Johnson Matthey Technology Review - Volume 61, Issue 3, 2017

Global methanol production in 2016 was around 85 million metric tonnes (1), enough to fill an Olympic-sized swimming pool every twelve minutes. And if all the global production capacity were in full use, it would only take eight minutes. The vast majority of the produced methanol undergoes at least one further chemical transformation, more likely two or three before being turned into a final product. Methanol is one of the first building blocks in a wide variety of synthetic materials that make up many modern products and is also used as a fuel and a fuel additive. This paper looks at the last 100 years or so of the industrial history of methanol production.

In the century since the first platinum gauze for nitric acid production was made by Johnson Matthey, the demand for nitric acid has increased considerably with its vast number of applications: from fertiliser production to mining explosives and gold extraction. Throughout the significant changes in the industry over the past 100 years, there has been continual development in Johnson Matthey’s gauze technology to meet the changing needs of customers: improving efficiency, increasing campaign length, reducing metal losses and reducing harmful nitrous oxide emissions. This article reviews the progress in gauze development over the past century and looks at recent developments.

This paper reviews the use and relation of the word ‘ptène’ to osmium. While Smithson Tennant discovered osmium in platinum ore in 1804, the French chemists Antoine-François Fourcroy and Nicolas-Louis Vauquelin simultaneously identified in a platinum residue a metal they called ‘ptène’. This name was most probably attributed to a mixture of platinoids (excluding platinum), mainly osmium and iridium. Nevertheless, Fourcroy later considered that ‘ptène’ was the name they attributed to osmium.

The remarkable benefits associated with the attraction of polyethylene glycol (PEG)-containing nanomicelles to metal nanoparticles in water allows for varying types of important catalysis to be done under very mild and green conditions.

Trends such as population growth, climate change, urbanisation, resource scarcity, conservation of energy and water, and reduction of waste and toxicity have led to the development of sustainable practices in industry, education and society. The desire to improve ways of living, the need for performance materials, and the urgency to close the gap between developed and emerging nations have propelled creative and innovative solutions based on green and sustainable chemistry to the forefront. This article provides an overview of the main impacts of green chemistry on industry, academia and society in the USA in the past ten years, as well as a summary of the drivers and barriers associated with the adoption of green chemistry practices. It also describes how researchers, policy makers, educators, investors and industries can work together to “build innovative solutions that transform and strengthen the chemical enterprise” (1) while addressing environmental and social challenges. The goal of this article is to understand why green chemistry is still primarily viewed as Joel Tickner, Director of Green Chemistry and Commerce Council (GC3), University of Massachusetts, Lowell, USA, puts it: as “an environmental activity rather than one that, as experience shows, yields economic benefit, and it has yet to be integrated into the fabric of the chemical enterprise, educational systems, or government programs” (1).

Organometallic catalysis has its origins in the 18th and 19th centuries. Then, the emphasis was on achieving remarkable chemical transformations, but today the focus is increasingly on sustainability. This article summarises the current promising approaches with special regard to those that have commercial potential, including non-aqueous and water immiscible solvents, modified enzymes, micellar catalysis, catalysis with low loading, metal-free catalysis and catalyst recycling. Environmental metrics, a key evaluation tool for any industrial chemical process, are used in micellar catalysis to demonstrate their usefulness, especially to achieve streamlined protocols, reduce losses and eliminate toxic materials.

Since the mid-1970s when the ‘Low Pressure Oxo’ process (LP Oxo^SM Process) was first commercialised, it has maintained its global position as the foremost oxo process, offering particular appeal to independent producers of commodity plasticisers facing increasing regulatory pressure. The story of this important industrial process is told from its early beginnings when laboratory discoveries by independent groups of researchers in USA and UK revealed the remarkable ability of organophosphine containing rhodium compounds to catalyse the hydroformylation reaction, and describes how its development, exploitation and continuing industrial relevance came about by collaboration between three companies: The Power-Gas Corporation, which later became Davy Process Technology before becoming part of Johnson Matthey; Union Carbide Corporation, which became a wholly owned subsidiary of The Dow Chemical Company; and Johnson Matthey.
