摘要

Processes for the production of acroleu00ecna acid, acrylic paint, water absorbent polymer structures and composite device for dehydration and oxidation, polymer water absorbent composite structures, and the use of acid acrylic paint products.The present invention relates to a process for the production of acrolein comprising the following steps: (a) bringing an aqueous phase of acroleina to an area of acroleina reaction to obtain an aqueous phase reaction acroleina; (b) depletion acroleina from a phase of a Eau00e7u00e3o of acroleina to obtain a acroleina phase and a phase reaction of acroleina removed; (c) drive inReturn at least part of phase reaction acroleina removed to the area of reaction of the acroleina.The invention also relates to a process for the production of acrylic acid as well as structures of polymer water absorbing composite, in particular articles of hygiene, understand these structures of polymers absorbing water.A process for the production of composite and also chemical products based on acrylic acid obtained by the process of the invention, and the use of acrylic acid in chemical products.
