Acrylic acid, water-absorbent polymer structures based on renewable resources and method for producing said structures |
摘要 |
The present invention relates to a process for production of acrylic acid, comprising at least the following steps: a. dehydrating glycerine to a dehydration product comprising acrolein; b. gas phase oxidation of the dehydration product comprising acrolein to obtain a monomer gas comprising an acrylic acid; c. bringing into contact the monomer gas with a quench means to obtain a quench phase comprising acrylic acid; and d. processing the quench phase comprising acrylic acid to obtain a monomer phase comprising acrylic acid. The present invention may also relate to a process for preparation of polymers by radical polymerization of acrylic acid, the water-absorbing polymers obtainable by this process, water-absorbing polymers based to at least 25 wt % upon partially neutralized acrylic acid, a composite, a device for preparation of acrylic acid, a process for preparation of acrylic acid, and the acrylic acid obtainable by this process. |
