Morpholine overview

Morpholine, also known as morpholine, is an organic compound with the molecular formula C4H9NO, a colorless oily liquid. It has an odor of water absorption and ammonia. A sulphuric acid dehydration cyclization process can prepare diethanolamine. It is produced industrially from diethylene glycol and ammonia in the presence of pro-hydrogen conditions and catalysts. It is mainly used to manufacture rubber vulcanization accelerators and the synthesis of surfactants, textile printing and dyeing auxiliaries, pharmaceuticals, and pesticides. It is also used as a corrosion inhibitor for metals. It is also used as a solvent, dyestuff, resin, wax, shellac, casein, etc.

Morpholine | Role and use

Morpholine is mainly used in the production of rubber vulcanization auxiliaries and the synthesis of surfactants, textile printing, and dyeing auxiliaries, pharmaceuticals, and pesticides. Morpholine is also used as a catalyst for cis-butadiene's polymerization, as a preservative, as an optical bleaching agent, and as a solvent for dyes, resins, waxes, early gum, casein, etc. Morpholine in salts is also widely used, such as morpholine hydrochloride as an intermediate in organic synthesis; morpholine fatty acid salts as fruit and vegetable epidermis or melon and fruit vegetables as a film agent can properly inhibit the role of the base gas to prevent water volatilization and epidermal shrinkage. Because of its unique chemical properties, morpholine has become one of the world's most important industrial fine petrochemicals. What can widely use in the manufacture of NOBS, DTOS, and MDS to promote rubber vulcanization auxiliaries, rust inhibitors, anti-corrosion cleaners, anti-scaling agents, painkillers, local anesthetics, sedatives, respiratory and vascular stimulants, surface activators, optical bleaching agents, fruit preservatives, textile? It has a wide range of rubber, pharmaceutical, pesticide, dyestuff, and paint industries. What can use it to produce important drugs such as morpholine guanidine, virus spirit, ibuprofen, naproxen, dichloroaniline, and sodium phenylacetate?

2. Eye contact: Immediately lift eyelids and flush thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.

3. Inhalation: Get out of the area quickly and into the fresh air. Keep airway open. If breathing is difficult, administer oxygen. If breathing stops, give immediate artificial respiration. Seek medical attention.

4. Ingestion: Rinse the mouth with water and give milk or egg white. Seek medical attention.

Firefighting measures

1. Hazardous characteristics: flammable, in contact with an open flame, high heat, or oxidizing agents, there is a risk of combustion and explosion. Decomposition by heat gives off toxic nitrogen oxide fumes.

2. Harmful combustion products: carbon monoxide, carbon dioxide, nitrogen oxides.

3. Fire fighting methods: Move the container from the fire to an open area if possible. Spray water to keep the container cool until the fire is extinguished.

4. Extinguishing agents: Soluble foam, dry powder, carbon dioxide, sand, and earth.

Emergency response to spills

1. Emergency response: quickly evacuate people from the spill contaminated area to a safe area and isolate and strictly limit access. Cut off the source of the fire. Advise emergency responders to wear self-contained positive pressure respirators and gas-protective clothing. Do not come into direct contact with the spill. Cut off the source of the spill if possible. Prevent flow into restricted spaces such as sewers and flood drains.

2. Small spills: adsorb or absorb with sand or other non-combustible materials. It can also be flushed with large water quantities, diluted with wash water, and put into the wastewater system.

3. Large spills: Construct an embankment or dig a pit into containing it. Cover with foam to reduce vapor hazards. Spray aerosol water to cool and dilute vapors, protect personnel on-site and dilute spill to non-combustible material. Transfer to a tanker or special collector with explosion-proof pump, recycle or transport to waste disposal site
