    • The invention relates to a method for producing acrolein, comprising the following steps: (a) dehydrating an aqueous glycerin phase G1 in an acrolein reaction region, obtaining an aqueous acrolein reaction phase; (b) at least partially separating the aqueous 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 R1 comprises glycerin, water and various remainders from glycerin and water; (c) recycling at least a part of the residual phase R2 in step (a); wherein i) from a glycerin phase G2 comprising remainders that differ from glycerin and water, at least one of said remainders is separated and the thus obtained, purified glycerin phase G2 is immediately supplied to the acrolein reaction region, or ii) at least one remainder different from glycerin and water is separated out of a mixture phase M1 obtained by mixing a glycerin phase G2 with the acrolein-poor residual phase R1, and the thus obtained, purified mixture phase M1 is supplied to the acrolein reaction region. The invention furthermore relates 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 glycerin phase.
    • 本发明涉及一种制备丙烯醛的方法,包括以下步骤:(a)在丙烯醛反应区中脱水甘油相G1,得到丙烯醛水溶液反应相; (b)将丙烯醛水溶液反应相至少部分分离为富含丙烯醛的丙烯醛相和不饱和丙烯醛(与丙烯醛相相比)残留相R1,其中残余相R1包含甘油,水和各种来自甘油的残余物 和水; (c)在步骤(a)中回收至少一部分残留相R2; 其中i)从包含不同于甘油和水的残余物的甘油相G2中分离出至少一个所述残余物,并将所得到的纯化甘油相G2立即供应到丙烯醛反应区,或ii)至少一个剩余部分 与甘油不同,水从丙三醇相G2和丙烯醛残留相R1混合得到的混合相M1中分离,将得到的纯化混合物相M1供给丙烯醛反应区。 本发明还涉及一种制备丙烯酸,吸水聚合物结构,化合物和卫生制品的方法,用于实施该方法及其应用的装置,用于纯化甘油相的方法和应用甘油相 。

    • The invention relates to a method for producing acrolein by dehydrating an aqueous glycerin phase in an acrolein reaction region, obtaining an aqueous acrolein reaction phase; at least partially separating the aqueous acrolein reaction phase into an acrolein-rich acrolein phase and an acrolein-poor residual phase comprising glycerin, water and various other residuals; and recirculating at least part of the residual phase into the acrolein reaction region. Additionally, removing at least one of the residuals, other than glycerin or water, from either of the glycerin phase or a mixture phase obtained by mixing the glycerol phase with the low-acrolein residue phase and feeding the resulting purified glycerin or mixture phase into the acrolein reaction region. The invention furthermore relates to a method for producing acrylic acid, water-absorbing polymer formations, compounds and hygiene articles, and to devices for carrying out those methods.
    • 本发明涉及通过在丙烯醛反应区域中脱水甘油三酯相来制备丙烯醛的方法,获得丙烯醛水溶液反应相; 至少部分地将丙烯醛水溶液反应相分离成富含丙烯醛的丙烯醛相和不含丙烯醛的残余相,其包含甘油,水和各种其它残余物; 并将至少部分剩余相再循环到丙烯醛反应区中。 此外,从甘油相或通过将甘油相与低丙烯醛残基相混合而获得的甘油相或混合相中除去甘油或水以外的至少一种残余物,并将得到的纯化甘油或混合物相加入到 丙烯醛反应区。 本发明还涉及制备丙烯酸,吸水聚合物结构,化合物和卫生制品的方法以及用于实施这些方法的装置。
