First Steps: Synthetic Ammonia in the United States

Abstract

The synthetic ammonia industry, originally based on Fritz Haber's 1909 invention of a catalytic high-pressure method as scaled up by Carl Bosch at BASF, grew globally in the years following World War I, based on the processes of Brunner, Mond & Co. (Britain), Luigi Casale (Italy), Georges Claude (France), and Giacomo Fauser (Italy). The ammonia was mainly converted into ammonium sulphate fertilizer. There was less impetus in the United States for taking up these developments, because America relied on ammonium sulphate from its by-product coke ovens, sodium nitrate (Chilean nitrate) from South America, ammonia from coal gas works, and calcium cyanamide as manufactured by the American Cyanamid Company. Even when a synthetic ammonia industry started up in the United States, it was on a smaller scale than in Europe. However there emerged just before the Wall Street Crash two major producers of synthetic ammonia, Allied Chemical and Du Pont. This article presents a historical reconstruction of the early synthetic ammonia industry in the United States focusing on the 1920s, paying particular attention to Du Pont's success, which relied on the ammonia process of Casale. Standard accounts suggest that Du Pont acquired Casale technology as the result of a straightforward business acquisition. However, the situation, as shown here, was far more complex. Du Pont had to engage in aggresive litigation in order to acquire rights to the Casale process in 1927.

Highlights

The 1920s were the take off years for science-based chemical industry in the United States
Dangers, including explosions and casualties, Du Pont began to take an interest in the Casale process, no doubt in part because, having invested in hypercompressors, it wished to continue working with pressures way beyond those used in other synthetic ammonia processes
Apart from these considerations, Casale’s process was still the only independent, well-tried process suited to large scale production available for licensing in the United States in 1926

Summary

INTRODUCTION

The 1920s were the take off years for science-based chemical industry in the United States. Dangers, including explosions and casualties, Du Pont began to take an interest in the Casale process, no doubt in part because, having invested in hypercompressors, it wished to continue working with pressures way beyond those used in other synthetic ammonia processes (all of which Du Pont intended to outperform) Apart from these considerations, Casale’s process was still the only independent, well-tried process suited to large scale production available for licensing in the United States in 1926 (the German Mont Cenis and the Nitrogen Engineering Corporation processes were new, and the Italian Fauser process was in the hands of Montecatini, which had only just started to consider licensing arrangements). In 1930, Du Pont acquired Roessler & Hasslacher Co.; in 1932 it became the R&H Division of Du Pont (and later the Electrochemicals Division)
