Diethyltoluene diamine CAS 68479-98-1 (English name: Diethyltoluene diamine) refers to a mixture of two isomers of Diethyltoluene diamine, namely a commercialized mixture of two isomers: 3,5-Diethyl-2,4-diaminotoluene (3,5-Diethyltoluene-2, 4-diamine) 76% and 3,5-Diethyl-2,6-diaminotoluene (3,5-Diethyltoluene-2, 6-diamine) 24%, abbreviated as DETDA. At room temperature, it is a light yellow to reddish brown transparent liquid with an ammonia odor, slightly soluble in water, soluble in polar organic solvents such as alcohols, ethers, ketones, and has good compatibility with polyethers and polyester polyols. Long term exposure to the air can darken the color. Diethyltoluene diamine is flammable and highly corrosive. It can cause irritation and severe burns in contact with skin and eyes, and is harmful if taken by mistake. Specific toxicity data is lacking, and its toxicity can be referred to as toluene diamine. The main uses are curing agents, antioxidants, and chain extenders; Lubricants, polyurethane raw materials, amine catalysts, etc. The molecular formula is C11H18N2.

Chinese name: Diethyltoluene diamine

Foreign name: Diethyltoluenediamine

Molecular weight: 178.28

Molecular formula: C11H18N2

EINECS number: 270-877-4

CAS No: 68479-98-1

Main purpose

Diethyltoluene diamine is used as a chain extender for reaction injection molding of polyurethane, as well as a curing agent for polyurethane coatings, epoxy resins, and alkyd resins. Pesticides, dye intermediates, plastics, rubber, oil antioxidants.

Diethyltoluene diamine is an aromatic diamine curing agent for polyurethane elastomers and epoxy resins, used in casting, coatings, adhesives, and as a chain extender for polyurethane and polyurea elastomers. It has a fast reaction speed with polyurethane prepolymers and is mainly used for reaction casting molding of polyurethane systems and spraying polyurethane (urea) elastic coating systems. It has advantages such as fast reaction speed, short demolding time, high initial strength, hydrolysis resistance, and heat resistance of products. In addition, this product can also be used as an antioxidant for elastomers, lubricants, and industrial oils, as well as an intermediate for chemical synthesis.
