Methods for making XF•nH2O2 compounds

A method of making a substantially dried compound having the general formula KF.nH2O2 wherein n is an integer from 1 to 3, said method comprising:

• (1) preparing a feed solution comprised of:
• (i) a fluid carrier component, (ii) a KF composition, (iii) hydrogen peroxide (H2O2), and (iv) potassium bifluoride (KHF2);
• (2) atomizing a portion of the feed solution as it enters a desiccation/evaporation chamber;
• (3) creating a fluid-bed of individual particles in the desiccation/evaporation chamber in order that the atomized portion of the feed solution entering said chamber coats the outside surfaces of said individual particles;
• (4) passing a pre-heated gas stream through the desiccation/evaporation chamber such that said pre-heated gas stream:
• (i) entrains feed solution-coated individual particles of the fluid-bed;
• (ii) drives off the fluid carrier component of the feed solution and thereby producing individual fluid-bed particles that are coated with a layer of dried KF.nH2O2;
• and
• (iii) delivers said individual fluid-bed particles to a separation zone where such particles are subjected to disintegration forces sufficient to break substantial portions of the layer of dried KF.nH2O2 from outer surfaces of the individual fluid-bed particles, but insufficient to substantially break said individual fluid-bed particles themselves;
• (5) separating a resulting, substantially dried KF.nH2O2 product from the individual fluid-bed particles;
• and
• (6) collecting the substantially dried KF.nH2O2 product.

A method of making a substantially dried compound having the formula KF.H2O2, said method comprising:

• (1) preparing a feed solution comprised of:
• (i) an aqueous carrier component, (ii) a KF composition that comprises from about 1.0 to about 25.0 weight percent of the feed solution, (iii) hydrogen peroxide (H2O2) that comprises from about 1.0 to about 25.0 weight percent of the feed solution, and (iv) potassium bifluoride (KHF2);
• (2) atomizing a portion of the feed solution as it enters a desiccation/evaporation chamber;
• (3) creating a fluid-bed of individual particles in the desiccation/evaporation chamber in order that the atomized portion of the feed solution entering said chamber coats the outside surfaces of said individual particles;
• (4) passing a pre-heated gas stream through the desiccation/evaporation chamber such that said pre-heated gas stream:
• (i) creates temperatures ranging from about 130° C. to about 150° in the chamber;
• (ii) entrains feed solution-coated individual particles of the fluid-bed;
• (iii) drives off the fluid carrier component of the feed solution and thereby producing individual fluid-bed particles that are coated with a layer of dried KF.H2O2;
• and
• (iv) delivers said individual fluid-bed particles to a separation zone where such particles are subjected to disintegration forces sufficient to break substantial portions of the layer of dried KF.H2O2 from outer surfaces of the individual fluid-bed particles, but insufficient to substantially break said individual fluid-bed particles themselves.
