PLThe longest term of the patent until September 24, 1941. The present patent relates to the development of them, and without the release of water and in the process described in the patent No. 5926 in the molten state, they do not decompose - namely, the preparation of sulfur from sulfur into the calcareous sulphates. It turned out that the starting sulphates, dissolved in the molten lime stone, dissolve not only in sodium chloride by the addition of coke, molten sodium chloride, but also in the disintegration of the calcium sulphide. in other molten salts of alkali metals, according to the present invention, a different liquid and transparent solution is used for the melting of alkaline earth metals, as well as for fusing with the alkali sulphates of the latter, to give sodium chloride instead of sodium chloride. The alkali metal or alkaline earth salts are used, the alkali metal and calcium salts, or mixtures of these salts, as long as those which melt without giving off water and in the molten state do not act to decompose the calcium sulphates. Alkali metal sulfates as well as alkali metal and alkaline earth metal fluorides alone or in a mixture with other alkali and alkaline earth metal salts are particularly suitable. When fluspate is used as a flux, don is added to lowering the melting point of alkali fluorides or alkaline earth chlorides. The same result is achieved when fusing a mixture of fluorides: alkali metals or alkaline earth metals with alkaline earth sulphates, because the melting point of this mixture is much lower than the melting point of the individual components. This produces a liquid alloy of the alkaline earth sulphates and the salts of alkali metals and alkaline earth metals or a mixture of these salts and is further processed to obtain sulfur as described in Patent No. 5926. Coke is introduced into the alloy to reduce calcium sulphate into sulphide, and the latter, by blowing in steam or acid, turns into calcium sulphate or into the corresponding salt and hydrogen sulphide, which The salt is then converted in a known manner into sulfur or its compounds. With the use of alkali metal or alkaline earth salts which, individually or mixed together, cause acid release in the footsteps when blowing steam in, the resulting acid is successfully reduced after a definite reduction. The calcium sulfide is dissolved by the injection of steam into the calcium salt and the hydrogen sulfide, because in this case the calcium sulfide is affected by the nascend acid. PL
