Encapsulation process for particles

Claim 1

PROCESS FOR COATING PARTICLES OF AN OXIDIZING MATERIAL HAVING AT LEAST ONE REACTIVE CHLORINE ATOM IN ITS MOLECULAR STRUCTURE COMPRISING THE STEPS OF: I. PLACING SAID PARTICLES IN SUCH A CONFIGURATION AS TO DEFINE A LAYER THEREOF HAVING A THICKNESS BETWEEN ABOUT 1/2 INCH AND ABOUT 6 INCHES, ON A PERFORATED SUPPORT. II. ADJUSTING THE HEIGHT OF A DOWNWARDLY DISPOSED SPRAYING MEANS CAPABLE OF PRODUCING A SPRAY OF LIQUID DROPLET IN A DOWNWARDLY DIVERGING PATTERN, TO A LEVEL SUCH THAT THE OUTERMOST DROPLETS OF SAID SPRAY CONTACT SAID LAYER OF PARTICLES AT THE PERIMETER THEREOF AS DEFINED BY SAID LAYER IN STATIC STATE, III. CAUSING A GAS FLOW UPWARD THROUGH SAID PERFORATED SUPPORT, THEREBY EXPANDING THE THICKNESS OF SAID LAYER AND MAINTAINING SAID PARTICLES IN SAID BED ARE COMPLETELY FORM A FLUIDIZED BED, IV. SPRAYING A SOLUTION OF A SOLIDIFIABLE FATY ACID ON SAID FLUIDIZED BED UNTIL ALL PARTICLES IN SAID BED ARE COMPLETELY COATED WITH SAID FATTY ACID, AND V. TREATING SAID FATTY-ACID COATED PARTICLES WITH AN AQUEOUS SOLUTION OF A FIXED ALKALI HYDROXIDE SELECTED FROM THE GROUP CONSISTING OF SODIUM HYDROXIDE POTASSIUM HYDROXIDE, AND CALCIUM HYDROXIDE, AND MIXTURES THEREOF, SAID TREATMENT COMPRISING A. AGIATING FATTY ACID-COATED PARTICLES IN SAID AQUEOUS HYDROXIDE SOLUTION FOR ABOUT 120 MINUTES AT TEMPRERATURE OF ABOUT 85*F TO ABOUT 130*F, AND NOT HIGHER THAN ABOUT 5*F BELOW THE MELTING POINT OF SAID FATTY ACID, THEREBY REACTING SAID HYDROXIDE WITH AT LEAST A PORTION OF SAID FATTY ACID, THE CONCENTRATION OF SAID FIXED ALKALI IN SAID SOLUTION BEGIN ABOUT 3 TO ABOUT 10 PERCENT WHEN SAID ALKALI IS SODIUM HYDROXIDE, ABOUT 10 TO ABOUT 15 PERCENT WHEN SAID FIXED ALKALI IS POTASSIUM HYDRXIDE, AND ABOUT 0.1 PERCENT WHEN SAID FIXED ALKALI IS CALCIUM HYDROXIDE, BY WEIGHT OF SAID SOLUTION.
