Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
A METHOD OF PREPARING OXIDATION PRODUCTS OF HYDROCARBONS WHICH COMPRISES REACTING A GASEOUS MIXTURE OF AN ALIPHATIC HYDROCARBON CONTAINING FROM 3 TO 6 CARBON ATOMS PER MOLECULE WITH A FREE OXYGEN-CONTAINING GAS IN APPROXIMATELY EQUIMOLAR PROPORTIONS OF HYDROCARBON TO OXYGEN IN AN ELONGATED REACTION ZONE WHEREIN THE MIXTURE IS MAINTAINED AT A PRESSURE OF ABOUT ONE ATMOSPHERE, A REACTION ZONE TEMPERATURE OF FROM ABOUT 500* F. TO ABOUT 800* F. AND A SUBSTANTILLY CONSTANT LINEAR VELOCITY OF ABOUT 10 CM. PER SECOND TO PRODUCE A SINGLE, STABLE BLUE LUMINESCENT ZONE WITHIN THE REACTION ZONE AND WITHDRAWING THE RESULTING OXIDATION PRODUCTS DOWNSTREAM FROM THE LUMINESCENT ZONE.
Claim 2
Independent Claim

A METHOD OF PREPARING OXIDATION PRODUCTS OF HYDROCARBONS WHICH COMPRISES REACTING A GASEOUS MIXTURE OF AN ALIPHATIC HYDROCARBON CONTAINING FROM 3 TO 6 CARBON ATOMS PER MOLECULE WITH A FREE OXYGEN-CONTAINING GAS IN APPROXIMATELY EQUIMOLAR PROPORTIONS OF HYDROCARBON TO OXYGEN IN AN ELONGATED REACTION ZONE WHEREIN THE MIXTURE IS MAINTAINED AT A PRESSURE OF ABOUT ONE ATMOSPHERE, A REACTION ZONE TEMPERATURE OF FROM ABOUT 500* F. TO ABOUT 800* F. AND A SUBSTANTILLY CONSTANT LINEAR VELOCITY OF ABOUT 10 CM. PER SECOND TO PRODUCE A SINGLE, STABLE BLUE LUMINESCENT ZONE WITHIN THE REACTION ZONE AND WITHDRAWING THE RESULTING OXIDATION PRODUCTS DOWNSTREAM FROM THE LUMINESCENT ZONE.
Claim 3
Dependent Claim
101 words
A PROCESS OF PRODUCING ACETYLENE WHICH COMPRISES PASSING A GASEOUS MIXTURE OF AN ALIPHATIC HYDROCARBON CONTAINING FROM 2 TO 12 CARBON ATOMS PER MOLECULE AND A FREE OXYGEN-CONTAINING GAS THROUGH AN ELONGATED REACTION ZONE MAINTAINED AT A PRESSURE OF FROM ABOUT 200 TO ABOUT 1,000 MM. HG AND AT A TEMPERATURE OF FROM ABOUT 400 TO ABOUT 1000* F. AT A SUBSTANTIALLY CONSTANT LINEAR VELOCITY IN EXCESS OF 2 CM. PER SECOND TO PRODUCE A SERIES OF AT LEAST TWO BLUE LUMINESCENT ZONES WITHIN THE REACTION ZONE, WITHDRAWING THE RESULTING REACTION PRODUCT DOWNSTREAM FROM THE LUMINESCENT ZONES AND SEPARATING ACETYLENE THEREFROM.
Claim 4
