Title:
METHOD FOR PRODUCING (METH)ACRYLATE MIXTURE AND METHOD FOR PRODUCING RENEWABLE RESOURCE-DERIVED (METH)ACRYLATE MIXTURE
Document Type and Number:
WIPO Patent Application WO/2023/234232
Kind Code:
A1
Abstract:
[Problem] To provide a production method by which a desired (meth)acrylate mixture can be obtained at extremely high yield by using a renewable resource-derived raw material, environmental load reduction is significant, the obtained mixture has excellent curability, and a cured product thereof has excellent various physical properties. [Solution] This method for producing a (meth)acrylate mixture sequentially carries out the following steps: step 1 which is a step for reacting (meth)acrylic acid with an alcohol having at least three hydroxyl groups in the presence of an acid catalyst to obtain a reaction solution having a specific hydroxyl value; step 2 which is a step for carrying out the following step 2-1 or step 2-2 to obtain a product having at most a specific hydroxyl value, where step 2-1 is a step for adding dicarboxylic acid, diol, and (meth)acrylic acid to the reaction solution of step 1 to obtain a product, and step 2-2 is a step for adding dicarboxylic acid and hydroxyalkyl (meth)acrylate to the reaction solution of step 1 to obtain a product; and step 3 which is a step for neutralizing the reaction solution of step 2 with an aqueous solution of ammonia or/and an amine compound.
