Abstract
Provided herein are methods of making acetonitrile from (e.g., biologically produced) precursors. The methods herein may be less carbon intensive and produce fewer toxic byproducts than traditional methods. Also provided herein are acetonitrile compositions, such as prepared by the methods provided herein.
Claims52
A method of making an acetonitrile composition, the method comprising:
- (a) providing a biologically produced acetonitrile precursor;
- (b) purifying the biologically produced acetonitrile precursor;
- (c) reacting the biologically produced acetonitrile precursor with a nitrogen source and a catalyst to provide crude acetonitrile;
- and
- (d) purifying the crude acetonitrile to provide the acetonitrile composition, wherein the reacting produces no more than 20 wt % of organic products other than acetonitrile, and wherein the acetonitrile composition comprises less than 2 wt % of impurities.
A method of making an acetonitrile composition, the method comprising:
- (a) providing a biologically produced acetonitrile precursor;
- (b) purifying the biologically produced acetonitrile precursor;
- (c) reacting the biologically produced acetonitrile precursor with a nitrogen source and a catalyst to provide crude acetonitrile;
- and
- (d) purifying the crude acetonitrile to provide the acetonitrile composition, wherein the method does not generate hydrogen cyanide.
