Title: **Michael J. Spangler: Innovator in Polyoxymethylene Dimethyl Ethers**

Introduction

Michael J. Spangler, based in Sandwich, Illinois, USA, is a prolific inventor with a significant portfolio of 26 patents. His work focuses primarily on the development of innovative processes in the chemical industry, particularly in the area of polyoxymethylene dimethyl ethers (PODME). His inventions have contributed to advance methodologies that are essential for the conversion of methanol and dimethyl ether into useful chemical products.

Latest Patents

Two of Spangler's latest patents highlight his groundbreaking work in catalytic processes. The first patent details the "Preparation of polyoxymethylene dimethyl ethers by acid-activated catalytic conversion of methanol with formaldehyde formed by dehydrogenation of methanol." This process involves a complex feedstream containing methanol, a soluble condensation-promoting component, and a source of formaldehyde. The innovative catalytic distillation column separates methylal and higher polyoxymethylene dimethyl ethers, producing acid-free products that are appropriate for blending into fuel.

The second patent outlines the "Preparation of polyoxymethylene dimethyl ethers by catalytic conversion of formaldehyde formed by oxidation of dimethyl ether." This method also utilizes a catalytic distillation column to convert methanol and formaldehyde into valuable chemical products while allowing the recycling of unreacted dimethyl ether. As with his previous work, the resulting acid-free product can be directly blended or fractionated for diesel fuel applications.
