Agamassan (aga) is a substrate used to safely absorb acetylene and thus allow the transport, storage and commercial explotation of an otherwise unstable gas. It was developed by Nobel Laureate Gustaf Dalén who would later invent the AGA cooker Look up substrate in Wiktionary, the free dictionary. ... Acetylene (systematic name: ethyne) is the simplest alkyne hydrocarbon, consisting of two hydrogen atoms and two carbon atoms connected by a triple bond. ... Nils Gustaf Dalén (November 30, 1869 – December 9, 1937) was a Swedish inventor and industrialist, the founder of AGA, who was awarded the Nobel Prize in Physics in 1912 for his work on automatic gas regulator controlled buoys. ... AGA is the abreviation of the company name Aktiebolaget Gas Accumulator. ...

Acetylene can readily explode when in liquid/solid form or if pressurised beyond approx 100 kPa. (Dalen was blinded in an acetylene explosion).

It is shipped and stored dissolved in acetone or dimethylformamide (DMF), contained in a metal cylinder with porous filling (Agamassan), which renders it safe to transport and use. In chemistry, acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is the simplest representative of the ketones. ... Dimethylformamide (DMF, N,N-dimethylformamide) is a clear liquid, miscible with water and majority of organic solvents. ...
