The addition of hydrogen cyanide to isophorone for the production of 1,3,3-trimethyl-5-oxo-carbonitrile is successful when using lithium hydroxide in an amount from 0.005 to 5 mole % at 100 to 160°C with a high yield and with a substantially higher space time yield than was possible with the use of other alkaline reacting alkali compounds.
