Title: **Dennis H. Michalski: Innovator in Chemical Processes**

Introduction

Dennis H. Michalski is a notable inventor located in Lakeland, Florida, who has made significant contributions to the field of chemical processes, particularly in the domain of phosphoric acid treatment. With five patents to his name, he has demonstrated a commitment to improving industrial practices related to acid stabilization and defluorination.

Latest Patents

Among his latest innovations, Michalski has developed a patent for **Lowering Post-Precipitation in Merchant Acid**. This process stabilizes merchant acid from bottom solutions against post-precipitation by heating the acid to temperatures of at least 180°F for a period ranging from 12 to 48 hours. The resultant stabilized acid product shows less than 1 wt % solids precipitation after even 14 days at 70°F.

Another significant innovation is his patent for the **Method for Defluorinating Wet Process Phosphoric Acid**. This method involves mixing phosphatic waste clay from phosphate rock beneficiation with wet process phosphoric acid and heating the mixture to remove fluorine as gaseous silicon tetrafluoride. The process not only assists in defluorination but also liberates phosphate from the waste clay, leading to the recovery of phosphate in the defluorinated product.
