Synthesis routes and methods I

Procedure details

10 kg batches of sodium perborate were treated in a series of experiments with CaCl2 in a two-stage spray process using in the first stage 1.5 kg of 30% by weight CaCl2 solution and in the second stage 1.5 kg of water, giving a perborate having a calcium content of 1.6% by weight.

Procedure details

Another aspect of the invention includes an injectible paste having a mixture of a reactive amorphous calcium phosphate powder, the amorphous calcium phosphate having a calcium to phosphorous atomic ratio in the range of about 1.55 to 1.70, and alternatively about 1.55 to 1.65, and alternatively 1.55 to 1.6, and reactive vacant sites, and a second calcium phosphate powder, and an amount of water sufficient to provide the desired consistency. The water is buffered to a physiologically acceptable pH. The paste is hardenable at body temperature.

Synthesis routes and methods III

Procedure details

The inventors have discovered that simple admixture or combination of L-carnitine, a calcium or magnesium salt, and valproic acid without a suitable solvent is not sufficient to provide an L-carnitine valproate salt of the present invention. After simple admixture or combination without a suitable solvent, L-carnitine retains its objectionable malodor and offensive taste, as well as its hygroscopicity, and valproic acid remains an oil. In contrast, use of the methods of preparing the L-carnitine valproate salt of the present invention as disclosed herein provides a composition of the present invention that is free from objectionable taste and free or nearly free from repugnant odor. Further, an L-carnitine valproate salt of the present invention has different physico-chemical properties from the starting materials. As we discovered and disclose in Example 1, for example, L-carnitine calcium valproate, an embodiment of the present invention, has a melting point of 171.2° C., different from the melting point of L-carnitine (186-190° C.) or valproic acid (an oil at room temperature and above). The 1H-NMR spectrum of L-carnitine calcium valproate (FIG. 2) differs from that of the starting materials (i.e., L-carnitine and valproic acid) and confirms the structure. L-carnitine calcium valproate is soluble in water, and aqueous solutions of this salt provide bioavailable L-carnitine, calcium, and valproate.

Synthesis routes and methods IV

Procedure details

Eggshell powder is used in the food industry, including animal and human nutritional supplements. Eggshells provide approximately 36-37 percent elemental calcium in addition to traces of phosphorous and other trace elements. Thus, for example, 500 mg of dried powdered eggshell provides approximately 180 mg elemental calcium. This compared vary favorably to other calcium salts. For example, calcium carbonate provides 40 percent elemental calcium, calcium citrate provides 21 percent elemental calcium, calcium lactate provides 13 percent elemental calcium, calcium gluconate provides 9 percent elemental calcium, dicalcium phosphate provides 23 percent elemental calcium (and 19 percent phosphorus), and bone meal provides 20 percent elemental calcium (and 17 percent phosphorus). A single large eggshell has a mass of approximately 6 g and provides approximately 2200 mg of calcium.
