PREPARATION OF AMIDO ESTER COMPOUNDS |
摘要 |
<p>This invention relates to a process for preparing amido ester compounds. The process involves (I) forming a mixture in a reactor of a phenol derivative and an amido-carboxylic acid at a temperature which ensures at least partial solubility of the phenol derivative and the amido-carboxylic acid, and (II) adding a carboxylic anhydride incrementally to the mixture formed in Step (I) while distilling a by-product carboxylic acid from the reactor. The amido esters are useful as bleach activators.</p> |
