Salicylaldehyde

Salicylaldehyde

Salicylaldehyde is an organic compound that is commonly used in the synthesis of other compounds. It is a colorless liquid that is soluble in water, alcohol, and ether. Salicylaldehyde is used in the production of dyes, perfumes, and flavoring agents. It is also used in the preparation of coumarin, which is used in the perfume industry.

Chemical Properties

Salicylaldehyde is a phenolic aldehyde with the chemical formula C7H6O2. It has a strong, sweet odor and is a colorless to pale yellow liquid. It is soluble in water, alcohol, and ether. Salicylaldehyde is a weak acid and can form a dimer when concentrated.

Production

Salicylaldehyde is produced from phenol through the Riemer-Tiemann reaction. This involves the reaction of phenol with chloroform in the presence of sodium hydroxide. The resulting product is then hydrolyzed to produce salicylaldehyde.

Uses

Salicylaldehyde is used in the synthesis of other organic compounds. It is used in the production of dyes, perfumes, and flavoring agents. It is also used in the preparation of coumarin, which is used in the perfume industry. In addition, salicylaldehyde is used as a laboratory reagent.

Safety

Salicylaldehyde is a skin and eye irritant. It can cause respiratory tract irritation if inhaled. It is recommended to use proper personal protective equipment when handling salicylaldehyde.
