PENGUKURAN KONSTANTA DISOSIASI ASAM MONOETHANOLAMINE PADA SUHU 30-60°C
Abstract: Global warming
caused by greenhouse gas emissions, e.g. carbon dioxide (CO2), in the
atmosphere is now becoming a very serious problem facing the world community.
Carbon dioxide emission increase from year to year, thus a necessary effort to
reduce CO2 is required. Amine-based absorption is one of the methods for
post-combustion capture. Monoethanolamine (MEA) is commonly used for CO2
capture solvent. This study aims to measure protonation constant (pKa) of MEA
from 30 to 60°C using the potentiometric titration method. The results show
that the pKa values of MEA are in general agree with the literature data. For
instance, the pKa value of MEA at 30°C is 9.83 and that obtained from the literature
is 9.80. Comparison between those two values gives a deviation of 0.22%.
