Potassium chlorate density

Potassium iodate [7758-05-6] KIO, mol wt 214.02, 59.30% I, forms white, odorless crystals or a crystalline powder. It has a density 3.98 g/mL and mp of 560°C with partial decomposition. Potassium iodate is rapidly formed when potassium iodide is fused with potassium chlorate, bromate, or perchlorate. The solubihty in water is 9.16 g/100 g H2O at 25°C and 32.2 g/100 g H2O at 100°C. KIO is extensively used as an oxidizing agent in analytical chemistry and as amaturing agent and dough conditioner (see Bakery processes and leavening agents). 

Oxidation of polyethylene by sulphuric acid and potassium chlorate [9,10] improves its adhesiveness. The free energy of adhesion of the polymer is found to increase linearly with the surface density of the hydrophyl-lic sites created by oxidation. 

Cartridges containing only potassium chlorate were transported in safety to the site, where they were dipped for a definite time into kerosene just before use. Miedziankit was also manufactured by soaking potassium chlorate cartridges with kerosene in the explosive factory. Kerosene with an ignition temperature above 30°C was employed, to render the product safe for rail transport. According to T. Urbanski [76] the rate of detonation of Miedziankit is 3000m/sec in an iron pipe at a density of 1.7. 

In the last-named case the reaction is dangerously explosive and should only be carried out with small quantities of the reagents. Ozone is also formed during the decomposition by heat of potassium chlorate, and by the action of nitric acid, preferably of density 1-33, on ammonium persulphate1 carefully warmed up to 65° to 75° C. The liberated gases are washed with caustic-potash solution and contain from 3 to 5 per cent, of ozone. 

In 1897 Thomsen 1 employed the aluminium method already cited (p. 43), and determined the weight of a normal litre of hydrogen to be 0 089947 0 000012 gram, and the corresponding weight of oxygen, prepared from potassium chlorate, to be 1 42906 0 00004 grams. The ratio of the densities is... 

Low density polyethylene film (PE), known under the commercial name "Polyane" and produced by "La Cellophane" was used in this work. Its thickness was 100 ym and its density was 0.929 g/cm. It melts between 109-112°C. The PE samples were extracted with acetone, dried under reduced pressure and oxidized by immersion in the mixture of sulfuric acid (sq.gr. 1.84 pure grade) and potassium chlorate (reagent grade). The oxidation was performed at room temperature and the percentage of potassium chlorate in the mixture for each set of experiments was varied. Thus, different degrees of oxidation could be obtained. After oxidation PE samples are rinsed several times with triple distilled water and dried in a desicator under reduced pressure. 

A third method to produce these so-called structured particles is to first form a particle with higher cross-link density and then lower the cross-link density in the center of the particle. Cross-linked polymers made in the presence of oxidizing agents such as sodium or potassium chlorate have shown improvements in absorbency under load and swelling capacity after a high temperature heating step (27) wherein a portion of the polymer chains in the particle center are cleaved through the action of the oxidizers.
