A METHOD FOR FORMING CHLORINE HYDRATE WHICH COMPRISES VAPORIZING AQUEOUS ZINC CHLORIDE SOLUTION HAVING A CONCENTRATION GREATER THAN 10 PERCENT ZINC CHLORIDE WITH 0.1 TO 4 VOLUMES OF CHLORINE DISSOLVED AND/OR DISPERSED THEREIN TO FORM A GASEOUS FORM OF WATER AND CHLORINE AND CONTACTING SAID MIXTURE OF GASES WITH A HEAT TRANSFER MEANS AT A TEMPERATURE BETWEEN ABOUT -50* TO ABOUT +9*C TO CONVERT THE GAS MIXTURE TO CHLORINE HYDRATE IN SOLID FORM THE MOLAR RATIO OF WATER AND CHLORINE IN GASEOUS FORM CONTACTING THE HEAT TRANSFER MEANS BEING FROM ABOUT 0.01 TO ABOUT 8:1 AND FURTHER PROVIDING THAT
Claim 3
Dependent Claim
87 words
A method according to claim 1, wherein gaseous chlorine, released from aqueous zinc chloride, is continuously fed into a hydrate-forming zone, water vapor is continuously formed by vaporization of the liquid water, chlorine hydrate is continuously formed, the feed of chlorine and the vaporization of water are regulated to maintain a molar ratio of about 1:1 and the temperature of the heat transfer means, said heat transfer means and the feed of chlorine and vaporization of water are increased or decreased together to maintain said molar ratio.
Claim 4
Dependent Claim
92 words
A method according to claim 1, wherein both the gaseous chlorine and the liquid water utilizied are obtained from an aqueous metal chloride solution in which the gaseous chlorine is at least partially dissolved and/or dispersed, vaporization of the liquid water to gaseous form is effected by heating it, the proportions of water and chlorine gas contacting the heat transfer means are maintained at a molar ratio of about 0.01:1 to 12:1, and the heat transfer means is a refrigerating means having a refrigerant which has a temperature from -30* to +9*C.
Claim 5
Dependent Claim
96 words
A method as defined in claim 1, wherein gaseous chlorine, released from aqueous zinc chloride, is continuously fed into a hydrate-forming zone, water, in liquid form, is continuously fed into saiD zone, water vapor or gas is continuously formed by vaporization of the liquid water, chlorine hydrate is continuously formed, the feed of chlorine and the vaporization of water are regulated to maintain a molar ratio of about 1:1, and the heat removed by the refrigerating means and the feed of chlorine and vaporization of water being increased or decreased together to maintain said molar ratio.
Claim 6
Dependent Claim
24 words
The method of claim 1, wherein the concentration of zinc chloride ranges from above 10 percent by weight to about 35 percent by weight.
Claim 7
Dependent Claim
62 words
The method of claim 1, wherein the gaseous chlorine and water are obtained from an aqueous zinc chloride solution of a concentration of greater than 10 percent zinc chloride, with 0.1 to 4 volumes of chlorine dissolved and/or dispersed therein and the molar ratio of water and chlorine in gaseous form contacting the heat transfer means is from about 0.01 to 8:1.
