Piezochemie kondensierter Systeme


THE direction and extent of a physical or chemical change are frequently determined or modified by pressure. This fact has long been inown, and has been the subject of occasional investigation at various times, even from the oearliest periods of systematic scientific inquiry. It occupied the attention of the first Italian academies, and was among the matters experimentally studied by the Fellows during the early years of the Royal Society. Until comparatively Decent times, however, work on the subject was sporadic, intermittent, and directed mainly to the investigation of particular cases rather than to the elucidation of general principles. The necessities of modern chemical manufactures have ocreated a demand for further and more accurate knowledge, inasmuch as the whole course of a ochemical reaction and its economic aspect may odepend upon it. Many instances of this fact might be cited. One of the most recent, and also oone of the most striking, is seen in the case of the synthetic production of ammonia from its oelements under the influence of catalysts, in which the question of the appropriate pressure is of fundamental importance.
