Abstract
Se describe un producto de sevoflurano crudo que comprende niveles inaceptablemente altos de FIP, que puede ser purificado mediante la combinacion del producto de sevoflurano crudo con suficiente agua para producir una mezcla de fases multiples, destilando fraccionalmente la mezcla de fases multiples, y retirando el sevoflurano sustancialmente puro de la mezcla de fases multiples de destilacion. Se enfatiza que este extracto es proporcionado para cumplir con las reglas que requieren un extracto que permitira que un investigador u otro lector evaluen rapidamente la materia de interes de la descripcion tecnica. Esta es propuesta con el entendimiento de que no sera utilizada para interpretar o limitar el alcance o significado de las reivindicaciones anexas expedidas.
