摘要

Device for the preparation of acid acrylic paint, process for the preparation of acid acid, acrylic paint, acrylic paint, process for the preparation of a polu00ecmero hidrofu00eclico, polu00ecmero hidrofu00eclico, method for the production of an absorbent article of hygiene water, fibers, molded articles, fi. LMEs, foams, polu00ecmeros superabsorbent, detergents,Polu00ecmeros special for the fields of wastewater treatment, emulsao paints, cosmetics, textiles, leather goods and production of paper or toilet articles, and the use of an acid acrylic paint.The present invention relates to a device (1) for the preparation of acrylic acid, comprising: - a first reactor (2); and - at least one another reactor (3), in which at least the first reactor (2) is a reactor multitubo, having a plurality of tubes (4) comprising a catalyzed R, which catalyzes the synthesis of acroleina; - in which the tubes (4) are opened in a collection chamber (6),That can be connected smoothly to at least another reactor (3), a region of discharge (7) and in which the region of discharge (7) comprises a means of lamelau00e7u00e3o (8), which causes the lamelau00e7u00e3o a profile of flow of a gas flowing through the region of discharge (8).The invention also relates to a process for the preparation of acrylic acid, an acrylic acid, a process for the preparation of a hydrophilic polymer, a hydrophilic polymer, a method for the production of an absorbent article of hygiene water, chemicals, Such as fibers, molded articles or films, and also to the use of an acrylic acid.
