Abstract

Abstract A chemical reactor comprising a generally cylindrical reaction vessel, a series of three jackets defining a central chamber and three annular chambers within the reactor, means for feeding a first gaseous reactant, such as chlorine, to the lower portion of the first annular chamber to displace liquid reaction medium therein to the centrally disposed chamber for flow downwardly therethrough, means for introducing a second gaseous reactant, such as an ethylenic hydrocarbon, to the third annular chamber to cause flow of the liquid reaction medium therein upwardly therethrough to the second annular chamber for reaction with the reaction product of the chlorine and water in the liquid reaction medium to thereby minimize the production of chlorinated alkanes.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 30 words
A reactor as defined in claim 1 wherein the means for introducing the first gaseous reactant to the first annular chamber includes a plurality of diffusers spaced about the chamber.
Claim 2
Dependent Claim 38 words
A reactor as defined in claim 1 wherein the third jacket is formed at its upper portion in an inwardly extending lip to minimize the turbulence of liquid from the second annular chamber to the third annular chamber.
Claim 3
Dependent Claim 36 words
A reactor as defined in claim 1 which includes a counter-current washing column on the upper portion of the frusto-conical portion and means to add liquid to the column to wash gases from the frusto-conical portion.
Claim 4
Dependent Claim 21 words
A reactor as defined in claim 1 wherein each of the jackets are substantially cylindrical and coaxial each with the other.
