2-Naphthalene formaldehyde has the following properties:
Appearance: Colorless or light yellow solid.
Odor: Has a special fragrance.
Solubility: Slightly soluble in water, soluble in organic solvents such as alcohols and ethers.
Chemical synthesis: can be used as an intermediate or raw material for the synthesis of other organic compounds, such as 2-naphthoic acid, naphthone, etc.
Spices and essence: Its special fragrance can be used in the production of perfume and essence.
Dyes: Can be used for the synthesis of dyes.
The main methods for preparing 2-naphthaldehyde include:
Reaction between naphthalene and formaldehyde: naphthalene reacts with formaldehyde under alkaline conditions to form 2-naphthaldehyde through condensation reaction.
Oxidation of naphthalene: Naphthalene is oxidized with oxygen or hydrogen peroxide in the presence of a catalyst to produce 2-naphthaldehyde.
Pay attention to personal protection: wear chemical protective goggles, chemical protective clothing, gloves, etc.
Avoid inhalation: Keep away from sources of fire or high temperature areas during operation and ensure good ventilation.
Avoid contact with skin and eyes: If accidentally touched, rinse immediately with plenty of water.
Storage: Store in a dry, cool, ventilated place, away from sources of fire and oxidants.
