Difference between pure MDI and liquefied MDI
In the chemical industry, MDI(Mixed-Solvent Diels-Alder) is a high-performance solvent system that is widely used in organic synthesis and chemical reactions. MDI consists of two solvents: one is dimethylformamide (DMF) and the other is diethyltoluene (DEB). Its name comes from the Diels-Alder reaction, which is an important organic chemical addition reaction.
Pure MDI
Pure MDI is the full name of dimethylformamide (DMF), is an inorganic solvent, composed of methyl group and carbonyl group. Its chemical formula is (CH3)2N (O)(CH3)2. Pure MDI has the following characteristics:
- Physical: Pure MDI at room temperature is a colorless liquid, with strong polarization and high conductivity.
- Chemical: pure MDMDI is a stable organic solvent, at room temperature is not easy to decompose, but in the strong acid or strong oxidant may be decomposed.
- Application: pure MDI is widely used in organic chemical synthesis, fore in the laboratory as a solvent, but also for some special reaction conditions control.
Liquefied MDI
Liquefied MDI is actually a liquefied form of DMF, I .e., MDI in which DMF is converted from a gaseous state to a liquid state by compression or cooling. The physical properties of liquefied MDI are similar to those of pure MDI, but its application range is wider.
