Uses In 1987, about 600 million lb of MDA was produced in the United States captively as a chemical intermediate; additional amounts were also imported. Approximately 99% of theMDAand polymericMDAproduced in the United States, usually by the acid-catalyzed reaction of aniline with formaldehyde, is used as a chemical intermediate in the closedsystem production of methylene diisocyanate (MDI) and polymeric MDI, which are used extensively in the manufacture of rigid semiflexible polyurethane foams for automobile safety cushioning, and also in the production of wire coatings. MDA is also used as a hardener or curing agent for epoxy resins (providing cross-linkages), in the manufacture of various natural and synthetic rubbers as an antioxidant, in the production of polyurethane elastomers, as a curing agent for neoprene, as an antioxidant in rubber, in the preparation of polyamide–imide resins, as a metal deactivator fuel additive (neutralizes the catalytic effect of copper associated with fuel oxidation), and in the production of polymers for synthetic fibers in the textile industry.
