Claim 0:
1. An acetylene fluid supply package, comprising:
a pressure vessel;, a porous filler in the pressure vessel;, an improved solvent within the porous filler, said solvent solubilizing with acetylene absorbed within the improved solvent;, said improved solvent comprising all of the following attributes:
(i) a vapor pressure at 20 deg of approximately 6 torr or less;
(ii) a Hansen solubility factor (dH) greater than about 5 MPa0.5;
(iii) higher non-toxicity in comparison to dimethylformamide (DMF) and N-methylpyrrolidone (NMP); and
(iv) a chemical structure comprising O, N or F atoms, wherein at least one of said O, N or F atoms is not bonded to a hydrogen atom, and further wherein said chemical structure is characterized by an absence of phosphorus boron, calcium and nickel;
wherein the improved solvent is mesityl oxide, said mesityl oxide loaded into the pressure vessel in an amount no greater than about 0.54 kg of mesityl oxide per liter of volume of the pressure vessel.
