Abstract
Official abstract text for this publication.
An improved method for preparing squalene from a squalene-containing composition, said method comprising the steps of (a) a purification distillation carried out at a temperature T 1 ; (b) a denaturing distillation carried out at a temperature T 2 ; wherein steps (a) and (b) may be performed in either order; T 1 and T 2 are sufficient to cause squalene to boil; T 2 >T 1 ; and T 2 >200° C.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing squalene suitable for pharmaceutical use in a vaccine which comprises subjecting fish oil comprising squalene to: (i) a purification distillation carried out at near vacuum; and (ii) a denaturing distillation carried out at a temperature greater than or equal to 210° C. at a pressure of 0.8 to 5.0 mmHg, wherein the temperature in the denaturing distillation exceeds the temperature in the purification distillation; and whe…
