Continuous process for preparing alkali metal dispersions and apparatus
Abstract
Abstract A PROCESS FOR PREPARING CONTINUOUSLY A DISPERSION IN AN INERT ORGANIC DILUENT OF A FINELY-DIVIDED ALKALI METAL, SUCH AS SODIUM, SUBSTANTIALLY UNIFORM IN PARTICLE SIZE AND ALKALI METAL CONCENTRATION IS PROVIDED WHEREIN A MOLTEN ALKALI METAL IS DISPERSED IN AN INERT ORGANIC DILUENT WITH A DISPERSING AID WHICH IS SOLUBLE IN THE INERT DILUENT, AND IF NECESSARY, A STABILIZING AGENT, BY SUBJECTING THE MOLTEN ALKALI METAL TO HIGH SHEAR FORCES, AND FORMING ALKALI METAL PARTICLES LESS THAN AND GREATER THAN A PREDETERMINED MEDIAN. THE COARSE PARTICLES OF MOLTEN ALKALI METAL AT OR ABOVE THE MEDIAN SIZE ARE ALLOWED TO SETTLE OUT, AND THE SUPERNATANT FINE PARTICLES OF MOLTEN ALKALI METAL AT OR BELOW THE MEDIAN SIZE ARE DRAWN OFF. THE COARSE PARTICLES ARE CONTINUOUSLY RETURNED TO THE ZONE OF HIGH SHEAR TO FURTHER REDUCE THEIR SIZE, AND ALKALI METAL IS CONTINUOUSLY ADDED TO THE ZONE, WHILE THE DISPERSION OF FINE PARTICLES OF ALKALI METAL HAVING A SIZE AT OR BELOW THE MEDIAN, AND SUBSTANTIALLY UNIFORM IN ALKALI METAL CONCENTRATION IS CONTINUOUSLY WITHDRAWN.
