1,3-Dimethyl-2-imidazolidinone (DMI), identified by CAS 80-73-9, stands as a premier high-boiling polar aprotic solvent, renowned for its exceptional properties and widespread utility across numerous industrial sectors. As a leading manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer high-purity DMI, a colorless and transparent liquid that is indispensable in modern chemical processes and material science.

DMI's unique molecular structure imparts a remarkable combination of characteristics. It boasts high thermal and chemical stability, making it resilient under demanding reaction conditions. Unlike some conventional solvents, DMI is non-corrosive, contributing to safer operations and extended equipment life. Its high dielectric constant and excellent solvating ability allow it to effectively dissolve both inorganic and organic compounds, facilitating a broad spectrum of chemical transformations. Furthermore, DMI is notable for its lower viscosity compared to similar solvents, which enhances process efficiency and handling ease. With a boiling point typically around 222-225 °C and a flash point of 95-120 °C, DMI offers a safer alternative to many volatile organic compounds.

The versatility of DMI makes it an invaluable asset in various applications:

• Chemical Synthesis: DMI serves as an outstanding reaction solvent, particularly for nucleophilic substitution reactions. Its ability to accelerate anionic nucleophilic reactions through efficient cation solvation leads to higher yields and purer products in shorter reaction times. It is widely used in the synthesis of phenylether derivatives, amino compounds, and fluorobenzene derivatives, crucial intermediates for agrochemicals, medicines, and dyestuffs.


• Polymer Manufacturing: In the polymer industry, DMI is pivotal for producing heat-resistant thermoplastics. It accelerates the formation of amide and imide groups in the synthesis of polyamides and polyimides, yielding high molecular weight polymers. It also plays a role in controlling side reactions in polyethersulfone production and in treating films for improved uniformity, such as polyimide and polysulfone films.


• Electronics and Surface Treatment: Due to its low viscosity and high dielectric constant, DMI is an ideal solvent for electrolytic solutions in non-aqueous batteries. It also functions as an effective photo-resist stripper in electronic material processing, offering a more environmentally friendly alternative to traditional methods. As a surface treatment agent, DMI can significantly enhance the bonding strength of various materials, including ABS, polyimide, PPS, and Teflon, to epoxy resin adhesives.


• Cleaning Solutions and Dyestuffs: DMI enhances the performance of detergents, improving their ability to dissolve dirt and grime from glass and metal surfaces. When incorporated into inks with dyes and pigments, it produces prints with superior contrast and clarity, making images sharper and more vibrant.


• Petroleum Industry: Its high boiling point and thermal stability, combined with its non-azeotrope forming characteristic, make DMI an excellent choice for processes like liquid-liquid extraction, extractive distillation, and counter current washing. It is particularly effective as an extractant for BTX (benzene, toluene, xylene) due to its selective solubility for aromatic compounds and unsaturated hydrocarbons over paraffin hydrocarbons.

An important economic and environmental advantage of DMI is its reusability as a solvent, which contributes to increased utilization efficiency and considerable cost savings. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the DMI supplied maintains a high purity level of typically 99.5% minimum, meeting stringent industry standards. We package DMI in robust 200kg drums, ensuring safe transport and storage. Proper storage in cool, sealed conditions, protected from light and with an inert gas blanket, is recommended to maintain product integrity due to its hygroscopic nature and susceptibility to oxidation.
