Definitions

  • the invention relates to acidic aqueous iodine concentrates wherein iodine in the presence of concentrated aqueous hydroxyacetic acid, is solubilized in the hydroxyacetic acid by means of a water soluble iodide (I-) in an amount equal to at least 50% by weight based on the weight of iodine.
  • I- water soluble iodide
  • an aqueous acidic iodine concentrate having these advantages can be prepared, utilizing hydroxyacetic acid as the acidifying agent, and supplying iodine in the form of an aqueous iodine-iodide solution in which the iodide (1"), present in an amount equal to at least 50% by Weight, based on the weight of iodine, acts to solubilize the iodine in the hydroxyacetic acid in all practical proportions. While amounts of iodide slightly less than 50% by weight of the iodine can sometimes be employed, the important factor is that this amount is suflicient to solubilize the iodine in the hydroxyacetic acid.
  • Amounts of iodide in substantial excess of 50%, based on the weight of the iodine provide no special advantage with respect to iodine solubility in the concentrate.
  • the proportion of iodide of about 50% by weight, based on the weight of iodine, and suflicient to solubilize the iodine in the hydroxyacetic acid should be considered as a minimal preferred proportion.
  • the solubilizing eifect of iodide on iodine in an acidic aqueous concentrate appears to be a special eifect peculiar to concentrates in which the acidifying agent is hydroxyacetic acid.
  • Phosphoric acid has been widely used as an acidifying agent for detergent-iodine formulations.
  • Phosphoric acid is quite unsuited for use in an acidic aqueous iodine concentrate of the type herein described. It has been found, for example, that in a 50% phosphoric acid solution containing as high as 15% iodide (1") only 5% iodine can be solubilized. In contrast to this, 50% of hydroxyacetic acid can solubilize over 15% of iodine with as little as 7.5% iodide present. At higher acid concentrations, the difference in behavior is even more striking.
  • the iodide in the new aqueous acidic iodine concentrates can be in the form of any water soluble iodide, such as alkali metal iodides, hydriodic acid, and the like, with hydriodic acid being preferred.
  • Example 1 will serve to show how typical acidic aqueous iodine concentrates in accordance with the present invention can be prepared, but it is to be under- Example A number of concentrates were prepared by adding to quantities of commercial concentrated (70%) hydroxyacetic acid, aqueous iodide-iodine solutions containing 50% by weight iodine and either 25% by weight of hydriodic acid or 29.5% sodium iodide (in which the proportion of iodide (I-) is approximately 50% based on the weight of iodine), and other aqueous iodide-iodine solutions in which the proportion of iodide (I) to iodine is varied above and below 50%.
  • Table A shows the compositions of a number of typical satisfactory concentrates
  • Table B shows the compositions of closely related, but unsatisfactory concentrates:
  • concentrates most suitable for use in preparing detergent-iodine formulations are those which contain about 20 to 50% hydroxyacetic acid and 10 to 25% iodine, with the iodide (1) in each instance being equal to at least 50% by weight based on the weight of iodine.
  • An acidic aqueous iodine concentrate consisting essentially of an aqueous solution of hydroxyacetic acid, iodine and a water soluble iodide, with the amount of iodide (I-) being equal to at least one-half the amount by Weight of available iodine and sufficient to solubilize the iodine in said hydroxyacetic acid, said concentrate containing about 5 to 65% by Weight of hydroxyacetic acid and 5 to 45% by Weight of available iodine.
