METHOD FOR THE PURCHASE OF A WATER-INSOLUBLE ORGANIC NITROGEN BASE, FROM WATER-SOLUBLE HYDROCHLORHYDRATE OF THIS BASE AND A METHOD FOR THE FABRICATION OF SODIUM BICARBONATE.

摘要

1. Process for the production of a water-insoluble nitrogenous organic base, starting from a water-soluble hydrochloride of the said base, according to which the hydrochloride is treated with water and a basic agent capable of decomposing it, to form an organic phase including the nitrogenous organic base and an aqueous phase capable of being separated from the organic phase be gravity separation, and the organic phase is collected, characterized in that use is made of a quantity of basic agent which is deficient relative to that required to decompose all of the hydrochloride, and the aqueous phase is treated with a complement of basic agent.
