| description | The present invention relates to a technique for producing the acrylic acid, which at least comprises the following procedures: a. dewatering the glycerol and the dehydration product containing the acrolein; b. gas-phase oxidation of the dehydration product and the monomer gas containing the acrylic acid; c. contacting the monomer gas with the quenching object and the quenching phase containing the acrylic acid is obtained; d. manufacturing the quenching phase and the monomer phase containing the acrylic acid is obtained. The present invention also relates to a technique for preparing the polyalcohol with the acrylic acid free radical polymerization, preferably preparing the water-absorbing polymer which is obtained by the technique and includes the water-absorbing polymer of the acrylic acid with at least 25wt% part neutralized, a complex, a technique for producing the complex, an application of the acrylic acid which is obtained by the technique in preparing the water-absorbing polymer structure, a device f |
