Claim 1
Independent Claim
110 words
IN A PROCESS FOR THE PRODUCTION OF OXYGENATED ORGANIC COMPOUNDS BY THE VAPOR PHASE PARTIAL OXIDATION OF HYDROCARBONS SELECTED FROM THE GROUP CONSISTING OF PROPANE AND BUTANE WITH AN OXYGEN CONTAINING GAS, THE STEPS WHICH COMPRISE DECOMPOSING THE PEROXIDES IN THE HOT REACTION GASES PRODUCED DURING THE PARTIAL OXIDATION, COOLING THE HOT REACTION GASES WHICH ARE AT A TEMPERATURE OF BETWEEN ABOUT 800 AND 900*F. TO THE TEMPERATURE OF ABOUT 500*F. BY HEAT TRANSFER TO A SOLID IN AN INTERVAL OF NOT MORE THAN 0.7 SECONDS WHILE RECOVERING THE HEAT FROM SAID GASES IN USEFUL FORM, AND QUENCHING THE PARTIALLY COOLED REACTION GASES BY DIRECT CONTACT WITH A LIQUID MEDIUM.
