In the secon f stage of he process the said moiybdute, 0itungsta 'ze', then-reducvcL at m high temps ature (my (mt from 1200' to 1500 centijrgxde) by means of carbon, so that alkali metal is driven 0i? with mroon muzmxid, and these iso can be coiiected 0iutilized, in anjfideliked may. Metallic moiybdcnmn, or tungsten, remains in the VQSSBI and this can then be again utilized for treatment of a fresh charge the chiorid 0f the alkali metal with vapor of Water.

not limited thereto as any other suitable or convenient apparatus may be employed.

Aslexamplcs of the utilization of the gaseous products, I mention the absorption of the hydrochloric acid by .Water to produce ordinaryliquid hydrochloric acid, and the collection of the hydrogen in a gas holder and the passing of the mixtureof the vapor of the alkali metal and carbon monoxid into a condenser to condense' the alkali metal, or the burning of the gaseous mixture with the necessary access of air to form carbonate of the alkali metal, which may be allowed to deposit in a flue, or be otherwise collected.

If desired, the gases containing the vapor of alkali metal can be used for the productogether with nitrogen into an apparatus charged with carbon and heated to a high temperature and suitable for the synthetic retort, already referred to' for producing In this case a sufficiently large charge of carbon is passed into the said retort to form the cyanid in the, presence of v nitrogen, the requisite amount of nitrogen being passed into: the said retort either through the pipe which is otherwise used for passing the water vapor into the retort, or if preferred a second pipe may be provided for the nitrogen.

Although tungsten is referred to throughout the claims, it is to be understood that molybdenumniay be substituted therefor in place of tungsten.

What I claim is 1. The process of treatin alkali-metal chloride, which consists in su jecting alkali metal chlorid at a high temperature to the action of aqueous vapor in the presence of an intermediate metal of the chromium series, subsequently reacting on the resulting product at a high temperature with carbon .to obtain the intermediate metal and reusing the intermediate metal so obtained for the treatment of a fresh charge of alkalimetal chlorid.

2. The process of treating alkali -metal Or I may use the" carbon to obtain the tungsten and re-usi'ng the tungsten so: obtained for the'treatment of a fresh charge of alkali-metal chlorid.

3. The; process of: treating alkali-metal ehlorids, which consists in subjecting alkalimetal chlorid at a high temperature to the action of aqueous vapor in the presenceof timgste'n'in a finely divided condition, subsequently reacting on the residue at a'high I temperature with carbon'to obtain thejtuiigsten and re-using the tungsten 'so obtained for the treatment of a fresh charge of alkalimetal chlorid.

4. The herein described cyclic process of treating alkali-metal chlorids, which consists in first subjecting an alkali-metal chlorid at a high temperature to the action of aqueous vapor in the presence of tungsten, and-subsequently reacting on the tungsten of the alkali-metal so obtained with carbon to produce metallic tungsten and alkali-metal, the said tungsten being then re-used for treating a fresh charge of alkali metal chlorid". 5. The treatment of alkali-metal chlorid.

in a cyclic process of two stages, the first stage consisting in subjecting alkali-metal chlorid at a high temperature to the action I of aqueous vapor in the presence of'tungsten in a finely divided condition until substantially all the hydrogen and hydro-- chloric acid are revolved, and the second stage consisting in reacting on the residue at a high temperature with carbon to obtain the tungsten, the tungsten so obtained being thenre-used for the treatment of a fresh charge of alkali-metal chlorid.

In testimony whereof I have signed my name to this specification inthe presence'of two subscribing ,witnesses. I
