Abstract
PURPOSE: To obtain the titled compound, useful as a polymeric stabilizer, in high yield and in simple processes, by reacting an acrylic acid ester with a phenol compound under specific conditions, thereby inhibiting the side reactions in this process and in the following ester exchange process.
CONSTITUTION: The reaction of an acrylic acid ester of formula I (R1 is CH3 or C2H5) with 2,6-dibutylphenol of formula II in the presence of a basic catalyst gives a propionic acid ester of formula III, which is then subjected to the ester exchange reaction with pentaerythritol without isolating and purifying from the reaction mixture to give the titled compound. The reaction temp. in the above first process is 80W95°C, and the molar ratio of the starting materials (I/II) is 1.00W1.07 in order to inhibit the side reactions in the first process, and consequently, the side reactions in the second process. Thus the high purity titled compound, useful as an oxidation inhibitor, etc., can be obtained in high yield without the isolation and purification of the intermediate.
