In the laboratory, this liquid serves as a source of HCN, which is inconveniently volatile. [4] Thus, acetone cyanohydrin can be used for the preparation of other cyanohydrins, for the transformation of HCN to Michael acceptors, and for the formylation of arenes. Treatment of this cyanohydrin with lithium hydride affords anhydrous lithium cyanide:
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 ...

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).
Ethylene oxide easily reacts with hydrogen cyanide forming ethylene cyanohydrin: (CH 2 CH 2)O + HCN → HO–CH 2 CH 2 –CN. A slightly chilled (10–20 °C) aqueous solution of calcium cyanide can be used instead of HCN: [38] 2 (CH 2 CH 2)O + Ca(CN) 2 + 2 H 2 O → 2 HO–CH 2 CH 2 –CN + Ca(OH) 2. Ethylene cyanohydrin easily loses water ...
Removal of cyanide from cassava in Nigeria. Cyanides are produced by certain bacteria, fungi, and algae.It is an antifeedant in a number of plants. Cyanides are found in substantial amounts in certain seeds and fruit stones, e.g., those of bitter almonds, apricots, apples, and peaches. [5]
The Spanish name Llanero translates as "horse of the plains". [1] The DAD-IS database and the University of Oklahoma Encyclopedia (2007) [1] refer to the breed as Llanero (without diacritical mark), while CAB International, [2] the Delachaux guide [3] and researchers from the teams of E. G. Cothran [4] and J. L Canelón [5] refer to it as "Venezuelan Criollo".
It has been shown to be detrimental to the viability of skin grafts in horses, [114] and only minimal effects on horses with induced endotoxemia. [115] HBOT is considered very safe, with few contraindications, although its cost and availability make it less widely used than most other forms of treatment.
