N-formylmorpholine is produced by the reaction of morpholine with formic acid. The reaction is carried out in the presence of a catalyst such as hydrochloric acid or sulfuric acid. The reaction is exothermic, and the product is a colorless water-soluble liquid.
The reaction is usually performed as a batch process. Morpholine and formic acid are mixed in the presence of a catalyst and the reaction is heated to the desired temperature. The reaction is then allowed to proceed for a period of time before cooling and isolation of the product.
The yield of the reaction is usually high and the product is of high purity. The reaction is relatively simple to perform and requires relatively inexpensive equipment.
N-Formylmorpholine is a valuable chemical intermediate. It is used in the production of a variety of chemicals, including pharmaceuticals, pesticides, and plastics. Also used as a solvent and corrosion inhibitor.
The production process of N-formylmorpholine is safe and environmentally friendly. The reaction does not produce any harmful by-products, and the products are not hazardous substances.
The production of N-formylmorpholine is a growing industry. The demand for the product is increasing, and the price of the product is also increasing. The future of the industry is bright.
N-formylmorpholine is an important Organic solvents and fine chemical raw materials. It can be used for desulfurization of natural gas, synthesis gas, flue gas, natural gas condensate and gasoline, etc.; it is the best extraction solvent for petroleum aromatics equipment, and aromatics can be recovered by extraction and distillation. It has good selectivity, thermal stability and Good chemical stability, non-toxic, non-corrosive.
There are many ways to produce N-formylmorpholine, one of which is the production of N-formylmorpholine by morpholine enamine oxidation. The method is to dissolve morpholine and aldehyde with α-hydrogen in pyrimidine or dichloromethane at a molar ratio of 1:1.2, pass through oxygen and irradiate with a 500 W tungsten lamp for 40 min, morpholine and aldehyde undergo condensation reaction, and Dehydration produces enamine, then add 1.2 times the oxygen of morpholine to the reaction, and add hematoporphyrin as a photosensitizer to catalyze the oxidation reaction, the double bond of enamine is broken to generate N-formylmorpholine.
Another production method is the formic acid production process. N-formylmorpholine is converted from formic acid morpholine. On the one hand, formic acid morpholine is neutralized with acid and alkali to form a salt, and N-formylmorpholine is dehydrated to produce N-formylmorpholine. Therefore, the product still has a part of salt, the purity is not high, and it can be used for a long time It can crystallize and block the pipeline; on the other hand, the raw material contains acid and water, and due to the saturation of N-formylmorpholine, the content of moisture, free acid and morpholine in the product is higher.
