68533-01-7 - Introduction
1,1 '-trans-cyclohexane-1,4-diyldiurea, also known as 1,4-cyclohexanediurea, is an organic compound. Its molecular formula is C8H16N4O2. The following is a description of its nature, use, preparation and safety information:
Nature:
1,1 '-trans-cyclohexane-1,4-diyldiurea is colorless to light yellow crystalline with several crystal morphologies. It is stable at room temperature, insoluble in water, but soluble in polar organic solvents such as alcohols and ketones.
Use:
1,1 '-trans-cyclohexane-1,4-diyldiurea is commonly used as a chain extender and crosslinking agent for polyurethane products. It can increase the hardness, strength and wear resistance of polyurethane, and improve the chemical and thermal stability of polyurethane. Therefore, it has a wide range of applications in the manufacture of polyurethane elastomers, coatings, adhesives and plastics.
Preparation Method:
1,1 '-trans-cyclohexane-1,4-diyldiurea can be produced by the reaction of cyclohexanedione and urea. The specific preparation method is to react cyclohexanedione and urea in a molar ratio of 1:2 in a suitable solvent, and commonly used solvents include methanol, ethanol, acetone, etc. The reaction temperature is generally carried out at room temperature, the reaction time is short, and the generated product is crystallized and filtered to obtain 1,1 '-trans-cyclohexane-1,4-diyldiurea.
Safety Information:
1,1 '-trans-cyclohexane-1,4-diyldiurea has no obvious toxicity and irritation. However, it is still necessary to comply with general laboratory safety regulations during use and handling, such as wearing protective gloves, glasses and laboratory clothes, and avoiding contact with skin and inhalation of dust. Keep away from fire and oxidant during storage to prevent the risk of fire and explosion. Disposal shall be carried out in accordance with local environmental standards.
