Applicazioni

Ethyl formate is used as a solvent for cellulose nitrate, cellulose acetate, greases and oils. It is also used as a flavor for lemonade and essences. It is involved in the fumigation of dried fruits, as an alternative to methyl bromide.

Note

Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with bases and oxidizing agents.

Letteratura

Many illustrations of use in formylation of carbanions are given in Organic Syntheses: For more recent examples, see: Org. Synth. Coll., 6, 590, Note 1 (1988); Org. Synth. Coll., 9, 180 (Note 4), 239, 548 (1998).

ɑ-Formylation of the dilithio derivatives of carboxylic acids, followed by facile decarboxylation, provides an indirect conversion to the corresponding aldehydes: Tetrahedron Lett., 699 (1970); 603 (1974).

Amines readily give N-formyl derivatives, more easily cleaved by hydrolysis than N-acetyl: Can. J. Chem., 60, 3055 (1982); for an example (L-valinol), see: Org. Synth. Coll., 8, 204 (1993).
