1. A reactive stripping process for continuously carrying out chemical reactions while separating the reactants from at least one of the reaction products in a reactor column, the process comprising:

  • (a) allowing liquid reactants to flow concurrently and downwardly in a reactor column having a side wall and having;

    (i) a plurality of perforated trays provided therein, and(ii) a plurality of downcomers interconnecting the trays, a portion of each said downcomer, a portion of the side wall of the reactor column and one of the perforated trays in combination defining a chamber with a catalyst contained therein in order to form a liquid reaction mixture including at least a lower boiling reaction product, said reactor column additionally having, when the catalyst is other than a liquid catalyst, a first screen located on each tray and each of the downcomers having a second screen connected to the top thereof,(b) simultaneously allowing a nitrogen stream to pass upwardly through the trays and chambers for agitating the content of the chambers, wherein, when the catalyst is other than a liquid catalyst, a suspension of the catalyst is formed in the liquid reaction mixture,(c) withdrawing at least the lower boiling reaction product from an upper portion of the reactor column with the nitrogen stream, and(d) discharging the remainder of the reaction mixture from a lower portion of the reactor column.
