The features for DMI

(1) Excellent thermal and chemical stability

DMI has the ability to dissolve inorganic, organic compounds, and various resins, as well as its catalytic effect as a non-proton transfer polar solvent, making it an especially effective reaction solvent. The use of DMI can improve yield and effectively control side reactions while reducing reaction time.

(2) Hydrolytic resistance

DMI is quite stable under high-temperature alkaline conditions and does not undergo rapid decomposition. Compared to NMP, DMI's application range is expanded to include reactions under alkaline conditions.

(3) Organic reactions

In organic reactions, DMI has a higher acidic pKa value than NMR, making DMI more suitable as a solvent for nucleophilic substitution reactions. DMI has a high boiling point and stability, making DMI suitable for situations where solvent evaporation needs to be prevented. DMI has good solubility, can form a uniform reaction system, and accelerates the reaction rate and yield of metal salt catalysts.

(4) Wide range of applications

DMI is used as a transdermal absorption agent in medicine, to improve polymer properties in the field of polymers. DMI is used in the preparation of porous ultrafiltration membranes in liquid crystal materials, as a localization agent. As an organic reaction solvent, DMI promotes condensation reactions to prepare heterocyclic compounds and is suitable for a variety of chemical reactions.

Packaging And Transportation Of DMI

Considering the characteristics of the product, it should be handled with care during transportation to prevent collisions, exposure to rain, and contamination. The product should be stored in a ventilated, dry, and cool warehouse, away from sources of ignition and heat, and stored in a sealed manner.

The Packaging of DMI is 200kg/drum
