Pre-Reduction of Carbonyl Groups with Lithium Aluminum Hydride

1 Pre-Reduction of Carbonyl Groups with Lithium Aluminum Hydride (Note I) [Pg.438]

The following procedure is that described by Marton and Adler (1963). Finely powdered LiAlH4 (4.4 g) is suspended in 50ml of absolute dioxane in a hydro- [Pg.438]

The solid material obtained after centrifuging the acidified mixture (material A) is further treated with dilute hydrochloric acid and the lignin residue thus obtained is centrifuged off, washed with water, dried, and purified by repreciptitating its dioxane solution as described above yield 1.2g. There is no apparent difference between the two lignin fractions. [Pg.439]
