.

I claim as my invention:

Dispensingv container for acetylene gas under pressure comprising a cylinder or receptacle ca.- pable of being closed and of withstanding internal pressure, a porous, absorbent mass filling said cylinder or receptacle, a substantial quantity of 2,4 pentanedione absorbed in said porous mass, and acetylene gas dissolved in said 2,4 pentanedione to be released therefrom for delivery from said cylinder or receptacle when the latter is opened.
