Title: Leland L Frederick: Innovator in Fertilizer Solutions

Introduction

Leland L Frederick is a notable inventor based in Florence, AL (US). He has made significant contributions to the field of agricultural chemistry, particularly in the production of fertilizers. With a total of 3 patents to his name, Frederick's work has had a lasting impact on the industry.

Latest Patents

Frederick's latest patents focus on the production of ammonium potassium polyphosphates. In his first embodiment, he describes a process where urea phosphate, prepared from wet-process phosphoric acid, is heated with monopotassium orthophosphate in a mole ratio of 0.25 to 4.0 at temperatures ranging from 130°C to 200°C. This process results in an ammonium potassium polyphosphate with an average chain length between 1.2 and 2.5. The final product is then dissolved in aqueous ammonia, yielding concentrated fertilizer solutions that contain the three major nutrients and over 50 percent total plant food. In the second embodiment, phosphoric acid containing 54 to 76 percent P₂O₅ is heated with urea and monopotassium orthophosphate under similar conditions to produce another variant of ammonium potassium polyphosphate.
