In a process to sterify (meth)acrylic acid with an alkanol in the presence of a sterification catalyst, wherein non-converted initial compounds and (meth)acrylate to be formed are distill separated and a bottom product containing oxyesters is formed, the bottom product is separated first, oxyesters contained therein are then distill separated and the resulting product is dissociated in the presence of acids at high temperatures. The process can be performed in the presence of molecular oxygen. The distillate is dissociated at temperatures within the range from about 170 degree C to about 250 degree C, preferably from about 180 degree C to about 230 degree C.
