More Information
Summary:The invention relates to a process for recovery of noble products from heavy (meth)acrylic fractions generated during production of (meth)acrylic esters by transesterification, the heavy fractions comprising at least noble products and Michael adducts, the process comprising the steps of: (i) adding at least one antifouling agent and optionally a viscosity-reducing compound to the heavy fractions; (ii) submitting the mixture to temperature and distillation conditions sufficient to crack the Michael adducts into their components; and (iii) recovering the noble products in the form of a stream of distillate, and of a final residue that is sufficiently fluid to be transported by pump.
