Benzaldehyde

Benzaldehyde is a colorless or light yellow volatile oily liquid with a strong refractive index. It has a bitter almond smell and an aromatic smell when burned. Miscible with ethanol, ether, volatile oil and fixed oil, slightly soluble in water. It is an important chemical raw material, used to make lauric aldehyde, lauric acid, phenylacetaldehyde and benzyl benzoate, etc., and also used as spices. Benzaldehyde is the main component of bitter almond oil extract and can also be extracted from apricots, cherries, laurel leaves, and peach stones. This compound is also found in nuts and nuts in a glycoside-bound form (Amygdalin).

acetaldehyde

Acetaldehyde is an aldehyde, also known as acetaldehyde. It is a colorless, easy-flowing liquid with a pungent odor. It has a melting point of -121°C, a boiling point of 20.8°C, and a density of less than 1000 kg/cubic meter. It is miscible with some organic substances such as water and ethanol. It is flammable and volatile, and steam and air can form explosive mixtures with an explosion limit of 4.0% to 57.0% (volume).

The reaction principle of benzaldehyde and acetaldehyde

Benzaldehyde and acetaldehyde can react. The reaction principle is as follows:

1. The bond between the alpha hydrogen of acetaldehyde and the alpha carbon is broken, and the alpha carbon of acetaldehyde is added to the carbon connected to the oxygen of benzene formaldehyde. Because the first step in aldol condensation is the departure of alpha hydrogen, benzene formaldehyde does not have alpha hydrogen.

2.at When reacting in concentrated alkali, a disproportionation reaction occurs, benzaldehyde is reduced to form benzyl alcohol, and formaldehyde is oxidized to form formic acid.
