Abstract
Process for treating tall oil heads with alkali at elevated temperature for recovery of heads fatty acids is improved by performing a fusion cook of such heads initiated with essentially dry alkali.
Claims9
In a process for treating tall oil heads with alkali at elevated temperature to yield a reaction mixture from which water vapor and unsaponifiable materials are removed as distillate and the resulting residue of alkali metal salts of heads fatty acids is hydrated for springing therefrom heads fatty acids, the improvement which comprises:
- initiating formation of said reaction mixture with alkali metal agent of at most very low water content;
- and
- conducting said alkali treating with said alkali metal agent essentially as an alkali fusion cook.
In a process for treating tall oil heads with alkali at elevated temperature to yield a reaction mixture from which water vapor and unsaponifiable materials are removed as distillate and the resulting residue of alkali metal salts of heads fatty acids is hydrated for springing therefrom heads fatty acids, the improvement which comrprises:
- initiating formation of said reaction mixture with alkali metal agent containing less than about 10% water by weight, said initially formed reaction mixture containing not substantially more than about 12% water by weight;
- and
- conducting said alkali treating with said alkali metal agent essentially as an alkali fusion cook.
