Abstract
This invention provides a dispensing assembly which is adapted to deliver two separate instantaneously coreactive liquid streams into an external contacting zone. The two reactants do not make contact within the body of the dispensing assembly, which prevents solid product formation and clogging within the dispensing assembly nozzles. The dispensing assembly is suitable for the coreaction of liquid carbon dioxide and liquid ammonia to produce free-flowing ammonium carbamate powder having a purity of substantially 100 percent.
