Abstract
The hydrogen halide is produced by reacting a halogen with water in the presence of ruthenised and/or platinised titanium. The resulting hydrogen halide is preferably used to replenish hydrogen halide being electrolysed. In the reaction of the halogen with water, there is a rapid increase in acid concentration up to about 3%, then a slower increase up to a concentration of about 5%, the latter being a higher concentration than obtainable in prior art reaction of water with a halogen.
Description
1 GB 2 107 295 A 1
SPECIFICATION
Production of hydrogen halide The present invention is concerned with the production of hydrogen halide by reacting a 5 halogen with water.
The production of a hydrogen halide, such as hydrochloric acid, by reacting the appropriate halogen with water is known and is disclosed in, for example, U.S. Patents 129509, 1420209, 1485816,1695552,1843196,1843354, 1870308, 238896,3995016,4021323 and 4069120.
According to the present invention, there is provided a method of producing hydrogen halide by reacting a halogen with water, in which the reaction is carried out in the presence of ruthenised and/or platinised titanium.
In the method according to the invention, the halogen is preferably bubbled through a body of the water for reaction therewith.
The hydrogen halide produced according to the invention may be used to replenish hydrogen halide being electrolysed, for example, in the method described and claimed in U.K. Patent Application 7923161 (Specification 2026033), from which the present application has been divided.
In the following description, reference will be made to the accompanying drawings, in which:
Figure 1 is a graph of acid concentration against time in the method according to the invention; and Figure 2 is a schematic view illustrating an 85 example of the method according to the invention.
Figure 1 shows curves 1 and 2 which relate to the method according to the invention, using ruthenised titanium and platinised titanium, respectively, when these catalysts are used in the 90 method described in the above-mentioned U.K.
Patent Application, with reference to Figure 1 thereof.
The ruthenised titanium used was prepared by the well known method of air heating porous titanium dipped in a ruthenium chloride solution, while the platinised titanium used was prepared by the well known method of air heating porous titanium dipped in a chloroplatinic acid solution.
In curves 1 and 2, there is a rapid increase in the acid concentration in a solution containing 100 dissolved halogen below about 3% concentration, and then a very slow increase in concentration, until the concentration reaches about 5%, when hydrogenation of the halogen essentially stops. Even so, the 5% concentration is higher than the hydrogenation level obtainable in the prior art.
The method of producing hydrogen halide according to the present invention can be used as shown, for example, in Figure 2, for stripping a halogen from a gas stream, since the obtainable concentration of halogen in water is increased.
Referring to Figure 2, a tank 280 is partially filled with water from valved conduit 282. Ruthenised titanium and/or platinised titanium, in particle form, is introduced into the water through feed line 284. A gas stream, illustrated as chlorine, is directed by valved conduit 286 into a diffuser 290 at the lower portion of tank 280. As the halogen bubbles through the water in the presence of the catalyst, the halogen is converted to hydrohalic acid to higher concentrations than obtained by water itself. A drain 292 ultimately drains tank 280. By this arrangement, more chlorine can be stripped from a gas stream. Any insoluble gases pass from tank 280 by outlet 294.
