| 摘要 |
The present invention relates to a device (1) for producing acrylic acid, comprising a first reactor (2) and at least one other reactor (3), at least the first reactor (2) being a tubular reactor with a plurality of tubes (4) that enclose a catalyst that catalyzes the synthesis of acrolein, with the tubes (4) discharging into a collecting chamber (6), which can be connected for fluid flow through a discharge area (7) to the at least one other reactor (3), with the discharge area (7) comprising means of smoothing flow (8), which bring about a laminar flow profile of a gas flowing through the discharge area (8). The invention also relates to a method for producing acrylic acid, an acrylic acid, a method for producing a hydrophilic polymer, a hydrophilic polymer, a method for producing a water-absorbing hygiene article, chemical products such as fibers, molded objects or films, and to the use of an acrylic acid. |
