Monoethanolamine Raw Material Testing Procedure
Monoethanolamine (MEA) is a colorless liquid used as a cleaning agent and chemical intermediate in various industries. Monoethanolamine Raw Material Testing Procedure its purity and quality, the following analytical methods can be used:
pH measurement: Monoethanolamine has a basic pH due to its amine functional group. The pH of a sample can be measured using a pH meter or indicator paper.
Titration: This method involves slowly adding a standard acid solution to a sample of MEA until the solution reaches its equivalence point, indicated by a change in pH or color. The volume of acid required to reach the equivalence point can be used to determine the concentration of MEA in the sample.
Gas chromatography (GC): This method separates and quantifies the components of a sample using a gas ...
