Facts (generated by robot; please edit if you find it inaccurate)

  • A hemiketal is an alcohol and ether attached to the same carbon, along with two other carbons.
  • In a more dilute stoichiometric mixture of acetone and methanol in liquid tetrahydrofuran (THF), quantitative formation of the hemiketal is observed at pressures above 2 GPa.
  • 0, while the non color hemiketal is present at pH 4.
  • A general mechanism that is consistent with these results is one in which formation of the hemiketal is rapid and is followed or preceded by a slow step that rate limits kon.
  • If the hemiketal is a sugar, the ketal is a glycoside.
