III. On the union of ammonia nitrate with ammonia

Abstract Ammonia nitrate deliquesces in ammonia gas at ordinary temperatures and pressures, forming a solution of the salt in liquefied ammonia. To prepare the product, it is only requisite to pass dry ammonia gas into a flask containing the dry nitrate; but the condensation proceeds more rapidly if the flask is surrounded with ice. The liquid obtained varies in composition according to the temperature and pressure. At a temperature of 23° and the pressure of the atmosphere, it consists of about four parts of nitrate to one of ammonia by weight; but under greater pressure, or at lower temperatures, much more ammonia can be condensed by the nitrate.
