Process for preparing low-acid-value phosphoric esters |
| abstract |
A process for preparing low-acid-value phosphoric esters is characterized by treating a phosphoric ester having a certain acid value with an organic ortho-acid ester. The phosphoric ester is preferably one having a specific structure, while the organic ortho-acid ester is preferably a C1-C4 alkyl ester of orthoformic, orthoacetic or orthopropionic acid. |
