Toluene Diisocyanate

 

Toluene Diisocyanate Introduction:

Toluene diisocyanate (TDI) is a widely used chemical that belongs to the class of dopamine topological isocyanate linkers. It is usually a yellow to brown liquid with a less clear, colorless consistency.

Applications:

TDI can be used as a coupling agent in various applications such as polyurethane foam boards, coatings and sealants, etc. Toluene diisocyanate is mainly derived from 2,4- and 2,4-and 2,6-Two benzyl isocyanates.

TDI can be transported and stored by dissolving in other organic solvents. However, this also increases the potential health and safety risks of TDI during production and use. If used incorrectly, TDI may cause irritation and damage to the respiratory system, eyes and skin. Therefore, take appropriate safety measures and safeguards when handling TDI.

In conclusion, TDI is an important coupling agent, but there are also potential safety problems. Anyone who produces or uses it needs to be highly vigilant and protect their own health and safety.

1.4-Butanediol

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.
