Odorizing methane-rich fuel gases, especially natural gas, comprises adding a mixture of an alkyl (meth)acrylate and a phenolic compound

摘要

Odorizing fuel gases with a methane content of at least 60 wt.% comprises adding a mixture of a C1-C6 alkyl (meth)acrylate and a phenolic compound (I) and optionally an antioxidant. Odorizing fuel gases with a methane content of at least 60 wt.% comprises adding a mixture of a C1-C6 alkyl (meth)acrylate and a phenolic compound of formula (I) and optionally an antioxidant: R1 = H, Me or Et; R2-R4 = H, 1-4C alkoxy, 1-4C acyl, 1-5C alkyl or 2-5C alkenyl; alternatively, R1+R4 forms a 5- to 7-membered ring containing at least one C atom and up to two N atoms, optionally substituted with 1-4C alkoxy or 1-4C alkyl. An Independent claim is also included for a fuel gas with a methane content of at least 60 wt.% containing a C1-C6 alkyl (meth)acrylate and a compound (I) and optionally an antioxidant.
