Is ethanolamine used for hydrogen sulfide removal from dry gas a non-flammable substance?

2-Hydroxyethylamine 1. Physical and chemical properties: National standard code 82504; CAS number 141-43-5; Chinese name: 2-Aminoethanol; English name: Monoethanolamine； 2-Aminoethanol, also known as ethanolamine ； 2-Hydroxyethylamine molecular formula C2H7NO ； HO(CH2)2NH2: Appearance and properties – Colorless liquid with an ammonia-like odor. Molecular weight: 61.08. Vapor pressure: 0.80 kPa at 60°C. Flash point: 93°C. Melting point: 10.5°C. Boiling point: 170.5°C. Solubility: Miscible with water; slightly soluble in benzene; miscible with ethanol, carbon tetrachloride, and chloroform. Density: Relative density (water=1): 1.02 ； Relative density (air=1): 2.11. Stability: Stable. Hazard symbol: 20 (alkaline corrosive). Main uses: Used as a chemical reagent, solvent, emulsifier, rubber accelerator, corrosion inhibitor, etc. 2. Impact on the environment: I. Health hazards. Routes of exposure: Inhalation, ingestion, dermal absorption. Health hazards: Vapors are irritating to the eyes and nose. Eye contact with this liquid product can cause eye damage ； Skin contact causes stinging and burning. Oral administration damages the mouth and digestive tract. II. Toxicological data and environmental behavior Acute toxicity: LD50 2050 mg/kg (oral, rats) ； 1000mg/kg (rabbit dermal) ； LC50: 2120 mg/m3, 4 hours (inhalation in rats). Subacute and chronic toxicity: When rats were exposed to 100–200 mg/m3 for 6 hours per day, 5 days per week, it led to central nervous system depression and changes in conditioned reflexes ； When rabbits were exposed to 24 mg/m3 for 35 days, their central nervous system was somewhat suppressed, and irritation occurred on their skin. Hazardous properties: It poses a risk of combustion when exposed to high temperatures, open flames, or oxidizing agents. It reacts violently with strong acids such as sulfuric acid, nitric acid, and hydrochloric acid. Combustion (decomposition) products: carbon monoxide, carbon dioxide, nitrogen oxides. 3. On-site emergency monitoring methods: 4. Laboratory monitoring methods: High-performance liquid chromatography; refer to the “Manual of Analytical Chemistry” (Volume 4, Chromatographic Analysis), Chemical Industry Press. 5. Environmental standards: In the former Soviet Union, the maximum allowable concentration of harmful substances in workshop air is 0.5 mg/m3 (former Soviet Union, 1975); the maximum allowable concentration of harmful substances in water is 0.5 mg/L, while the olfactory threshold concentration in water is also 0.5 mg/L. In the United States, the standard for workshop air quality is 6 mg/m3. 6. Emergency response measures: I. Emergency response to leaks: Evacuate people from the area affected by the leak to safe areas; restrict access to unauthorized persons in that area. It is recommended that emergency responders wear gas masks and chemical protective clothing. Do not come into direct contact with the leak; seal it up only when safety is ensured. It is absorbed by mixing with sand or other non-flammable adsorbents, and then collected and transported to a waste disposal site for disposal. It can also be rinsed with a large amount of water, and the diluted rinse water is discharged into the wastewater system. In the event of a large-scale spill, it should be contained using dikes, and then collected, transferred, recycled, or disposed of after being rendered harmless. II. Protective Measures: Respiratory protection: Wear a gas mask when there is a possibility of exposure to its vapors. It is recommended to wear a self-contained breathing apparatus during emergency rescue or evacuation. Eye protection: Wear chemical safety goggles. Protective clothing: Wear work clothes (made of corrosion-resistant material). Hand protection: Wear rubber gloves. Others: Smoking, eating, and drinking are prohibited at the work site. After work, take a shower and change clothes. Conduct pre-employment and regular health checks. III. First aid measures: Skin contact: Remove contaminated clothing and immediately rinse thoroughly with flowing water. Eye contact: Immediately lift the eyelids and rinse with flowing water or saline for at least 15 minutes. Or rinse with a 3% boric acid solution. Seek medical attention immediately. Inhalation: Quickly move to a place with fresh air. Perform artificial respiration if necessary. Seek medical attention. Ingestion: Those who accidentally ingest it should rinse their mouth immediately and be given milk or egg white to drink. Seek medical attention. Fire extinguishing methods: fog water, carbon dioxide, sand, foam, dry powder.

Simply put, how many organic compounds are non-flammable? Excluding perfluorochlorohydrocarbons. Generally, molecules rich in atoms such as C and H are flammable, while those containing peroxyl groups, nitro groups, chlorate groups, etc., act as accelerants for combustion.

Go back and collect some samples to give it a try, idiot

Ethanolamine is of course flammable, with a flash point of 93°C. Combustion decomposition products: carbon monoxide, carbon dioxide, nitrogen oxides.

Reply to Floor 6: In 2008, the samples I obtained were non-flammable; so I ask everyone, now you have nothing to say, right!

Replying to floor 9: Do you know what organic flame retardants are? Do you know halogenated alkanes?

OP, this question is quite interesting. Although it’s been many years, I still want to reply. How does your non-flammability sampling work (i.e., what is the method for achieving non-flammability)? Does that mean it’s not flammable if it can’t be lit with a lighter? Some things are non-flammable because the temperature isn’t high enough; try throwing them into a fire – it will definitely burn fiercely. Ethanolamine is undoubtedly a combustible substance, but certainly not highly flammable. And it’s category C. Also, discuss with the 12th floor: do halogenated alkanes have flame-retardant properties? For example, o-dichlorobenzene is flammable, as is polyvinyl chloride. Are there any flame retardants that are completely non-flammable? I want to know too. What is the structural formula? I hope the expert can discuss this

I really haven’t thought about this before. It seems necessary to gain a thorough understanding of the properties of the additives used in my device

Flame retardancy also applies under certain conditions; pour it into the furnace and see if it catches fire
