Abstract
The present disclosure provides for a method for measuring the concentration of one or more components in the reactor or a separation unit of an acetic acid process by both infrared and Raman spectroscopic analyses. In some embodiments, the conditions in the reactor or in any subsequent step of the acetic acid production process are adjusted in response to the measured concentration of one or more components.
