Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. It liberates hydrogen cyanide easily, so it is used as a source of such.
The structure of a general cyanohydrin. In organic chemistry, a cyanohydrin or hydroxynitrile is a functional group found in organic compounds in which a cyano and a hydroxy group are attached to the same carbon atom. The general formula is R 2 C(OH)CN, where R is H, alkyl, or aryl.
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 (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
In the most common route, methacrylic acid is prepared from acetone cyanohydrin, which is converted to methacrylamide sulfate using sulfuric acid.This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step.
Linamarin is a cyanogenic glucoside found in the leaves and roots of plants such as cassava, lima beans, and flax.It is a glucoside of acetone cyanohydrin.Upon exposure to enzymes and gut flora in the human intestine, linamarin and its methylated relative lotaustralin can decompose to the toxic chemical hydrogen cyanide; hence food uses of plants that contain significant quantities of ...

It is commonly collected as a byproduct of the "acetone cyanohydrin route" to the commodity chemical methyl methacrylate. [1] It can also be obtained by hydrolysis of sulfamic acid in aqueous solution, which produces the salt in high purity: H 3 NSO 3 + H 2 O → (NH 4)HSO 4. It also arises by the thermal decomposition of ammonium sulfate:
