To provide a novel preparation method of a tertiary alkyl ester of (meth)acrylic acid with at least 4 carbon atoms in an alkyl group, provided that the method is free of disadvantages associated with conventional technology.
The method for preparing the tertiary alkyl ester of (meth)acrylic acid with at least 4 carbon atoms in the alkyl group comprises the steps of: (1) reacting (meth)acrylic acid with at least one olefin of formula I in a homogeneous phase in the presence of an acidic catalyst in a reactor; (2) discharging the obtained reaction mixture (1) from the reactor; (3) separating the discharged reaction mixture (2) into a mixture (3.1) containing the catalyst and a mixture (3.2) containing the target ester and; (4) removing the target ester from the mixture (3.2). (5) In the treatment step (4), at least one compound S containing at least one N-oxyl group is added as a stabilizer.
