- W1978623797 abstract "Chemists, although all acknowledging the existence of an intimate relation between the vegetable alkaloids and ammonia, are nevertheless divided in their opinions respecting the nature of this connection, two theories having been propounded upon the subject. According to the one, that of Berzelius, the bases would have to be considered as conjugated ammonias in which ammonia still pre-exists as such; while according to Liebig’s views, these substances are represented as amides, i.e . as ammonia in which one equivalent of hydrogen is eliminated and replaced by an equivalent of a compound radical. The researches of the author prove that the theory of Berzelius is inadmissible, at all events for the volatile organic bases, inasmuch as in these substances ammonia ceases to exist as such. They show, moreover, that Liebig’s view, although correctly expressing the constitution of by far the greater number of the volatile bases known, and presenting, when considered at the time it was first propounded, a wonderful anticipation of subsequent discovery, represents nevertheless only a special case of a much more general relation. The result at which the author has arrived is, that ammonia is capable of losing either 1 (Liebig's case) or 2 or S equivs. of hydrogen which are respectively replaced by 1, 2 or 3 equivs. of the same, or various compound radicals, a variety of substances apparently endless being produced, in which its fundamental property (the basic character) is retained, although modified by the number of radicals introduced and their position in the scale of organic compunds ." @default.
