Process for dispensing tributyle and/or butanole by liquid-phase chromatography.

摘要

Determination of tributyl phosphate (TBP) and/or of butanol by liquid phase chromatography. A sample of an organic solution containing TBP and/or butanol is injected into a column (1) filled with a polar solid stationary phase, for example silica grafted with NH2 groups, and through which passes a mobile liquid phase of apolar nature, for example a mixture of heptane and ethyl acetate, originating from (9), and the TBP and/or the butanol leaving the column is detected by refractometry at (11). <IMAGE>
