3802. VERIN FÜR CHEMISCHE INDUSTRIE A. G. [Effecting Reactions Between Gases.] Swiss Patent 127,243, May 27, 1926. Chem. Abs., vol. 23, 1929, p. 1188.

Reaction between gases are effected by supplying 1 of the reagents to each side of a porous wall, the gases meeting and reacting in the pores of the wall. Suitable apparatus comprises a porous tube arranged within an impermeable tube, connections being provided for passing gases, preferably in countercurrent, through the porous tube and through the annular space between the tubes. The porous tube may be impregnated with a catalyst. Examples describe the preparation of (1) CH4 from CO and H₂O; (2) MeOH from CO and H₂O; (3) MeOH from HCOOH and H₂; (4) MeOH from HCOOMe and H₂; (5) Ac₂O from ethylidene diacetate and air; (6) AcOH from CH₃CHO and air; (7) SO₂Cl₂ from SO2 and Cl.
