Applicazioni

Sodium formate is used in analytical chemistry to precipitate noble metals. It is used for tanning leather, for dyeing and printing fabrics. It acts as an electroplating agent, an acidulant in the textile industry, a reducing agent, a mordant, a complexing agent. Further, it is used in photographic fixing baths. In addition, it is used as a buffering agent for strong mineral acids and food additive.

Note

Hygroscopic. Incompatible with strong oxidizing agents, strong acids. Moisture sensitive

Converts Grignard reagents to aldehydes in excellent yields: Tetrahedron Lett., 25, 1843 (1984). Lithium formate may also be used.

Under phase-transfer conditions converts primary alkyl chlorides to alcohols via the formate esters: Synthesis, 763 (1986).

Reaction with acetyl chloride gives the useful formylating agent, formic acetic anhydride. For details, including isolation by distillation, see: Org. Synth. Coll., 6, 8 (1988); review: Tetrahedron, 46, 1081 (1990).

Reduces amine oxides to amines under mild conditions: Chem. Lett., 1517 (1985).

Can be used as a hydrogen donor in catalytic transfer hydrogenation reactions. More active hydrogen donor than formic acid in hydrogenolysis of aryl chlorides. For a comparative mechanistic study of formic acid and formate salts in this reaction, see: J. Org. Chem., 60, 1347 (1995). See also Ammonium formate, A10699 .
