Reppe Process

Name:
Reppe Process
Detailed information:
Any of several processes involving reaction of acetylene (1) with formaldehyde to produce 2-butyne-1,4-diol which can be converted to butadiene; (2) with formaldehyde under different conditions to produce propargyl alcohol and, from this, allyl alcohol; (3) with hydrogen cyanide to yield acrylonitrile; (4) with alcohols to give vinyl ethers; (5) with amines or phenols to give vinyl derivatives; (6) with carbon monoxide and alcohols to give esters of acrylic acid; (7) by polymerization to produce cyclooctatetraene; and (8) with phenols to make resins. The use of catalysts, pressures up to 30 atm, and special techniques to avoid or contain explosions are important factors in these processes.See Acetylene.
