Leblanc-process Sentence Examples
The term alkali is employed in a technical sense for the carbonate and hydrate (of sodium), but since in the Leblanc process the manufacture of sodium sulphate necessarily precedes that of the carbonate, we include this as well as the manufacture of hydrochloric acid which is inseparable from it.
THE Leblanc Process The Leblanc process, which was invented by Nicolas Leblanc about 1790, begins with the decomposition of sodium chloride by sulphuric acid, by, which sodium sulphate and hydrochloric acid are produced.
From that time onward the Leblanc process spread more and more, and for a considerable period nearly all the alkali of commerce was made by it.

THE Ammonia-Soda Process In spite of the great improvements effected during recent times the Leblanc process cannot economically compete with the ammonia-soda process, principally for two reasons.
