51163-24-7 - Introduction
Cyclohexyl methyl isocyanate (Methyl isocyanate) is a colorless liquid with a pungent odor. Its chemical formula is C4H7NO and its molecular weight is 83.1g/mol. The following is a description of the properties, uses, preparation methods and safety information of cyclohexyl methyl isocyanate:
Nature:
-Cyclohexyl methyl isocyanate is a flammable liquid at room temperature and can form a flammable mixture with air.
-It is a highly volatile compound that is strongly irritating to the skin, eyes and respiratory tract.
-Cyclohexyl methyl isocyanate decomposes faster in water and can also react with other organic compounds.
Use:
-Cyclohexylmethyl isocyanate is mainly used in the synthesis of polyurethanes. These polymers are widely used in the manufacture of foams, elastic fibers and coatings.
-It can also be used as an intermediate for adhesives, insecticides and fungicides.
Preparation Method:
-Cyclohexylmethyl isocyanate is generally obtained by reacting methanol with an isocyanate.
-This reaction process needs to be carried out at an appropriate temperature and reactant ratio, and the reaction is promoted by an appropriate catalyst.
Safety Information:
-Cyclohexylmethyl isocyanate is toxic to humans and can enter the body through inhalation, skin contact or ingestion.
-Exposure to high concentrations of cyclohexyl methyl isocyanate may cause serious health problems, such as respiratory irritation, eye and skin irritation, and toxic symptoms.
-Long-term or heavy exposure may cause damage to the reproductive system, liver, and respiratory system.
-When using cyclohexyl methyl isocyanate, strict safety measures must be taken and relevant safety procedures must be followed. In the event of an accident that poses a threat to human health, it is necessary to take appropriate emergency measures immediately, evacuate quickly from the scene of the accident and seek medical assistance.
