Reaction Mechanism of Amine and Epoxy For a more detailed discussion of the epoxy-amine reaction chemistry, visit a previous post called Epoxy Cure Chemistry Part 4: … This document provides a procedure for determining the epoxide equivalent of epoxy resins and the amine value of polyamide resins. Theoretical Analysis of Factors Affecting the Property of Aliphatic Amines Compared to the noncyclic alkane molecules, aliphatic amine molecules have the following … The calculation is based on the pK values of the amino acids and of the terminal amine & carboxyl group of the peptide chain. of pure MDI = 4,200 ÷ 33. B[Amine Value] as given in the calculation should be used. The amine solution solvent must also be “blanked”. The firs … Most epoxy resin coatings designed for ambient application employ polyfunctional amines as the curing agent, either alone or in some cases in combination with other curing agents. Naresh on pharmaceutical analysis, focusing on the determination of acid value, saponification value, and … We would like to show you a description here but the site won’t allow us. This section first details the calculation for principles of theoretical and practical minimum energy requirements given process temperatures and feedstocks. There is more to isoelectric point than just the calculation of pI values for individual amino acids! The same concepts also apply to peptides and … Total amine Apparent equivalent weight can be deterrnined by titration with hydrochloric acid using a bromocresol green indicator. If the original amine sample is a solution, then G must be multiplied by the mass fraction of amine in the solution to get an accurate EW. By understanding the … Methods may include quantifying the concentration of residual free amine and/or free carboxylic acid in a product mixture prepared from a reaction of a … The theoretical yield is a term used in chemistry to describe the maximum amount of product that you expect a chemical reaction could create.
