Morpholine is a volatile organic chemical compound with the chemical formula C4H9NO. This chemical compound has the properties of two functional groups, amine and ether. In fact, morpholine is a chemically stable amino ether. Due to the presence of amines, morpholine is a base whose conjugated acid is morpholinium. This compound is widely used in the production of many chemicals as a corrosion inhibitor and also in detergents. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.
Physical and Chemical Properties:
Morpholine is a colorless liquid with a fishy odor that has a flashpoint of 100 degrees Fahrenheit and is corrosive to tissues, soluble in water, and denser than water.
It is soluble in acetone, benzene, ether, pentane, methanol, ethanol, carbon tetrachloride, propylene glycol, and other organic solvents, and its vapors are heavier than air and can form explosive mixtures with air.

Morpholine Synthesis:
Synthesis of industrial morpholine is possible by hydration of diethanolamine with sulfuric acid.
Morpholine can also be prepared using diethylene glycol and ammonia in the presence of pressure and catalyst.
Types of Morpholine Compounds:
This chemical compound is divided into two types based on the type of consumption:
Food grade: This compound is licensed (FDA) by the Food and Drug Administration to cover fruits and vegetables.
Industrial grade: Industrial morpholine is used in the production of various chemicals such as antiscalants and biocides anti-corrosion and other chemical products.
Morpholine Uses:
Morpholine is generally considered an additive and is used for a variety of purposes. In this section, we describe some of the applications of this chemical compound:
Corrosion inhibitors:
Morpholine is widely used as a neutralizing amine to prevent carbonic acid corrosion in steam boiler systems. Morpholine evaporates with the vapor in the system, and when the vapor becomes liquid, it liquefies with it, thus protecting the lines. Morpholine vapors can prevent corrosion of silver and other metals, as well as obscuring their surfaces by acids such as sulfur dioxide and hydrogen sulfide.
Rubber industry:
The most important application of morpholine is as an intermediate in the production of accelerators used in the rubber industry. Accelerators will be added to the rubber before production to speed up vulcanization.
rubber accelerators include MDS, DTOS, and NOBS, with MDS accounting for more than half of the accelerator market share.
medical science:
Another application of this chemical compound is in medicine and the pharmaceutical industry. Morpholine is used to produce a variety of local anesthetics, sedatives, analgesics, vascular and respiratory stimulants.
Agriculture industry:
In the agricultural industry, this material will be used as a protection and cover against insects and fungal contamination for fruit. Morpholine can also be used as a component in agricultural fungicides and microbial removal.
Organic synthesis:
In research and industry, it is used as a solvent for chemical reactions due to its low cost and high polarity.
Buy Morpholine:
Morpholine is one of the most widely used chemical compounds in various industries. That is why many industries are looking for high-quality morpholine.
To buy this chemical compound with the best quality, you can contact Shanghai Chemex experts and register your purchase.
Safety and Hazards:
When working with morpholine, be sure to use gloves to prevent this chemical from coming into contact with your skin. To protect the eyes, you should use protective glasses, and in case of contact of this chemical with the eyes, rinse the eyes with water for at least 15 minutes.
Before working with this material, make sure that the place is properly ventilated and it is better to use a mask to prevent inhaling the resulting vapors.
In case of accidental ingestion, do not make the patient vomit because the burning nature of morphine destroys the mucous membranes of the mouth, throat, esophagus and the possibility of it entering the lungs will increase medical problems.
Packing and Storage:
Keep the container tightly closed in a dry and well-ventilated place. Containers that are opened must be carefully resealed and kept upright to prevent leakage.
