| titleOfInvention | Process for producing polyethylene glycol dibenzoates |
| abstract | (57) [Summary] (Modifications) [PROBLEMS] To provide a method for producing polyethylene glycol benzoates having a low content of ethylene glycol dibenzoate and a good color tone. SOLUTION: General formula (1) [Wherein, R 1 is hydrogen, an alkyl group having 1 to 10 carbon atoms, Represents a cycloalkyl group having 3 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a phenyl group or a chlorine atom; Represents an integer of 1 to 3. And a general formula (2) [In the formula, n represents an integer of 2 to 200. A method of producing a polyethylene glycol dibenzoate by subjecting the polyethylene glycol represented by the formula [1] to an esterification reaction in the presence of a catalyst, characterized in that a tin compound is used as the catalyst. Method for producing esters. |
