Problems solved by technology

However, current techniques either require large amounts of base to neutralize the acid produced and / or they use multiple process steps to perform reaction and purification of the final product.
In addition, current methods are limited to batch or semi-batch processing, thus reaction equilibria can limit the extent of reaction.

example 1

[0103]A solution of titanium oxychloride (TiOCl2, 400 grams (g)), glycerol (400 g) and water (distilled, 400 g) was fed continuously by a metering pump into the reaction distillation zone at a rate of 1.75 liters / minute (L / min). Heating (at about 80° C.) under reduced pressure at about 98.2 kPa (about 29″ Hg) gave rise to a vapor phase containing essentially water and about 20 to about 30% hydrochloric acid that was continually withdrawn and collected by vapor condensation. The viscous liquid phase product was continuously withdrawn from the reactor and treated to remove residual acid and excess glycerol. The resulting free flowing white powder product weighed about 340 g. Analysis of the product was consistent with titanyl glycerolates as confirmed by elemental analysis, 1H- and 13C-NMR.

example 2

[0104]A solution of hydrated zinc acetate (Zn(CH3CO2)2*4H2O, 400 g), glycerol (400 g), and water (distilled, 400 g) is fed continuously by a metering pump into the reaction distillation zone at a rate of 1.75 L / min. Heating under reduced pressure evolves initially water then acetic acid vapors that are continually withdrawn and collected by vapor condensation. The viscous liquid phase product is continuously withdrawn from the reactor and treated to remove residual acid and excess glycerol. The resulting free flowing white powder product when analyzed will be consistent with zinc(II) glycerolate.

example 3

[0105]A solution of hydrated manganese acetate (Mn(CH3CO2)2*2H2O, 400 g), glycerol (400 g), and water (distilled, 400 g) is fed continuously by a metering pump into the reaction distillation zone at a rate of 1.75 L / min. Heating under reduced pressure evolves initially water then acetic acid vapors that are continually withdrawn and collected by vapor condensation. The viscous liquid phase product is continuously withdrawn from the reactor and treated to remove residual acid and excess glycerol. The resulting pink powder product when analyzed will be consistent with manganese(II) glycerolate.
