1-HYDROXY-2-BUTANONE Chemical Properties,Usage,Production

  • Description May be synthesized from l-chlorobutan-2-one by hydrolysis or by heating the chloro compound with potassium formate in methanol; the ethyl ester may be prepared by bacterial oxidation of the corresponding glycol with Aspergillus niger.
  • Chemical Properties Colorless liquid
  • Occurrence Reported found in coffee and mushrooms.
  • Preparation From 1-chlorobutan-2-one by hydrolysis or by heating the chloro compound with potassium formate in methanol; the ethyl ester may be prepared by bacterial oxidation of the corresponding glycol with Aspergillus niger.
  • Definition ChEBI: 1-hydroxybutan-2-one is a primary alpha-hydroxy ketone that is butane-1,2-diol in which the hydroxy group at position 2 has been formally oxidised to give the corresponding ketone. It is functionally related to a butan-2-one and a butane-1,2-diol.
  • Taste threshold values Taste characteristics at 30 ppm: brown, oily and alcoholic with toasted grain notes.
