Common Name | Acetone cyanohydrin |

Description | Acetone cyanohydrin, also known as 2-methyllactonitrile, belongs to the class of organic compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ). Crushing the tubers releases these compounds and produces acetone cyanohydrin. It is used as a surrogate in place of HCN, as illustrated by this synthesis of lithium cyanide:(CH3)2C(OH)CN + LiH → (CH3)2CO + LiCN + H2In transhydrocyanation, an equivalent of HCN is transferred from acetone cyanohydrin to another acceptor, with acetone as byproduct. The transfer is an equilibrium process, initiated by base. Treated with sulfuric acid give the sulfate ester of the methacrylamide, methanolysis of which gives ammonium bisulfate and methyl methacrylate. Acetone cyanohydrin is an extremely weak basic (essentially neutral) compound (based on its pKa). Acetone cyanohydrin is classified as an extremely hazardous substance in the US Emergency Planning and Community Right-to-Know Act. Acetone cyanohydrin exists in all living organisms, ranging from bacteria to humans. Outside of the human body, Acetone cyanohydrin has been detected, but not quantified in, several different foods, such as oregon yampahs, lowbush blueberries, common sages, grapefruits, and chicories. This could make acetone cyanohydrin a potential biomarker for the consumption of these foods. It liberates hydrogen cyanide easily, so it is used as a source of such. Acetone cyanohydrin is a potentially toxic compound. Alternatively, a simplified procedure involves the action of sodium or potassium cyanide on the sodium bisulfite adduct of acetone prepared in situ. |
