ABSTRACT:
High purity ammonia is quantitatively produced from urea by reaction with water in the presence of acid. A major advantage of the invention is that urea can be safely transported to a conversion site, then converted to ammonia. The net result is that high purity ammonia is available wherever it is needed without the toxic hazard presented by transporting ammonia.
