Lieben and Rossi, Ann., 1 58, 150 (1871)) t o the corresponding alcohol, pentanol-1. The constitution of the body follows from the method of preparation. Methods of Formation.-a. By reduction of n-kaleric aldehyde with sodium amalgam (Lieben and Rossi, Ann., 159, 70 (1871)). b. By reduction of ethyl valerate with sodium ethylatc (Bouevalt and Blanc, French Pat. through Centrut, i6,2, 1700 (1905)). c.
