Abstract
A distillation-reaction apparatus comprises at least one distillation-reaction zone (G,H) having, on a perforated support (5) permitting the passage of fluids at least one element of type J--container (3b) of volume Vt containing a volume Va of solid catalytic particles--and at least one element of type K--(4) of type K1 and/or (3a) of type K2--the element of type K2 being a container not containing solid catalytic particles, the elements having adequate mechanical characteristics to withstand the loading of the elements in the zone and the perforations of the support being sufficiently small to retain the said elements. The apparatus can be used for performing chemical reactions and the fractionation of the reaction mixture, e.g., for the synthesis of ethers from olefins and alcohols.
