    • A gas generant is provided which decreases toxic components, in particular carbon monoxide and nitrogen oxides, in generated gas to a concentration practical as an air bag system for automobile. A nitrogen-containing organic compound such as a compound containing amino group or amido group or a tetrazole derivative and a oxygen-containing inorganic oxidizer such as KNO3, Sr(NO3)2 or KClO4 are essential components. Therewith one or more metal oxides are contained in the mixed catalyst of the gas generant composition. The oxide is selected from manganese dioxide having a specific surface area not less than 50 m2/g; copper oxide having a specific surface area not less than 1 m2/g; molybdenum oxides such as molybdenum dioxide, molybdenum trioxide, molybdic acid and ammonium molybdate: and copper oxides, cobalt oxides, iron oxides and silver oxides.

    • A carbonylation catalytic system comprises (A) a combination of (A1) a Group VIII metal source of Periodic Table of the Elements (e.g., palladium, palladium chloride) supported on a carrier, (A2) a ligand such as triphenylphosphine and (A3) an acid such as an alkylsulfonic acid, or (B) a combination of (B1) the Group VIII metal source except for palladium (e.g., a platinum compound), (B2) a ligand such as triphenylphosphine and (B3) an electron donative compound having an electron donability .DELTA..nu.D of not less than 2 (for instance, an amine such as a heterocyclic tertiary amine). The catalytic system (B) may further comprise (B4) an acid such as methanesulfonic acid. In the presence of the catalytic system (A) or (B), an acetylenic or olefinic unsaturated compound is allowed to react with carbon monoxide and a nucleophilic compound having an active hydrogen such as water, an alcohol and a carboxylic acid in a liquid phase to give an unsaturated or saturated carboxylic acid or an ester thereof with high transformation rate and selectivity.
