摘要:The invention relates to a method for producing acrolein, comprising the
following steps: (a) dehydrating an aqueous glycerin phase G1 in an acrolein reactionregion, obtaining an aqueous acrolein reaction phase; (b) at least partially separating theaqueous acrolein reaction phase into an acrolein-rich acrolein phase and an acrolein-poor(in comparison to the acrolein phase) residual phase R1, wherein the residual phase R1comprises glycerin, water and various remainders from glycerin and water; (c) recycling atleast a part of the residual phase R2 in step (a); wherein i) from a glycerin phase G2comprising remainders that differ from glycerin and water, at least one of said
remainders is separated and the thus obtained, purified glycerin phase G2 is immediatelysupplied to the acrolein reaction region, or ii) at least one remainder different fromglycerin and water is separated out of a mixture phase M1 obtained by mixing a glycerinphase G2 with the acrolein-poor residual phase R1, and the thus obtained, purifiedmixture phase M1 is supplied to the acrolein reaction region. The invention furthermorerelates to a method for producing acrylic acid, water-absorbing polymer formations,compounds and hygiene articles, to devices for carrying out the method and their
application, to a method for purifying a glycerin phase and to the application of a glycerinphase.
