MANUFACTURING METHOD OF β-HYDROXYLACTONE (METH)ACRYLIC ACID ESTER
PROBLEM TO BE SOLVED: To provide a method capable of manufacturing (meth)acrylic acid ester of β-hydroxylactone at high yield with almost no side reaction. SOLUTION: The problem is solved by a manufacturing method of β-hydroxylactone (meth)acrylic acid ester for providing corresponding (meth)acrylic acid ester by reacting specific β-hydroxylactone (B) and at least one kind of acid anhydride (C) selected from (meth)acrylic acid anhydride (C1) and anhydride of (meth)acrylic acid and carboxylic acid other than the (meth)acrylic acid (C2) in presence of a specific Lewis acid catalyst (A).
