Following Leuchter, Prof. James Roth, director of a chemical laboratory in Massachusetts, also took the witness stand to describe the results of his analysis of the 32 masonry samples, the origins of which had been unknown to him All samples taken from the gas chambers supposedly used for mass human extermination exhibited either no or only negligible traces of cyanide, while the sample from the delousing chambers taken for use as control purposes exhibited enormously high cyanide concentrations.27...

A new corny joke was recently added to this debate by Prof. James Roth from the Alpha Analytic Laboratories, Ashland, Massachusetts. I discuss this event here because Prof. Roth s allegations were widely publicized by the international media in connection with the libel case of British historian David Irving against Deborah E. Lipstadt.157...

James Roth (Air Products), a member of CCR s Governing Board and a leading scientist in catalysis research, noted in a recent C EN article (September 3,1990, p. 30) that our nation is lagging behind Japan in catalysis development. CCR s participation in the conference on catalysis to be held in Lexington in 1991 is in response to this concern. 

The production of another important chemical and polymer intermediate, acetic acid, was revolutionized by the Wacker process that was introduced in 1960. It was a simple, high yield process for converting ethylene to acetaldehyde, which replaced the older process based on ethanol and acetylene. In the Wacker reaction, the palladium catalyst is reduced and then reoxidized. Ethylene reacts with water and palladium chloride to produce acetaldehyde and palladium metal. The palladium metal is reoxidized by reaction with cupric chloride, which is regenerated by reaction with o gen and hydrochloric acid. In 1968, BASF commercialized an acetic acid process based on the reaction of carbon monoxide and methanol, using carbonyl cobalt promoted with an iodide ion (74). Two years later, however, Monsanto scored a major success with its rhodium salt catalyst with methyl iodide promoter. Developed by James F. Roth, this new catalyst allowed operation at much milder conditions (180°C, 30-40 atm) and demonstrated high selectivity for acetic acid (75).
