| titleOfInvention | Compositions and methods for releasing vapor phase corrosion inhibitors |
| abstract | Disclosed are combinations of substances for stimulus-dependent release of vapor phase corrosion inhibitors including: (1) a matrix; (2) at least one symmetrical or asymmetrical carboxylic acid anhydride of at least one first carboxylic acid, (3) at least one salt of at least one second, highly volatile corrosion-inhibiting carboxylic acid, wherein (2) is a non-volatile anhydride or an anhydride with low volatility with a vapor pressure of preferably lower than 1×10 −3 Pa at 25° C. The combination is effective to release the first carboxylic acid(s) by hydrolysis of the anhydride and release the second carboxylic acid(s) of (3) from its salt by proton transfer from first carboxylic acid(s), so that the second carboxylic acid(s) is/are present as a corrosion inhibitor in the vapor phase. Also disclosed are methods for producing and using the combinations for corrosion protection of conventional industrially used metals, in, e.g., packing, storage and transport processes. |
