| titleOfInvention | Preparation of c8-c24 alkyl (meth)acrylates |
| abstract | The invention relates to a process for preparing a C 8 -C 24 alkyl(meth)acrylate by transesterification of methyl(meth)acrylate with a C 8 -C 24 alkanol, said process comprising the steps of: n (i) reacting methyl(meth)acrylate with the C 8 -C 24 alkanol in the presence of a tin-comprising catalyst and a stabilizer in the presence of an entraining agent which forms an azeotrope with methanol, n (ii) continuously distilling off the azeotrope of entraining agent and methanol wherein steps (i) and (ii) are carried out simultaneously until the C 8 -C 24 alkanol has been substantially completely reacted, n (iii) washing with an aqueous alkaline washing solution the C 8 -C 24 alkyl (meth)acrylate-comprising product mixture obtained in steps (i) and (ii) to remove from the product mixture the tin-comprising catalyst and at least some of the stabilizer, n (iv) distilling off unconverted methyl(meth)acrylate and entraining agent from the product mixture, n (v) distilling off water from the product mixture n wherein a product having a by-product content of < 0.5 % by weight is obtained after step (v) and step (iv) may also be carried out before step (iii) and steps (iv) and (v) may also be carried out in one distillation step. |
