Application fields of morpholine

Morpholine  is widely used in rubber, medicine, coatings, pesticides, dyes, medical equipment and other fields, and has become one of the fine chemical products with important commercial uses.

Rubber additives

Morpholine is an intermediate in the preparation of many fine chemical products, the most important of which is widely used as an additive in rubber production. For example, the vulcanization accelerator OTTOS is produced. Its processing safety and delay effect are better than those of sulfenamide and benzomazole accelerators, and it has become the main accelerator for styrene-butadiene rubber, EPDM rubber and other general-purpose rubber; synthetic The vulcanizing agent DTDM can improve the scorch resistance and heat aging resistance of rubber. 1,4-Oxazinane is a new vulcanizing agent and accelerator for natural rubber and synthetic rubber. It has the characteristics of safe operation, easy dispersion, no blooming, no discoloration and no pollution of the rubber. Etc. The largest consumer area of morpholine in my country is the rubber industry. Currently, more than 50% of morpholine is used in the production of rubber additives.

Drug

The second largest consumer market for morpholine is the pharmaceutical industry. In medicine, it can be used to produce analgesics, sedatives, local anesthetics, respiratory and vasodilator stimulants, body strengthening drugs, antispasmodics and antimalarial drugs, such as morpholine, ibuprofen, naproxen, etc. that are common on the market. Sodium phenylacetate, dichloroaniline and other drugs. In agriculture, it can be used to produce high-efficiency and low-toxic pesticides, such as flumorpholine, dimethomorph, new fungicide butyromorph, etc.

Corrosion inhibitor

Due to its low toxicity and the fact that it will not cause great harm to the human body and the environment, morpholine has replaced dicyclohexylamine nitrite and cyclohexylamine carbonate in the field of metal gas rust prevention, such as mechanical instruments, automobiles, medical equipment, etc.

 Rust

The morpholine aqueous solution is weakly alkaline and can effectively neutralize the carbonic acid in the acidic aqueous solution. It is used as a corrosion inhibitor in boilers and other water circulation systems. The vapor pressure of morpholine is similar to that of water and can be dissolved in water at any ratio. It can maintain a constant pH value in the water circulation system and is therefore often used in conjunction with other amine compounds to solve special corrosion problems in the water circulation system.

Metalworking fluid additives

Due to the characteristics of low toxicity, weak alkalinity and miscibility with water, Mimi can be added to water-based metal working fluids to prevent metal rust, corrosion, sterilization and adjust the pH value of metal working fluids; in combination with water Adding a certain amount of morpholine or morpholine derivatives into the contacting lubricating oil as a corrosion inhibitor can effectively prevent corrosion of operating equipment parts; in petroleum storage tanks, pipelines and distillation equipment, adding petroleum carbonate morpholine can effectively to prevent corrosion

other

Morpholine can also be used to synthesize fluorescent whitening agents, aromatic hydrocarbon extractants, initiators and surfactants, textile auxiliaries, antioxidants, cleaners and polishes, etc. Morpholine aqueous solution is alkaline and can be used to remove hydrogen sulfide, carbon dioxide or hydrogen cyanide from acidic gases. As the research on morpholine continues to deepen, new uses of morpholine are constantly being developed, and the consumer market continues to expand, setting off a new upsurge in domestic research on morpholine and its derivatives.
