Abstract: A process for inhibiting polymerization in the preparation of (meth)acrylic esters of specific alcohols involves: controlling pH of the water to greater than 7 (preferably >=8, especially >= 9) while reacting (meth)acrylic esters with specific alcohols. A process for inhibiting polymerization in the preparation of (meth)acrylic esters of 1-8C alcohols involves: controlling pH of the water to greater than 7 (preferably >= 8, especially >= 9) while reacting (meth)acrylic esters with 1-8C alcohols.
