Synthesis, film-forming properties, and thermal and light sensitivity of N,N’-bis[4-hydroxy(alkoxy, acyloxy)-3-alkoxyphenylmethylidene]benzene-1,4-diamines was written by Dikusar, E. A.;Kozlov, N. G.;Potkin, V. I.;Azarko, V. A.;Yuvchenko, A. P.. And the article was included in Russian Journal of General Chemistry in 2008.Quality Control of 4-Formyl-2-methoxyphenyl isobutyrate This article mentions the following:
Previously unknown E,E-isomeric Schiff bases were synthesized by reaction of p-phenylenediamine with 4-hydroxy-3-methoxybenzaldehyde, 3-ethoxy-4-hydroxybenzaldehyde, and their O-alkyl and O-acyl derivatives in anhydrous methanol. Film-forming properties and thermal and light sensitivity of the products were studied. In the experiment, the researchers used many compounds, for example, 4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4Quality Control of 4-Formyl-2-methoxyphenyl isobutyrate).
4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Quality Control of 4-Formyl-2-methoxyphenyl isobutyrate
