Is acetylene gas corrosive and is acetylene toxic?

Some. Acetylene is the simplest alkyne, also known as calcium carbide gas. The molecular formula CH, the chemical formula CH.

Colorless, flammable gas with aromatic odor. Melting point , boiling point 84 , relative density. There is a danger of violence in liquid and solid states or in gaseous states and under a certain pressure, and can be caused by factors such as heat, vibration, and electric sparks, so it cannot be stored or transported after pressurized liquefaction.

Insoluble in water, easily soluble in acetone, at 15 and a total pressure of 15 atmospheres, the solubility in acetone is 237 g liters, the solution is stable. Therefore, in the industry, acetylene is pressed into a steel drum or steel tank filled with porous substances such as asbestos to absorb acetone and then be pressed into it for storage and transportation.

Pure acetylene is a colorless, odorless, flammable and toxic gas.

Acetylene made of calcium carbide has a special odor due to the mixture of H2S and pH3.

Melting point (, boiling point -84, relative density, refractive index, refractive index, flash point (open cup), spontaneous ignition point 305. ** limit in the air. Slightly soluble in water, soluble in ethanol, benzene, acetone and other organic solvents.

At 15 μl, the solubility of acetylene in acetone is 237 g l, and the solution is stable. Industrial acetylene with a slight garlic odor. Acetylene, prepared from calcium carbide (calcium carbide), has a foul odor due to the presence of impurities such as phosphine[1].

Acetylene molecular weight 26 4, gas specific gravity 0 91 (kg m3), flame temperature 3150, calorific value 12800 (kcal m3) combustion rate in oxygen 7 5, pure acetylene burns about 2100 degrees in air, and can burn up to 3600 degrees in oxygen.

The chemical properties are very active, and can cause addition, oxidation, polymerization and metal substitution reactions.

It can make the purple color of potassium permanganate solution fade.

It can make the purple color of potassium permanganate solution fade. "Anything that can make the purple color of the potassium permanganate solution fade is acid, and everything that is corrosive is corrosive.

Pure acetylene.

The gas is non-corrosive. Although the triple bond is easy to open and undergo a variety of chemical reactions, it is not easy to react with metals in the steady state.

Pure acetylene is non-corrosive, but industrial acetylene is corrosive because it contains impurities such as hydrogen sulfide and phosphine.

Yes Chemically active, it can cause addition, oxidation, polymerization and metal substitution reactions.

Live flakes are not necessarily corrosive, no.

Acetylene is toxic. Acetylene, with the molecular formula C2H2, commonly known as wind coal or calcium carbide gas, is the smallest alkyne compound and is mainly used for industrial purposes, especially for welding metals. Acetylene is a colorless, extremely flammable gas at room temperature.

Pure acetylene is odorless, but industrial acetylene has a garlic smell due to the presence of impurities such as hydrogen sulfide and phosphine.

Industrially, acetylene is pressed into a cylinder filled with porous substances such as asbestos to absorb acetone and then be pressed into it for storage and transportation. In order to distinguish it from other gases, the color of acetylene cylinders is generally milky white, the rubber tubing is generally black, and the thread of acetylene pipes is generally left-handed threads (with radial discontinuous grooves on the nut).

Stockpile. Acetylene is usually packaged in a solvent or porous substance and packed into a cylinder. Store in a cool, ventilated warehouse.

Keep away from fire and heat sources. The storage temperature should not exceed 30. It should be stored separately from oxidants, acids and halogens, and should not be mixed.

Explosion-proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment.

The above content reference: Encyclopedia - acetylene.

Acetylene gas, flammable and explosive, and has a large calorific value, can be used for welding, it is still very dangerous.

Yes, flammable.

Hope to adopt, thank you.

Acetylene is a flammable gas. Acetylene is commonly known as aeolian coal and calcium carbide gas, and the large mold is the smallest member of the alkyne compound, and the main virtual imitation is mainly used for industrial purposes, especially in welding metals. Acetylene is a colorless, extremely flammable gas at room temperature.

Pure acetylene is an odorless difference, but industrial acetylene has a garlic smell because it contains impurities such as hydrogen sulfide and phosphine.

Pure acetylene is a microtoxic class that has the effect of weak anesthesia and preventing cell oxidation.

At high concentrations, oxygen is expelled from the air, causing simple asphyxiation. Acetylene is often mixed with phosphine, hydrogen sulfide and other gases, so it is often accompanied by the toxic effect of such poisons. Human exposure to 100 mg m3 can tolerate 30 60 min, 20% causes obvious hypoxia, 30% ataxia, 35% causes loss of consciousness for 5 min, and 10% acetylene in air for 5 h, and has mild poisoning reactions.

Long-term inhalation of non-lethal concentrations of the product in animals showed an increase in hemoglobin, reticulocytes, lymphocytes and neutropenia. Autopsy showed bronchitis, pneumonia, pulmonary edema, hepatic hyperemia, and fatty infiltrates.
