Abstract
Abstract An apparatus and process for controlling the direct reaction of chlorine with a saturated hydrocarbon wherein the hydrocarbon and the chlorine are premixed in the dark under nonreacting conditions, the hydrocarbon-chlorine mixture is dispersed as globules or droplets in a flowing aqueous medium, and the aqueous medium carrying the suspended globules is exposed to reactioninitiating light, wherein the reaction temperature is controlled by the aqueous phase and inorganic reaction products are removed into the aqueous phase along with any water soluble inhibiting agents to permit complete reaction of the chlorine with the hydrocarbons are disclosed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
145 words
AN APPARATUS FOR CHLORINATING HYDROCARBONS AND THE LIKE COMPRISING: A VERTICAL ELONGATED REACTION VESSEL, AT LEAST A PORTION OF THE WALL THEREON BEING TRANSPARENT TO REACTION-INTIATING LIGHT, WATER INLET MEANS PROXIMATE THE BOTTOM OF SAID REACTION VESSEL, WATER AND HYDROCHLORIC ACID OUTLET MEANS BELOW THE TOP OF SAID REACTION VESSEL; A MIXING VESSEL HAVING CHLORINE INLET MEANS AND HYDROCARBON FEED INLET MEANS FOR PREMIXING CHLORINE AND HYDROCARBON REACTANTS, IN THE ABSENCE OF LIGHT, TO FORM A HOMOGENEOUS MIXTURE OF REACTANTS; CONDUIT MEANS TO PASS THE PREMIXED REACTANTS TO A GLOBULE FORMING MEANS, SAID GLOBULE FORMING MEANS BEING IN AND PROXIMATE THE LOWER PORTION OF SAID REACTION VESSEL TO DISPERSE GLOBLES OF REACTANT SUPENDED IN UPWARD FLOWING WATER; ILLUMINATING MEANS FOR EXPOSING THE REACTION VESSEL CONTENTS TO REACTION-INITIATING LIGHT, AND MEANS ABOVE THE WATER AND HYDROCHLORIC ACID OUTLET MEANS FOR REMOVING AN ORGANIC REACTION PRODUCT PHASE.

Claim 3
Dependent Claim
45 words
The apparatus of claim 1 further comprising: conduit means for carrying the components of the organic reaction product phase to a separator means; means for separating said components of the organic phase; and means for returning unreacted organic feed material to the premixing vessel means.
Claim 4
Dependent Claim
74 words
The apparatus of claim 1 further comprising: conduit means to recirculate the aqueous phase from said reaction vessel; heat exchanger means in line with said recirculating conduit means for controLling the temperature of the recirculating aqueous phase; outlet and valve means in the recirculating conduit means for removal of muriatic acid; and valve and inlet means in the recirculating conduit means to add water to maintain the aqueous fluid level in the reaction vessel.
