Reducing agent. | [Preparation]
One method of preparation is
the controlled alcoholysis of NaAlH4 with 2-
methoxyethanol:
NaAlH4+2 CH3OCH2CH2OH→NaAlH2(OCH2CH2OCH3)2
+H2
On an industrial scale, however, it is produced
by direct synthesis from sodium, aluminum, and
2-methoxyethanol at 140 – 155 C in an atmosphere of hydrogen at at least 7 MPa:
Na+Al+2 CH3OCH2CH2OH→NaAlH2(OCH2CH2OCH3)2
The quantity of hydrogen required is generated in situ by the reaction of sodium and aluminum
with the alcohol. SDMA(Sodium bis(2-methoxyethoxy)aluminiumhydride) is marketed as a 70 %
solution in toluene (r = 1.036 g/cm3
) under the
name Vitride (Hexcel). | [General Description]
Red-Al? sodium bis(2-methoxyethoxy)aluminum hydride [NaAlH2(OCH2CH2OCH3)2] is used as a versatile reducing agent in organic synthesis. It is used to reduce:
- Aldehydes, ketones, esters, and anhydrides to primary alcohols.
- Ketoximes and aldoximes to primary amines.
- Cyclic compounds such as lactones and epoxides to diols.
It is also used as a catalyst in the ring-opening polymerization reactions. |
