Methoxypropionaldehyde (381-73-7) is a colorless liquid with a sharp, pungent odor. It is miscible in water and slightly miscible in alcohols. It is a key intermediate in the production of industrial chemicals, including isobutene, 2-methyl-2-butene and tert-butanol. It is also used in the production of hydrogenation catalysts and lubricating oils.

Methoxypropionaldehyde is produced by the catalytic hydroformylation of propylene, using a cobalt-containing catalyst and poisoning agents such as acetic acid. The reaction product is separated by distillation. The degradation product of methoxypropionaldehyde, methoxyacetaldehyde, is also a useful product.

Methoxypropionaldehyde is a highly reactive aldehyde, and is especially sensitive to light and oxygen. It easily polymerizes, creates solid particles and deposits on glass and process equipment, further degrading the product quality. This can be prevented by using an inert atmosphere and stabilizers such as hydroquinone and hydroquinone monomethyl ether.

The industrial applications of methoxypropionaldehyde include the manufacture of isobutene, 2-methyl-2-butene and tert-butanol, which can be used in the production of gasoline, jet and diesel fuels, LPG, surfactants, detergents, and plasticizers. It is also used in the manufacture of lubricating oils and hydrogenation catalysts. It can be used as a specialty solvent in the coatings and cleaning industry.

Methoxypropionaldehyde is toxic and corrosive, and should be handled with care. Contact with eyes and skin should be avoided, and appropriate protective clothing should be worn when handling the material. Proper ventilation should be maintained to ensure proper concentration and existence in the lab.
