Ethyl Acrylate Liquid properties and stability

Ethyl Acrylate Liquid colorless liquid, volatile. Miscible with ethanol, ether, soluble in chloroform, slightly soluble in water.

Ethyl Acrylate Liquid is flammable, its vapor and air can form explosive mixtures, can cause combustion and explosion when exposed to fire and high heat. It can react strongly with oxidizing agent, Ethyl Acrylate CAS 140-88-5 vapor is heavier than air, it can diffuse to far away place in low place, it will catch fire when it meets ignition source. It is easy to self-polymerize, and the polymerization reaction increases sharply with the rise of temperature. Temperature over 20 ℃, can polymerization heat accumulation, causing an explosion.

Production method of Ethyl Acrylate Liquid

There are six production methods of Ethyl Acrylate CAS 140-88-5: ethylene cyanohydrin method; high-pressure Reppe method; improved Reppe method; β-propiolactone method (Goodrich method); hydrolysis of acrylonitrile and alcohol; propylene oxidation method. Nowadays, acrylonitrile method, β-propiolactone method, acetylene-based Reppe method and propylene oxidation method are the most widely used production methods. Among them, the propylene oxidation method is the most adopted method.

• 1. Acrylonitrile methodThis method is actually the development of early cyanoethanol method, the first step is to generate acrylamide sulfate by heating and hydrolyzing acrylonitrile with sulfuric acid, and the second step is to esterify it with alcohol to generate the corresponding acrylic ester, with the by-production of ammonium bisulfate.
• 2.β-Propiolactone methodVinyl ketone and anhydrous formaldehyde in the presence of aluminum trichloride, at 25 ℃ for the gas-phase reaction into β-propanolactone, can not be purified, directly with alcohol and sulfuric acid reaction, the generation of the corresponding acrylate. This method of high purity products, by-products and end of the reaction of the material can be recycled, high yield, simple reaction conditions, suitable for continuous production, but the raw material cost is higher.
• 3. Acetylene as raw material Raper methodDuring the Second World War, Leiper found that there are two ways to make acetylene, carbon monoxide and water or alcohol reaction to generate acrylic acid or acrylate. One is called the stoichiometric method and the other is called the catalytic method. These two methods due to the toxicity of nickel carbonyl, nickel consumption and the danger of acetylene at high temperatures and other factors, the industrialization of the existence of great difficulties.
• 4. Propylene direct oxidation methodPropylene is first oxidized to acrolein, and then further oxidized to acrylic acid. Production of acrylic esters from acrylic acid is to acrylic acid and the corresponding alcohol in the presence of ion exchange resin catalysts, in the boiling temperature of the continuous esterification reaction.
