Benzene, 1,3-diethyl-2,4-diisocyanato-5-methyl- - Introduction
1,3-diethyl-2, is an organic compound called DEDDM for short. Its molecular formula is C14H18N2O2.
Nature:
DEDDM is a colorless to pale yellow liquid with a strong pungent odor. It is insoluble in water and soluble in organic solvents such as Alcohols, Ketones and aromatic hydrocarbons. It is stable in air, but will hydrolyze to produce harmful vapors and irritating gases when exposed to water.
Use:
DEDDM is mainly used as a crosslinking agent in room temperature curing coatings and adhesives. It has good wear resistance, oil resistance, chemical resistance and high temperature resistance, and can be used in automotive coatings, packaging materials, industrial primers and other fields.
Preparation Method:
The preparation of DEDDM is usually obtained by reacting dimethylformamide with ethyl formate to obtain 1, and then reacting with phosgene to obtain the target product.
Safety Information:
DEDDM has high toxicity and irritation, contact with skin, eyes or inhalation of its vapor can cause irritation and injury. Immediately after contact, flush with plenty of water and seek medical attention if necessary. During use and storage, take appropriate precautions to avoid contact with skin and inhalation of vapors. In addition, DEDDM should also be kept away from fire and high temperature environment and stored in a sealed container.
