Patent ID: 8317887

Claim:
A composition used as an odorizer for a gaseous fuel, comprising: at least one alkyl acrylate (I) in which the alkyl radical contains from 1 to 12 carbon atoms; and at least one compound of formula (II) in an amount of from 50 ppb to 1000 ppm by weight relative to said alkyl acrylate (I) which inhibits the polymerization of the alkyl acrylate (I) and which is stable in the absence of oxygen in which: R 1 and R 2 , which may be identical or different, each represent a tertiary or secondary hydrocarbon-based radical containing from 2 to 30 carbon atoms, and optionally one or more heteroatoms chosen from phosphorus, nitrogen or oxygen; or R 1 and R 2 , taken with the nitrogen atom to which they are attached, form a cyclic hydrocarbon-based radical containing from 4 to 10, said radical being optionally substituted, said composition being essentially free of alkyl sulfide.
