Diglycidyl aniline is an aromatic organic chemical in the glycidyl compound family.[1] It is used to reduce the viscosity of epoxy resin systems.[2] It has the empirical formula C12H15NO2 and the IUPAC name is N,N-bis(oxiran-2-ylmethyl)aniline. The CAS number is 2095-06-9.[3][4] It is REACH registered in Europe with the EC number 218-259-5.[5] A key use is in the viscosity reduction of epoxy resin systems functioning as a reactive diluent.[6][7]

Manufacture and synthesis

[edit]

Many glycidyl ethers are manufactured by addition of epichlorohydrin to a species with the aid of a Lewis acid as catalyst to form a halohydrin. This process is followed by washing with sodium hydroxide in a dehydrochlorination reaction.[10] This diglycidyl compound being basic and nitrogen based, does not need this type of catalyst.[11][12] One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight in addition to viscosity.

Uses

[edit]

The use of the diluent in epoxy systems affects the mechanical properties and microstructure of epoxy resins.[13][14][15][16][17] The kinetics of cure of this Diglycidyl amine with epoxy resin networks have been studied.[18] It has also been used to synthesize other materials including ion-exchange resins.[19][20][21]

Toxicity

[edit]

The toxicity profile has been studied and published.[22]
