Acetone | Definition of Acetone by Merriam-Webster

b) Comparative studies on the kinetics of cyanide formation from acetonitrile, as well as of conjugation to thiocyanate and its elimination, should be conducted.

Synthesis of β-hydroxy nitriles and 1,3-amino alcohols from epoxides using acetone cyanohydrin …

Some chemical properties of other cyanides are given in Table 2. Copper cyanide is a white to cream-coloured solid. Its common name is cuprous cyanide, and its synonym is cupricin. Potassium silver cyanide occurs as white crystals; its common synonym is potassium dicyanoargentate. It is sensitive to light. Sodium ferrocyanide decomposes at 435 °C, forming sodium cyanide.

Acetonitrile is used as a common laboratory solvent for recrystallizing various chemicals and is widely used as a solvent in HPLC analysis.

Urinary acetonitrile was detectable for 4 days after dosing, whereas free and combined cyanide were detectable until 11 days, at which time the animals were sacrificed.

They all suggested a metabolic pathway in which acetonitrile is bio-transformed by cytochrome P-450 monooxygenase system initially to cyanohydrin, which then spontaneously decomposes to hydrogen cyanide and formaldehyde as shown in Fig.

This CICAD on hydrogen cyanide and cyanides (human health aspects) was prepared by Prof. Fina Petrova Simeonova and Dr Lawrence Fishbein, based principally on the Agency for Toxic Substances and Disease Registry toxicological profile for cyanide (ATSDR, 1997) and the Joint FAO/WHO Expert Committee on Food Additives document on cyanogenic glycosides (JECFA, 1993). The source documents and a description of their review processes are presented in Appendix 1. A comprehensive literature search of several online databases was performed in October 2002 to identify any relevant references published subsequent to those cited in the source documents. This CICAD was first discussed at the 10th Final Review Board meeting, held in Monks Wood, United Kingdom, on 16–19 September 2002. Following revision, it was discussed again and approved as an international assessment at the 11th Final Review Board meeting, held in Varna, Bulgaria, on 8–11 September 2003. Participants at the 10th and 11th Final Review Board meetings are listed in Appendices 2 and 3. The drafts discussed at these meetings were peer reviewed before the meetings; information on the peer review process is presented in Appendix 4. The International Chemical Safety Cards on hydrogen cyanide, sodium cyanide, potassium cyanide, calcium cyanide, cyanogen, cyanogen chloride, acetone cyanohydrin, and potassium ferricyanide, produced by the International Programme on Chemical Safety (IPCS, 1999a,b, 2000b, 2001, 2002a,b,c,d), have also been reproduced in this document.

There is a biological example of this reaction

However, the rate of acetonitrile biotransformation into cyanide by liver microsomal preparation obtained from cobalt-heme-treated rats was 13% of controls, while the total cytochrome P-450 content was reduced by only 41% compared to the controls.
