Preparation method:

Obtained by reacting morpholine with ethyl bromide:

Morpholine was slowly added into ethidium bromide under stirring and cooling, and the reaction temperature was controlled below 70℃. After addition, reflux reaction for 6 hours. After recovering the ethylene bromide, cool and neutralize with 50% sodium hydroxide solution to strong alkaline. Separate the oil layer, 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 fractionated at atmospheric pressure to obtain N-ethyl morpholine.


N-Ethylmorpholine is a medium-strength tertiary amine catalyst, which is mainly used as polyester-type polyurethane soft foam catalyst in the polyurethane industry, with good skin-forming properties, and still has a strong catalytic effect on the gel reaction after the foam rises to a high point, so as to make the bubble holes expand to a large extent.


Used as solvent, also used in organic synthesis. Used as a solvent for oils and resins, also used as an intermediate in organic synthesis. The product is soluble in water, alcohol, ether, can be used as solvents, catalysts, dyes, pharmaceuticals, surfactants, intermediates, but also for the production of preservatives, emulsifiers and coatings.

Storage and transportation:

Should be sealed and stored in dry, cool and ventilated warehouse


200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the packaging cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product. Store in a cool and dry place, keep the container sealed and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Store in a cool, ventilated warehouse. Keep away from fire and heat source. The temperature inside the warehouse should not exceed 30℃. Protect from direct sunlight. Keep the container sealed. Equipped with appropriate varieties and quantities of fire fighting equipment. Prohibit the use of mechanical equipment and tools that are easy to generate sparks. Load and unload lightly to prevent damage to packaging and containers.
