Process for the preparation of (meth) acrylic acid and (meth) acrylic acid esters |
| abstract |
Process for the preparation of (meth) acrylic acid, comprising DOLLAR A (a) the preparation of a reaction gas mixture by catalytic gas phase partial oxidation of suitable C¶3¶ or C¶4¶ precursors, DOLLAR A (b) absorption of the reaction gas mixture from (a) in at least one absorbent with an absorbent, desorption of the loaded absorbent in at least one desorbent by treatment with a stripping gas and DOLLAR A (c) subsequent rectificative purification of the absorbent to obtain crude (meth) acrylic acid, wherein DOLLAR A - the at least one absorbent with Absorbent quantity is operated from 15 to 20 kg per m · 3 · reaction gas mixture, DOLLAR A - the temperature of the inlet to the desorption apparatus is from 120 to 140 ° C and DOLLAR A - the stripping gas quantity in the desorption apparatus is more than 4 m · 3 · per m · 3 · Reaction gas mixture is. |
