Organic Catalyst Boasts Big Benefits

Article | June 6, 2022

An enzyme-mimicking catalyst opens a new route to important organic molecules such as glycolic acid and amino acids from pyruvate, report researchers in Japan. Moreover, the new catalyst is cheaper, more stable, safer and more environmentally friendly than conventional metal catalysts used in industry, they note, adding that it also displays the high enantioselectivity required by the pharmaceutical industry. “On top of these advantages, our newly developed organic catalyst system also promotes reactions using pyruvate that aren’t easily achievable using metal catalysts,” says Santanu Mondal, a PhD candidate in the chemistry and chemical bioengineering unit at Okinawa Institute of Science and Technology (OIST) Graduate University, Okinawa, Japan, and lead author of a study recently published in Organic Letters. “Organic catalysts, in particular, are set to revolutionize the industry and make chemistry more sustainable,” he stresses. The researchers use an acid and an amine mixture to force the pyruvate to act as an electron donor rather than its usual role as an electron receiver (Figure 1). Effectively mimicking how enzymes work, the amine binds to the pyruvate to make an intermediate molecule. The organic acid then covers up part of the intermediate molecule while leaving another part that can donate electrons free to react to form a new product. Currently, the organic catalyst system only works when reacting pyruvate with a specific class of organic molecule called cyclic imines. So, the researchers now are looking to develop a more-universal catalyst, i.e., one that can speed up reactions between pyruvate and a broad range of organic molecules. The challenge here is to try to make the electron-donating intermediate stage of pyruvate react with other functional groups such as aldehydes and ketones. However, different catalysts create different intermediates, all with different properties. For example, the enamine intermediate created by the researchers’ new reaction only reacts with cyclic imines. Their hypothesis, currently being investigated, is that creation of other intermediates such as an enolate, if possible, would achieve a broader pyruvate reactivity. In terms of cost, the researchers note that a palladium catalyst used in similar reactions is 25 times more expensive than their organic acid — which also is made from eco-friendly quinine. In addition, they believe scale-up of the process for industrial use definitely is possible. However, the researchers caution that the current amine-to-acid-catalyst loading ratio of 1:2 probably would need to be optimized for better results at a larger scale.

Transporting biological and chemical materials - what you need to know

Article | June 29, 2021

The landscape of biological and chemical logistics has changed rapidly - as have the regulatory frameworks around it. What has not necessarily kept pace is the end-user understanding of the nature of these logistical processes, their opportunities and their constraints. Twenty years ago, the transmission of biological and chemical materials was limited to a small range of organisations: usually national and international research companies, hospitals, major university departments, police and military departments with forensic responsibilities.

Setting record straight on testing harm in chemicals

Article | June 13, 2021

The modern world is built on chemicals, be it the medicines we use, or cleaning fluids, crop protection products, or the raw materials for everything from laptops and mobile phones to clothes and furniture. Across all, we have created an entire modern society with chemicals, and, as a result, constantly stretched the size of the world population we can feed, clothe and shelter. Yet, balancing all the gains from the modern chemistry around us against any negative environmental and human impact has been a rising concern, making for ever greater focus on testing and on risk assessment.

Why chemical characterization is the best way to assess patient risk

Article | February 11, 2020

Everyone is very familiar with the phrase when buying a house: All that really matters are three things - location, location, and location. This same principle applies to extractables and leachables chemistry analysis – the three things that truly matter are identification, identification, and identification. The greatest growth in the past ten years in demonstrating the safety of medical devices and container closure systems for drugs has been using analytical chemistry to determine what chemicals can leach from the device and what the patient is exposed to during its intended use.

Oil giants' chemical lifeline threatened by plastic-trash crisis

Engineering News | June 06, 2019

As the world strives to wean itself off fossil fuels, oil companies have been turning to plastic as the key to their future. Now even that’s looking overly optimistic. The global crackdown on plastic trash threatens to take a big chunk out of demand growth just as oil companies like Saudi Aramco sink billions into plastic and chemicals assets. Royal Dutch Shell, BP, Total and Exxon Mobil are all ramping up investments in the sector. Renewed emphasis on recycling and the spread of local bans on some kinds of plastic products could cut petrochemical demand growth to one-third of its historical pace, to about 1.5% a year, said Paul Bjacek, a principal director at consulting firm Accenture.

Storage Tank Explosion Rocks Arkansas Chemical Facility

Powder & Bulk Solids | June 03, 2019

A 6000-gal storage tank exploded at the Org Chem Group chemical processing plant in Hot Springs, AR in the early hours of Friday morning, the Hot Springs Sentinel-Record reported. The blast at the Blacksnake Road site was reported at about 2 a.m., drawing a response from area firefighters and a HAZMAT team, Bo Robertson, the director of Garland County Department of Emergency Management, told the newspaper. A lawyer for the chemical company said in the Sentinel-Record’s coverage that the storage tank was holding about 3000 gal of a liquid composed of 80% water and 20% sodium hydroxide when the explosion occurred. No chemicals were released into the air or the area surrounding the plant and no injuries were logged. The newspaper said operations at the Org Chem Group facility were uninterrupted.
