| abstract |
SUBSTANTIALLY DRY PULBERULENT SOLID COMPOSITIONS ARE PROVIDED WHICH COMPRISE AN EFFECTIVE AMOUNT OF CHLORINE DIOXIDE SOLUTIONS, SUCH AS THE CHLORINE DIOXIDE SOLUTIONS STABLIZED WITH PEROXY AND PERCARBONATE COMPOUNDS, OR A LIKE SOLUTION SUCH AS THE ALKALINE CHLORINE SOLUTIONS, ADSORBED ON A BASIC-REACTING ADSORBENT, SUCH AS SYNTHETIC CALCIUM SILICATE. THESE COMPOSITIONS WILL YIELD GASEOUS CHLORINE DIOXIDE UPON ACIDIFICATION TO A PH OF LESS THAN ABOUT 6. PREFERRED ACIDIFYING AGENTS INCLUDE POWDERED HYDRATED CITRIC ACID OR DRY ACID REACTING ADSORBENTS SUCH AS SILICATES HAVING AN AQUEOUS SOLUTION OF AN ACIDIC COMPOUND, SUCH AS FERRIC CHLORIDE OR SULFURIC ACID, ADSORBED THEREON. THE COMPOSITIONS CAN BE USED FOR THE PRESERVATION OF FRUITS AND VEGETALBES BEING SHIPPED OR STORED. |
