Claim 1
Independent Claim
87 words
A PROCESS FOR PRODUCING NITROHYDROCARBONS WHICH COMPRISES CONTACTING ATOMIZED NITRIC ACID AND A MOLAR EXCESS OF A HYDROCARBON CONTAINING FROM ABOUT 1 TO 10 CARBON ATOMS IN THE GASEOUS PHANE IN A REACTION ZONE UNDER NITRATION CONDITIONS INCLUDING SUPERATMOSPHERIC PRESSURE, A TEMPERATURE OF AT LEAST 300*C. AND SUFFICIENT TO NITRATE THE HYDROCARBON BUT INSUFFICIENT TO DECOMPOSE THE NITROHYDROCARBON, AND A RESIDENCE TIME SUFFICIENT TO NITRATE THE HYDROCARBON AND UP TO ABOUT 300 MILISECONDS, AND IMMEDIATELY QUENCHING THE RESULTANT REACTION PRODUCTS TO FREEZE THE EQUILIBRIUM OF THE REACTION.
