A detailed account <strong>of</strong> the "Metallic Glycer-<br />
oxidee. Metallic Glycerinates, <strong>and</strong> Esters"<br />
may be foiind in Vol I <strong>of</strong> Lewkowitsch, Fifth<br />
Ed., Pages 261 to 262.<br />
<strong>Glycerol</strong> dissolves caustic alkalies,<br />
alkaline earths, <strong>and</strong> lead oxide to form<br />
chemical compounds. (Chevreul.) Lime, strontia,<br />
<strong>and</strong> baryta are precipitated nearly completely<br />
from such solutions by carbon dioxide, a small<br />
quantity only <strong>of</strong> the earths escaping precip-<br />
itation. In the presence <strong>of</strong> caustic alkalies,<br />
glycerol also dissolves ferric oxide, cupric<br />
oxide, <strong>and</strong> bismuth oxide, owing to the form-<br />
ation <strong>of</strong> soluble metallic glyceroxides.<br />
However the following oxides are reduced to<br />
metals when heated with alkaline glycerol<br />
solution. (Bullenheimer.<br />
