Production capacity and prospect of methyl morpholine in china. At present, the production capacity of morpholine in China is about 15,000 tons/year, and the annual output is about 8,000 tons. At present, many enterprises plan to install new morpholine plants. if the accelerator NOBS is banned in China before 2005, the situation of morpholine oversupply will be very obvious. moreover, many foreign countries will not import products from China, and the development prospect of morpholine is worrying. therefore, it is very important to vigorously develop the downstream products and applications of morpholine.

At present, many morpholine plants in China produce accelerator products with low purity. Therefore, it is necessary to carry out technical transformation in the future to produce high-purity pharmaceutical products and promote the development of pharmaceutical products. Morpholine is used as metal corrosion inhibitor in foreign countries, mainly as metal gas antirust agent to prevent metal atmospheric corrosion, but China has just started.

Analysis of morpholine production capacity and prospect in China

Morpholine has been widely used in mechanical instruments, automobiles, medical devices, military industry and other fields as a metal atmospheric antirust agent abroad. At present, dicyclohexylamine nitrite and cyclohexylamine carbonate are mainly used at home and abroad, which have great toxicity to human body and environment and restrict the popularization and application of gas-phase antirust agents. Morpholine as a metal gas-liquid corrosion inhibitor has the advantages of low toxicity and good development prospects.

With the development of petrochemical industry in China, high-quality and low-cost raw materials will be provided for morpholine production, and the price of morpholine will decrease accordingly, which will be beneficial to the application in metal anticorrosion. In addition, morpholine can also be used as PH regulator, gas absorbent, synthetic herbicide, etc., and domestic development and research should be strengthened to promote the consumption and development of morpholine.

The downstream products of morpholine that deserve special attention include N- formylmorpholine, N- ethylmorpholine, morpholine ethanol, N- acrylylmorpholine, N- methylmorpholine, N- aminomorpholine, 4-(2- aminoethyl) morpholine, 2- hydroxy -3- naphthoic acid -(3- morpholine)-propionamide, etc. In addition, some derivatives are being developed continuously.
