Process for preparing low-acid-value phosphoric esters |
abstract |
The process for producing a low acid value phosphoric ester of the present invention isncharacterized by comprising treating a phosphoric ester having an acid value with an organicnortho-acid ester. The phosphoric ester preferably has a specific structure. The organicnortho-acid ester is preferably an ester of orthoformic acid, orthoacetic acid or orthopropionicnacid with an alkyl group having 1 to 4 carbon atoms. |
