Detection of the total ester contents of TMPTA, TPGDA, and HDDA
Thread Content
I work for a coating company, where I am currently involved in UV paint production. I haven’t had much experience with the analysis and testing of esters before; however, after doing some research online, I now have a basic understanding of how to test such materials. Online, it is stated that the testing of esters like TMPTA, TPGDA, HDDA, methyl hydroxypropyl ester, and methyl hydroxyethyl ester is usually carried out using GC. I would like to ask the experts here: can the total ester content of these esters be determined through titration methods, such as saponification followed by back-titration to determine the alkali content? Has any teacher conducted analysis and testing of this kind? Could you offer some advice?
**How are standards or industry standards established? If there is a standard method for this purpose, or if the product standards specify an analytical method, it must be followed. If no quality control is applied to the analysis results by company W, the method can be chosen freely, provided that it is reliable and feasible, as well as sufficiently representative.
Regarding this standard, the only version available online at the moment is HB/FG03-2009; however, the implementation date is not specified, so its reliability cannot be determined for now.
