Malonic acid is a precursor to specialty polyesters. It can be converted into 1,3-propanediol for use in polyesters and polymers (whose usefulness is unclear though). It can also be a component in alkyd resins, which are used in a number of coatings applications for protecting against damage caused by UV light, oxidation, and corrosion. One application of malonic acid is in the coatings industry as a crosslinker for low-temperature cure powder coatings, which are becoming increas…

WebJul 3, 2024 · Dimethyl malonate is a good nucleophile on account of the two ester groups on either side of the central carbon atom. It has a p K a of 12.9, which is extremely acidic for a C − H bond. The first step is a Michael addition. The resultant enolate will equilibrate, enabling it to form a much more stable 6 membered ring. http://www.isaacpub.org/images/PaperPDF/MOCR_100008_2016122909371456170.pdf townhomes for sale outside of philadelphia
