The purpose of this study is to address the problem of discharge of distiller waste from Solvay process, and at the same time, to realize the production of soda ash from Glauber’s salt — natural ores containing sodium sulfate, or industrial byproduct sodium sulfate. Half-saturated and near-saturated brines were prepared by reacting simulated distiller wastes — aqueous solutions containing calcium chloride and sodium chloride, with sodium sulfate. Experimental results show that the dissolution of sodium sulfate controls the reaction rate and the final composition of the brines. Temperature plays a key role in promoting the dissolution of sodium sulfate therefore to the reaction result, especially to the preparation of near-saturated brine. With equivalent sodium sulfate, more than 90 percent of the Ca2+can be deleted. The precipitate (gypsum or anhydrite) can be used to produce cement or other construction materials.

As a contribution to the chemistry of muscle tissue, the solubility of the protein of haddock muscle in aqueous solutions of sodium chloride and neutral potassium phosphate, respectively, was determined. The results are expressed in tabular form and graphically in the form of solubility curves. A water-soluble protein and also a salt-soluble protein were isolated from dialyzed haddock muscle by extraction methods. These proteins were obtained in a comparatively pure condition by precipitation from solution in the region of their isoelectric points.

Direct Condensation

Powdered polychloroprene rubber (PCR-244) was prepared by the direct condensation, and the influence of agglomerator kinds and dosages on powdering of PCR-244 were investigated, including trivalent salt (aluminum chloride), divalent salt (magnesium sulfate, calcium chloride) and monovalent salt (sodium chloride, potassium chloride). The result showed that powder chloroprene rubber could be used as adhesive material that calcium chloride was used as agglomerator.
