    Processing oil used to treat insoluble sulfur can lead to reversion of the sulfur to the soluble form even when it has been stabilized. This reversion is inhibited by mixing iodine with the oil. An amount of oil from 1 to 200 milligrams per liter of oil can be used. The insoluble sulfur product may contain from 1 to 30% of the oil based on the total weight of the product.

    They are used for control, the second part is treated with oil, and the third part is treated with oil, to which is added 5slot in the amount of 15 mg / l. The processing of the oil consists in placing 5 g of the core in a crucible and adding 2 O of oil. The control sample is also placed in a crucible; however, no oil is added to it; each crucible is sealed in a cop, which is placed in a thermostat for 4 hours at 60 ° C. After that, the sample is removed from the thermostat, washed with carbon disulfide to remove sulfur The amount of insoluble sulfur in each sample is determined. The results are shown in Table. 1. Yves of Table 1 shows that the treatment with maol O1: it has a destabilizing effect on sulfur, and that chlorine does not ingest this destabilizing tendency of the oil. Example 2. Procedure 1 is repeated to determine the effect of treating with mala bromine or iodine on the tendency of the oil to destabilize sulfur. The results are shown in Table. 2. Sulfur, treated with maspam, does not contain either bromine or iodine, less stable. wen, than sulfur, did not add any oil to the surface. Adding bromine to the oil does not have a noticeable effect on the tendency of the oil to destabilize sulfur. Sulfur treated with an oil containing iodine has the same stability as control samples that were not previously treated with oil. 9 44 Destabilizing oil tendencies are substantially neutralized with iodine. This suggests that iodine effectively inhibits the effect of increasing the rate of reverse conversion of insoluble sulfur to soluble sulfur, which is provided by an oil treatment. Example 3. The following examples are used to determine the effect that treatment with oil and iodine has on the tende to oil destabilize sulfur. The results are shown in Table. 3. These results indicate that treatment with oil accelerates the degree of reverse transformation of insoluble sulfur, however, the addition of iodine to this oil inhibits the tendency to accelerate the degree of reverse transformation of insoluble sulfur. The action of both oil and iodine is better manifested here, since in this example unstabilized sulfur was used, whereas in the previous examples stabilized sulfur was used. Example 4: The same procedure as in the previous Example Xj is used to determine the effect of oils, which are treated with different amounts of iodine, on the stability of stabilized sulfur. The results are shown in Table. 4. These results show that as small as 5 mg of iodine per liter of oil significantly affects the tendency of the oil to increase the rate of reverse conversion of insoluble sulfur.
