Abstract
In this work, the main aim is focused on the decomposition products of film-forming amines which are used as corrosion protection of devices against surface corrosion at frequent short outages. Filming amines are a mixture of volatile alkaline and contact organic amines, which protect both the water and the steam environment. It was confirmed, the organic matter is not stable at high temperature and decomposes to organic acids with short chain (acetic, formic) which decrease pH value and increase conductivity value.
