The Urethane Formula is given below for students’ understanding. Extramarks provides simple explanations for various complex concepts to improve students’ understanding.
What is Urethane?
Urethane Formula is a carbamate-linked organic polymer chain. It is made by polymerising ethanol and carbamic acid. It is primarily employed as a coating and adhesive. It is found in the form of a white powder or a colourless crystal.
Polyurethane, one of the most important urethane compounds, is a polymer formed by the condensation polymerisation of urethane. Because of its insulating properties, it has a wide range of applications, including electrical potting. It is used to make fibres such as spandex and PUL nut Foams are the most common application, accounting for 67% of total usage.
Urethane Formula is a colourless and odourless crystalline chemical that emits lethal nitrogen oxides. When heat causes decomposition, this happens. It is primarily used in the production of amino resins, but it is also used in the production of pesticides, fumigants, cosmetics, and medications. Furthermore, urethane exposure can be harmful to the central nervous system, liver, and bone marrow. In general, urethane is a human carcinogen.
Urethane Formula Structure
Urethane Formula has the chemical formula NH2COOC2H5 and the molecular formula C3H7NO2.
Properties Of Urethane Formula
The chemical and physical properties of Urethane Formula are given below:
Physical Properties of Urethane
- Urethane Formula is initially observed as odourless, colourless crystals or as a white powder.
- It easily sublimates at 217 °F and 54 mm Hg.
- A saline flavour that is refreshing. The second type is colourless, columnar crystals or white granular powder.
- It tastes bitter, cold, and saline.
- Its boiling point ranges from 360 to 363 °F at 760 mm Hg.
- Its melting point ranges from 118 to 122 degrees Fahrenheit.
- It has a flashpoint temperature of 198 degrees Fahrenheit.
- Its solubility at 72° F is greater than or equal to 100 mg/mL. Finally, the density at 70 degrees F is 0.9862.
Chemical Properties of Urethane
Polyurethane and water are formed when Urethane Formula reacts with ethyl alcohol.
During the combustion of urethane, ammonia, carbon dioxide, and water are produced.
Use Of Urethane
The various uses of the Urethane Formula are given below:
- It is a key component of static and rigid foams used in refrigerators.
- It is used to make the foam that is used to make car seats, bumpers, and doors more comfortable.
- Polyurethane binders are used to attach organic matter to composite wood.
- It is used to seal fragile, pressure-sensitive underwater cables in the electronics industry.
Safety measures and Health Hazards are given below:
- This compound can harm the central nervous system and liver if exposed to it.
- It may also cause bone marrow suppression. It is thought to be a human carcinogen.
- When ethyl urethane is heated to decompose, toxic nitrogen oxide fumes are released.
