Emergency measures and fire fighting methods for aqueous solution of ethylamine

Ethylamine aqueous solution (concentration 50%~70%) C2H5BNH2 45.1

Alias ​​aqueous solution of aminoethane, aqueous solution of ethylamine.

Classification of dangerous regulations and numbering of flammable liquids. GB3.1 class 31045. UN No. 2270; IMDG CODE 3121, page 3221, class 3.1.

Specifications 70% aqueous solution and 50% aqueous solution.

Uses rubber stabilizers, accelerators, detergents, insecticides, ion exchange resin production and mineralizers, dye intermediates, general reagents.

The physicochemical property is a colorless liquid with an odor of ammonia. The relative density of the 70% aqueous solution was 0.796. Melting point -81 ° C. The boiling point is 17 ° C. The refractive index is 1.3840. The vapor pressure was 299.7 kPa (20 ° C) and the vapor relative density was 1.6. Very soluble in water, the aqueous solution is strongly alkaline. Soluble in ethanol and ether.

The hazardous properties are flammable. Flash point <-18 ° C, self-ignition point 385 ° C. Vapor can form an explosive mixture with air, with an explosion rating of 3.5% to 14.0%. In case of high heat, open flame, or oxidant, there is a danger of burning. The aqueous solution is strongly alkaline and corrodes many non-ferrous metals such as aluminum and zinc. Through the respiratory tract into the body, there are symptoms such as sore throat, cough, shortness of breath, difficulty breathing, and can produce pulmonary edema. Irritating and corrosive to eyes, skin and mucous membranes.

Emergency measures Fire-fighting methods: use dry powder, cement, anti-solvent foam, carbon dioxide to extinguish fire, a small area can be saved with misty water. First aid: Patients who inhale vapor should be removed from the contaminated area, rested and kept warm. Severe cases require medical treatment; eyes are stimulated with water to rinse, severe cases of splashing into the eyes for medical treatment; skin contact first rinse with water, then thoroughly washed with soap; accidentally gargle immediately, drinking water and dilute acetic acid or vinegar, and sent to the hospital Treatment.

Storage and transportation instructions packaging mark: flammable liquid. Sub-mark: Corrosive. Packing method: (II) class, glass bottle outer wooden box or calcium plastic box reinforced inner packing material or iron drum. Storage and transportation conditions: Stored in a cool, ventilated warehouse, the storage temperature does not exceed 10 °C, and must be cooled and stored during the hot season. Leakage treatment: first cut off all fire sources, wear gas masks and gloves; rinse with water, dilute the sewage into the wastewater system; fogging water curtains should be set around the large area to suppress explosion.
