23138-50-3 - Introduction
4-ethylphenyl isocyyanate is an organic compound with the chemical formula C9H9NO. The following is a detailed description of its nature, use, formulation and safety information:
Nature:
4-ethylphenyl isocyyanate is a colorless to pale yellow liquid with a pungent odor. It is soluble in organic solvents such as ethanol and methylene chloride, and almost insoluble in water.
Use:
4-ethylphenyl isocyyanate is mainly used in the field of organic synthesis. It is an important intermediate for the preparation of some chemicals, such as dyes, fluorescent dyes, rubber processing aids, pharmaceuticals and pesticides. It can also be used as a reagent in research and laboratories.
Method:
4-ethylphenyl isocyanate is usually obtained by reacting benzaldehyde (ethylbenzene) with sodium cyanide. First, benzaldehyde reacts with trimethylamine to form the corresponding amino acid salt. Then, under alkaline conditions, the amino acid salt reacts with sodium cyanate to produce 4-ethylphenyl isocyyanate.
Safety Information:
4-ethylphenyl isocyyanate is irritating and may cause eye and skin irritation, respiratory and digestive tract irritation. Therefore, wear appropriate personal protective equipment, such as protective gloves and glasses, and ensure adequate ventilation during use. In case of contact with skin or eyes, rinse immediately with plenty of water and consult a doctor. In addition, 4-ethylphenyl isocyyanate should be stored in a sealed container, away from ignition and oxidizing agents.
