With a total of seven patents to his name, Grote's work has had a considerable impact on various chemical processes.
Latest Patents
One of Dace Grote's latest patents involves the formation of hydroxy aryl carboxylic acids. This process entails reacting a hydroxy aryl compound, such as phenol, with a ketone, like acetone and carbon monoxide, in the presence of a strong acid. The preferred embodiment of this invention is the one-step formation of 2-methyl-2-(p-hydroxyphenyl) propionic acid from phenol, acetone, and carbon monoxide using hydrofluoric acid. Additionally, when this reaction is conducted in the presence of methanol, the corresponding methyl ester is produced. Another significant patent addresses the separation of hydrofluoric acid in a carbonylation process. In this method, hydrofluoric acid is isolated from the carboxylic acid through an ion-permeable membrane, allowing for the recycling of the acid to catalyze the carbonylation reaction again.
