Abstract
Alkaline reacting compounds are added prior to the distillation of compounds of fatty acids with alkylolamines, or materials containing the same in order to facilitate the recovery of the free alkylolamines by suppressing amide formation. Preferably, steam and reduced pressure are employed, and any free alkylolamine may first be distilled off before adding the alkaline compounds. Results showing the effect of the addition of caustic potash on distilling with steam mixtures of oleic acid and ethanolamine under various conditions are tabulated. The extracts obtained in the removal of free fatty and naphthenic acids by means of alkylolamines from liquid animal and vegetable oils, fats and waxes and resins are particularly suitable as raw material for the process. Volatile components such as methyl ketones, and low boiling amines which are distilled with the first fractions of alkylolamines may be collected separately and the fatty acids remaining as residues may be recovered. The following fatty components are mentioned: palmitic, stearic, oleic, elaidic, hydrocarpic, chaulmougric, adipic, pimelic, ruberic, azelaic and sebacic acids and also the following alkylolamines: propanolamines, butanolamines and pentanolamines. Besides alkali and alkaline earth oxides, hydroxides and carbonates, soaps such as sodium or potassium oleate &c. may be used in the process as alkaline reacting compounds.ALSO:Compounds of fatty acids with alkylolamines, or materials containing such compounds, are distilled in presence of alkaline reacting compounds in order to facilitate the recovery of the free alkylolamines by suppressing amide formation. Fatty acids and metal soaps remain as residues. Preferably steam and reduced pressure are employed, and any free alkylolamine may first be distilled off before adding the alkaline compounds. Results showing the effect of the addition of caustic potash on steam-distilling mixtures of oleic acid and ethanolamine under various conditions are tabulated. The soaps obtained in the removal of free fatty and naphthenic acids by means of alkylolamines from animal and vegetable oils, fats and waxes and resins are particularly suitable as raw material for the process. The following fatty components are mentioned:--palmitic, stearic, oleic, elaidic, hydrocarpic, chaulmoogric, adipic, pimelic, suberic, azelaic, and sebacic acids. Alkylolamines specified are:--propanolamines, butanolamines and pentanolamines. Suitable alkaline reacting compounds are alkali and alkaline earth oxides, hydroxides and carbonates, and soaps such as sodium or potassium oleate, stearate, palmitate.
