Method of producing low volatility amines for power plant pH control by in situ hydrolytic decomposition of a more volatile amine with a ring structure

摘要

A method of producing low volatility amines for power plant pH control by in-situ hydrolytic decomposition of a more volatile amine with a ring structure. A ring amine having a certain molecular weight and a volatility is introduced into the pressurized water reactor. The ring amine undergoes at least partial in-situ hydrolytic decomposition to produce at least one daughter amine. The daughter amine has a molecular weight equal to or greater than the ring amine and has a volatility less than the ring amine. The daughter amine, and the mixture of the daughter amine and the ring amine act to control the pH in the reactor. In an alternative embodiment, the ring amine undergoes complete decomposition to form at least one daughter amine, and the daughter amine(s) acts to control the pH in the reactor.
