1. Mainly used as CO2, H2S and SO2 and other acidic gas absorbent, non-ionic surfactant, emulsifier, polishing agent, industrial gas purification agent, lubricant.Iminodiethanol, also known as diethanolamine, is an intermediate of the herbicide glyphosate.Used as a purifying agent for gas, also used as a raw material for synthetic drugs and organic synthesis.

2. Both morpholine and diethanolamine are intermediates that are synthesized organically and are used, for example, in the production of certain optical bleaching agents in the textile industry, the fatty acid salts of morpholine as preservatives, and in the production of the central depressant fulcodine or as solvents.Diethanolamine is used in analytical chemistry as a reagent and as a stationary solution for gas chromatography to selectively retain and separate alcohols, dialcohols, amines, pyridines, quinolines, piperazine, mercaptans, sulfides, and water.

3. Diethanolamine is an important corrosion inhibitor, which can be used in boiler water treatment, automobile engine coolant, drilling and cutting oil and other lubricating oil to play a corrosion inhibition effect.It is also used as an absorbent to purify acid gas in natural gas.Used as an emulsifier in a variety of cosmetics and pharmaceuticals.In the textile industry as a lubricant, but also as wetting agent and softener and other organic synthetic raw materials.

4. Used as acid absorbent, plasticizer, softener and emulsifier in adhesives.It is also used as an absorbent for acidic gases (such as hydrogen sulfide, carbon dioxide, etc.) in petroleum gas, natural gas and other gases.It is the raw material of synthetic medicine, pesticide, dye intermediate and surfactant.Used as emulsifier of oils and waxes under acidic conditions, softener of leather and synthetic fibers.Used as thickener and foam improver in shampoo and light detergent.Also used as detergent, lubricant, brightener and engine piston ash remover.

5. Used as complexing agent for silver, cadmium, lead and zinc plating.

6. Used as analytical reagents, acid gas absorbers, softeners and lubricants, and in organic synthesis.

4 - First Aid Measures


First aid methods for different exposure routes:

     Inhalation: 1. Remove the source of pollution or move the patient to a place with fresh air.

                2. If breathing is difficult, trained personnel should provide oxygen under the instructions of the doctor.

                3. The patient avoids unnecessary movement.

                4. Symptoms of pulmonary edema may last 48 hours.

                5. Seek medical attention immediately.

     Skin contact: 1. Wear impermeable gloves when necessary to avoid touching the chemical.

                2. Rinse the contaminated parts gently with warm water for 20-30 minutes.

                3. If the irritation persists, do not stop after repeated washing. If necessary, the ambulance is ready to rescue.

                4. Take off contaminated clothes, shoes and leather accessories in the flushing water.

                5. Seek medical attention immediately.

                6. Contaminated clothing, shoes and leather accessories must be completely decontaminated before use or discard.

      Eye contact: 1. Wear impermeable gloves when necessary to avoid touching the chemical.

                2. Immediately open the eyelids and rinse the contaminated eyes with gentle flowing warm water for 20 minutes.

                3. Use normal saline to rinse when possible, and do not interrupt the rinse.

                4. Avoid washing water into unaffected eyes.

                5. If the irritation persists, rinse repeatedly.

                6. Seek medical attention immediately.

      Ingestion: 1. If the patient is about to lose consciousness or convulsions, do not feed anything by mouth.

                2. If the patient is conscious, let him rinse his mouth thoroughly with water.

                3. Do not induce vomiting.

                4. Drink 240~300CC of water to the patient to dilute the chemicals in the stomach; if possible, give milk after drinking the water.

                5. If the patient vomits spontaneously, let him lean forward to reduce the risk of inhalation, and let him rinse his mouth and repeatedly give water.

                6. Seek medical attention immediately.
