Application

1. 1,3-Dimethyl-2-imidazolidinone CAS 80-73-9 is used to study functionalized hydrosilane dibasic transition metal complexes stabilized by photochemical formation of aryl silanes.

2. Aprotic dipolar solvent, 1,3-Dimethyl-2-imidazolidinone is often used as a carcinogen HMPA substitute.

3. Reaction solvent
Due to its excellent thermal and chemical stability, DMI has solubility in inorganic, organic compounds and various resins, and its catalytic effect as a non-protonic polar solvent makes it a particularly effective reaction solvent. . Using DMI, the yield can be improved and the side reactions can be effectively controlled while shortening the reaction time.

DMI can effectively promote various nucleophilic substitution reactions, such as the synthesis of phenyl ether derivatives, amino compounds and fluorobenzene derivatives. Its high dielectric constant and cationic solvation can catalyze anionic nucleophilic reactions. These synthetic products are used as intermediates for the synthesis of pesticides, drugs, dyes and high-performance resin monomers.

4. Petroleum products
DMI has a high boiling point and high thermal stability, and is not easy to form azeotropes with other substances. Therefore, it can be used in many industrial processes such as liquid-liquid extraction, countercurrent distribution, extractive distillation and countercurrent washing. DMI is a good BTX (benzene, toluene and xylene) extractant because it dissolves aromatic compounds and unsaturated hydrocarbons, but does not dissolve paraffin.

5. Polymer reaction solvent
1,3-Dimethyl-2-imidazolidinone CAS 80-73-9 is the only solvent used to produce heat-resistant thermoplastics. It is also effectively used as a solvent for various polymer synthesis processes and a detergent for polymerization and plastic molding. In the production of polyamide and polyimide resins, DMI accelerates the formation of amide and imine groups to obtain high molecular weight polymers, and the resulting solution is suitable for solution spinning to obtain high-temperature resistant polyimide fibers.

In the production of polyphenylene sulfide resin (PPS), electronic materials with very small amounts of organic impurities can be obtained by DMI. In the production of polyphenylene ether sulfone resin, DMI can effectively control the occurrence of side reactions and obtain high-quality polymer products. When polyimide resin and polysulfone resin are formed into films and polyether ketone resin films are stretched, treatment with DMI can make the films more uniform.

6. Photolithography process stripper
Due to its low viscosity and high dielectric constant, 1,3-Dimethyl-2-imidazolidinone CAS 80-73-9 can be used as an electrolyte solvent for high-performance lithium batteries. In addition, it has strong permeability, high boiling point and high temperature resistance, and can also be used as a stripper for silicon wafer photoresist. Its fast stripping and non-corrosive properties greatly simplify the stripping process and speed up the productivity of chip cutting.

7. Detergent
DMI is added to a mixture of surfactants, alkalis, alcohols and polyoxyethylene alkyl ethers to obtain a powerful detergent. Since DMI is very easy to dissolve dirt, it can also be used to prepare efficient cleaning solutions for cleaning glass and metal.

8. Dyes and pigments
Inks made by mixing DMI with solvent components and dyes and pigments can be printed in contrast, and the image is clear.

9. Surface treatment agent
DMI can be used as a surface treatment agent to improve the bonding strength of ABS, polyimide, PPS, Teflon and other materials with epoxy resin adhesives.

Packaging and Storage

200kg/drum

Storage temperature: 10 – 25℃ in a cool and ventilated warehouse, avoiding direct sunlight; do not store for a long time at temperatures below 5℃, as low temperatures can cause crystallization and solidification; keep away from heat sources.
Separation storage: Keep away from strong oxidants and strong reductants; although it is resistant to acids and alkalis, avoid long-term mixed storage with concentrated strong acids and strong alkalis.
Original factory sealed shelf life: 24 months; after opening, seal it and it is recommended to use it within 12 months; when absorbing moisture, the moisture level increases, and if there is no water reaction, the water needs to be removed again.

FAQ

Q: DMI is resistant to acids and alkalis. Can it be stored for a long time with concentrated acids and alkalis mixed together?
A: DMI is resistant to acids and alkalis in the reaction system, but it is not recommended to store it together with strong concentrated acids and alkalis under long-term conditions; even at high temperatures, it will slowly degrade. It is only suitable for short-term use during the reaction process.

Q: It absorbs water when opened. What should be done if the moisture level increases?
A: DMI is extremely prone to absorbing water; if used in ordinary processes, it can be used directly; for water-free synthesis, molecular sieves need to be used for vacuum distillation to remove water. If the moisture content is extremely high, it is recommended to scrap it. Make sure to tighten the bucket lid and seal it properly during storage.

Q: What is the minimum order quantity (MOQ)?
A: For industrial bulk goods, the regular MOQ is 25 kg; small samples can be provided for formula testing; for orders of custom specifications, it takes 15-25 working days; before placing an order, confirm the inventory and logistics schedule.

Q: What is the delivery lead time?
A: For in-stock products: 5-10 working days after receiving full payment; for high-purity/custom specifications orders: 15-25 working days; before placing an order, confirm the inventory and logistics schedule.

Q: What export documents can be provided?
A: COA analysis report, MSDS (SDS), packing list, commercial invoice; support FOB/CIF/CFR trade terms.

Slightly soluble in water (0.209 at 20℃), soluble in acid, ammonium salt, sodium thiosulfate, sodium chloride solution and glycerol. Even if water is added, it can no longer become calcium sulfate dihydrate. If the natural gypsum ore is completely dehydrated below 300℃, soluble anhydrous gypsum soluble in water can be generated; if the natural gypsum is heated to above 600℃, insoluble anhydrous gypsum is generated. When anhydrous calcium sulfate or plaster of Paris is mixed with an appropriate amount of water, it slowly solidifies. It is used as a retarder, adhesive, moisture absorbent, polishing powder, paper filling, gas desiccant, plaster bandage, and handicraft. Gypsum is used as a raw material for making cement, and it can adjust the setting time of cement. It is used as a coagulant in tofu making, yeast feed, dough regulator, and chelating agent. There are natural gypsum mines, and the byproducts of the phosphate industry contain calcium sulfate. The ammonium sulfate solution reacts with the calcium chloride solution, and the filtration, washing and precipitation can produce a pure product.
