1-Naphthaldehyde Chemical Properties,Uses,Production

Applications

1-Naphthaldehyde is used as a reagent in the synthesis of phosphors without rare-earth elements for eco-energy lighting based LEDs. It is also used in the synthesis of 1-Naphthoic Acid and 1-Naphthalenemethanol.

Appearance

Clear Colorless to Pale Yellow Oil

Dangerous Goods Info

Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package

Chemical Properties

Yellow liquid

Uses

1-Naphthaldehyde is used in the synthesis of single-crystalline homochiral porous metal-organic frameworks (MOFs). It is also a starting material for the Canizzaro reaction to produce 1-Naphthoic acid and 1-Naphthalenemethanol.

Uses

1-Naphthaldehyde can be used to synthesize:

(S)-1-α-naphthyl-1-ethanol
N-(4-aryl)-N-(α-naphthyliden)amines
N-aryl-N-[1-(1-naphthyl)but-3-enyl]amines
naphthalene-1-carboxylic acid methyl ester

Definition

ChEBI: A naphthaldehyde with a formyl group at position 1.

Synthesis Reference(s)

Tetrahedron, 41, p. 5703, 1985 DOI: 10.1016/S0040-4020(01)91375-4

Purification Methods

Distil 1-naphthaldehyde with steam, extract the distillate into Et2O, dry (Na2SO4), filter, evaporate the filtrate and distil the residue in a vacuum. [Beilstein 7 IV 1286.]
