An easily amenable method is presented to produce acetone cyanohydrin on mole scale (output 39 g/h), using a continuous flow system to overcome the high risks associated with the large-scale use of hydrogen cyanide.

Nitrile/cyanide hydrolysis is of importance from the perspective of organic chemistry, especially, prebiotic chemistry. Herein we report that cyanohydrins, generated by the reaction of cyanide with β-keto acids and γ-keto-alcohols, spontaneously hydrolyze

A minimal cell can be thought of as comprising informational, compartment-forming and metabolic subsystems. To imagine the abiotic assembly of such an overall system, however, places great demands on hypothetical prebiotic chemistry. The perceived differences and incompatibilities between these subsystems have led to the widely held assumption that one or other subsystem must have preceded the others. Here we experimentally investigate the validity of this assumption by examining the assembly of various biomolecular building blocks from prebiotically plausible intermediates and one-carbon feedstock molecules. We show that precursors of ribonucleotides, amino acids and lipids can all be derived by the reductive homologation of hydrogen cyanide and some of its derivatives, and thus that all the cellular subsystems could have arisen simultaneously through common chemistry. The key reaction steps are driven by ultraviolet light, use hydrogen sulfide as the reductant and can be accelerated by Cu(I)-Cu(II) photoredox cycling.

The present invention relates in general terms to a process for preparing acetone cyanohydrin, comprising as steps: A. contacting acetone and hydrocyanic acid in a reactor to give a reaction mixture, the reaction mixture being circulated, to obtain acetone cyanohydrin;B. cooling at least some of the reaction mixture by flowing it through a cooling region of a cooler, the cooler including one cooling element or at least two cooling elements;C. discharging at least a portion of the acetone cyanohydrin obtained from the reactor, the volume of the cooling region of the cooler based on the total internal volume of the cooler being greater than the volume of the cooling element or of the at least two cooling elements of the cooler, to a process for preparing an alkyl methacrylate, to a process for preparing a methacrylic acid, to an apparatus for preparing alkyl methacrylates, to a process for preparing polymers based at least partly on alkyl methacrylates, to the use of the alkyl methacrylates obtainable from the process according to the invention in chemical products, and to chemical products based on the alkyl methacrylates obtainable by the processes according to the invention.
