m -Xylylenediamine is a chemical compound that is used in the manufacture of plastics.
Manufacturing
m -Xylylenediamine can be produced by reducing m -benzenedicarbonitrile with hydrogen in the presence of ammonia using a cobalt catalyst.
properties
The spectroscopic data of m -xylylenediamine are given in the literature.
use
Similar to the phenylenediamines , m -xylylenediamine is also used as a crosslinker for epoxides and for the production of polyurethanes. The thermoset made from bisphenol A diglycidyl ether cross-linked with m- xylylenediamine has such advantageous properties that it is used as a material in construction and automotive engineering.
