Sulfonic acid-type catalysts useful in, for example, esterification reactions |
| abstract |
Sulfonic acid catalysts useful in, for example, esterification reactions and which contain an admixture of any of several phosphorus compounds including specifically ortho-phosphoric acid are much less corrosive toward metal processing equipment than are sulfonic acid catalysts without the phosphoric admixture. |
