Definitions
- the organic mixture is treated with an effective amount of an additive or combination of additives including sulfurous acid, a salt of sulfurous acid, or an alkali hydroxide.
- a salt of sulfurous acid is meant to include a salt of pyrosulfurous acid, such as a metabisulfite.
- the treatment is typically conducted at a temperature in the range of about 60 to about 160 degrees C and may last for about 10 to about 90 minutes, typically greater than 30 minutes.
- the organic mixture should be stirred during treatment to facilitate good mixing of the additive(s) with the cyclohexenone.
