Emulsin also decomposes amygdalin directly into these compounds without the intermediate formation of mandelic nitrile glucoside.
The enzyme maltase decomposes it into glucose and mandelic nitrile glucoside; the latter is broken down by emulsin into glucose, benzaldehyde and prussic acid.
It also unites directly with hydrocyanic acid to form thenitrile of a-oxyisobutyric acid.
The true nitrile of malonic acid is methylene cyanide, CH2(CN)2, which is obtained by distilling a mixture of cyanacetamide and phosphorus pentoxide.
The half nitrile of malonic acid is cyanacetic acid, CN.
When it has completely disappeared, the system will be represented by the point c', where the molecular concentration of nitrile is now 75 per cent.
If heat be added, the solid nitrile will disappear, and there will be left the univariant system, consisting of two liquid phases and vapour.
We have here, therefore, the phenomenon of melting under the solution as in the case of succinicnitrile and water (p.
If to the system ice--water at 0deg succinic nitrile is added, the temperature will fall; and continued addition of the nitrile will lead at last to the cryohydric point b (Fig.
As a matter of fact, continued addition of nitrile and addition of heat will cause an increase in the amount of the liquid phase containing excess of nitrile (i.
If the temperature be now raised so as to cause the disappearance of the ice, and the addition of nitrile be continued, the concentration of the nitrile in the solution will increase as represented by the curve bc.
Since b is the lowest temperature at which liquid can exist in stable equilibrium with solid, ice and succinic nitrile can be mixed in any proportions at temperatures below b without undergoing change.
Between b and c succinic nitrile will be dissolved until the concentration reaches the value on the curve bc, corresponding to the given temperature.
From the figure it will be easy to see what will be the result of bringing together succinic nitrile and water at different temperatures and in different amounts.
Most hydrolyzing agents break the molecule first at (1), yielding one molecule of glucose and one of mandelo nitrile glucoside (see page 77).
Similarly, it is possible to convert mandelo nitrile into mandelic acid by splitting off the nitrogen to form a COOH group, instead of splitting off the HCN group leaving benzaldehyde.
This process is the exact reverse of the nitrile synthesis, described above.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "nitrile" in a variety of sentences. We hope that you will now be able to make sentences using this word.
