It is used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium cyanide: [8] (CH 3) 2 C(OH)CN + LiH → (CH 3) 2 CO + LiCN + H 2. In 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 ...
Acetone cyanohydrin, (CH 3) 2 C(OH)CN is the cyanohydrin of acetone. It is generated as an intermediate in the industrial production of methyl methacrylate . [ 3 ] In the laboratory, this liquid serves as a source of HCN, which is inconveniently volatile. [ 4 ]

In transhydrocyanation, an equivalent of HCN is transferred from a cyanohydrin, e.g. acetone cyanohydrin, to another activated HCN acceptor. The transfer is an equilibrium process, initiated by base. The reaction can be driven by trapping or a superior acceptor, such as an aldehyde. [9]
Hydrogen cyanide (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N.It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).
LiCN is produced from the reaction of lithium hydroxide and hydrogen cyanide. A laboratory-scale preparation uses acetone cyanohydrin as a surrogate for HCN: [5] (CH 3) 2 C(OH)CN + LiH → (CH 3) 2 CO + LiCN + H 2
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone ( R−C(=O)−R' ). It is a colorless, highly volatile , and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops .
