The use of Infrared Spectroscopy for online control of processes and to detect the termination thereof

摘要

Analytical method for Measuring the concentration of a substrate acid n - (PHOSPHONOMETHYL) imindiacu00e9tico (npmida '' ''), a product of N - (PHOSPHONOMETHYL) glycine, formaldehyde, acid fu00f3rmido, n-methyl-n - (PHOSPHONOMETHYL Glycine (NMG) '' '') acid, n-methyl - (aminometilfosfu00f3nico Mampa) or aminometilfosfu00f3n acid ICO (AMPA '' '') in an aqueous mixture of same, using infrared spectroscopy.It also relates to a process for oxidizing acid substrate N - (PHOSPHONOMETHYL) imindiacu00e9tico to form a product N - (PHOSPHONOMETHYL glycine) and, as part of the process, Measuring the concentration of at least one reactant, product or by-product of the oxidation reaction using the methods DO Analytical and control the process of oxidation in response to the Measurement taken.
