Abstract: A process for coating a metallic surface of a metallic substrate comprising applying, an organic, anionically, cationically or radically curable anticorrosive composition, to the metallic surface, wherein said anticorrosive composition is a dispersion or solution containing at least two components that are at least partially anionically, cationically or radically curable, wherein at least one monofunctional monomer or monofunctional oliger is present, a photoinitiator, and an first organic corrosion inhibition.

Abstract: A process for purifying an aqueous solution to obtain purified gaseous acrolein by introducing the aqueous solution into a distillation column equipped at its base with at least one boiler and at its top with at least one condenser, withdrawing a liquid mixture essentially containing water at the base of the distillation column, withdrawing a gas essentially containing acrolein and water at the top of the distillation column, cooling the gas mixture withdrawn at the top of the distillation column in the condenser, to a temperature which makes it possible to obtain, on the one hand, an aqueous condensate and, on the other hand, an acrolein-rich gas mixture, and withdrawing the acrolein-rich gas mixture.

Abstract: A process for the production of methionine which comprises (a) hydrolysing the methionine amide in the presence of a catalyst comprising titanium to produce ammonium methioninate, said catalyst having a porosity of from 5 to 1000 nm, a total pore volume of from 0.2 to 0.55 cm3/g and a surface area of from 30 to 150 m2/g, and (b) a second step of recuperating methionine from the ammonium methioninate salt by removing ammonia. Also claimed is an industrial process for the production of methionine incorporating the aforementioned hydrolysis.

Abstract: The invention relates to a continuous method for the purification of acrolein, wherein: an aqueous acrolein solution is supplied, devoid of gas which is difficult to condense, in a distillation column fitted with at least one boiler at the base thereof and with at least one condenser at the head thereof; a mixture which essentially contains water is drawn off at the base of the distillation column; a mixture which essentially contains acrolein and water is drawn off at the head of the distillation column; the mixture drawn off from the head of the distillation column is cooled in the condenser to a temperature enabling an aqueous condensate to be obtained, in addition to a substantial amount of a gaseous mixture which is rich in acrolein; the purified acrolein is isolated in the gaseous mixture which is rich in acrolein.
