Preparation method

Obtained by the reaction of morpholine with bromoethane:

Add morpholine to bromoethane slowly under stirring and cooling, and control the reaction temperature below 70℃. After charging, reflux the reaction for 6 hours. After recovering bromoethane, cool and neutralize with 50% sodium hydroxide solution to strong basicity. The oil layer is separated, the aqueous layer is extracted with ether, the extract is incorporated into the oil layer, the ether is recovered, dried with anhydrous sodium carbonate and then subjected to atmospheric pressure fractionation to obtain N-ethylmorpholine.

 

Applications

N-Ethylmorpholine is a medium strength tertiary amine catalyst, mainly used as a soft polyurethane foam catalyst of polyester type in polyurethane industry, with good epidermis formation performance and strong catalytic effect on gel reaction even after the foam rises to a high point, making the bubble pores expand to a large extent.

 

Uses:

Used as a solvent, also used in organic synthesis. It is used as solvent of oil and resin, and also used as intermediate of organic synthesis. It is soluble in water, alcohol and ether, and can be used as solvent, catalyst, intermediate of dyestuff, medicine and surfactant, and also used to produce preservative, emulsifier and paint.

 

 

Package

Packed in clean, dry, sealed and leak-free special plastic drums with a net weight of 20kg/25kg/180kg per drum.

 

Storage and transportation

When transporting Catalyst, it should be strictly protected from rain and staining, carefully and gently stored to prevent leakage from collision with hard objects. When storing Catalyst, it should be stored at room temperature in a ventilated and dry warehouse, avoiding humid environment, and the storage temperature should be kept below 25℃, avoiding sunlight as much as possible, and away from water and heat sources. To prevent moisture absorption and oxidation, it is recommended to fill the container with nitrogen.

 

Shelf life

Under proper storage conditions, the shelf life is 6 months from the date of manufacture, after which the product can be used after retesting.

 

Safety Information

Catalyst  is somewhat toxic and should be rinsed with soapy water promptly after contact with skin. Staff can wear eye protection or safety glasses for the purpose of eye protection. Eye wash and drenching equipment should be provided near the workplace. When working in places where contact with the product is possible, attention should be paid to personal hygiene and the skin in contact with the product should be washed with washing products before eating, smoking and leaving the workplace.

 

Leak handling

Stop spills as much as possible while ensuring safety. If a minor spill is found, treat it with sand or other absorbent material and place it in a clean, dry container for subsequent disposal. If a large spill occurs, the spilled material should be collected for subsequent disposal. Avoid entering groundwater or surface water as the material is not readily biodegradable. All collected spilled material should be disposed of in accordance with local environmental regulations.
