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.

SEE THE END section of this blog post for a dystopian version of our environmental future. In a follow-up post – which I will publish on Thursday, 1 July – I will offer some suggestions about how we can avoid an outcome that nobody of course wants.Both posts are meant to be provocative, challenging and controversial because only through debate, and sometimes outright argument, will we get to the answers.
If you disagree after either or both posts have been published, great, that would be good. In fact, I would love to hear from you whatever your views at john.richardson@icis.com. The petrochemicals industry can do this; we can fix this if we create the right forums for ideas and then solutions.
Let me provide the background first. Let me start by examining developments in the refinery industry and the implications for petrochemicals as important background. Then I will look at a sample of ICIS petrochemicals demand growth forecasts for 2020-2040. I will conclude by providing the bleakest of bleak outcomes for the world in 2025

The chemical business is intricate, with numerous sub-sectors dealing with various challenges. Thus, there are some differences in the sector's main areas of digitalization. For instance, while specialty chemicals with smaller batches but larger profit margins are concerned with improving quality, large factories are concentrated on accelerating throughput speed.
To be able to react to quick and repeated changes in demand, supply, and working circumstances, however, every plant must optimize output, reduce waste, improve safety and sustainability, and become more nimble. Therefore, the Industrial Internet of Things (IIoT), artificial intelligence (AI), and cloud computing are expected to be the three most popular applications for digital transformation during the coming two years.
Key Trends
Production Optimization
The first and most valuable use cases of digitalization in chemical plants center on production optimization through improved equipment performance, process automation, remote and predictive monitoring, and simplified maintenance.
Chemical factories, which often provide basic chemicals for use as end products in other sectors, have a special responsibility to maintain consistently high product quality. However, doing so can be challenging given the significant variations in raw material supply and quality. In addition, as process engineers can change the mix on the fly in reaction to fluctuations in quality, feedstock, or ambient temperatures, better data and analytics enable finer and more frequent adjustments.
Lowering Waste
The main advantage of digitally transformed plants so far has been cost reduction. The price volatility of raw materials is a problem for the chemical production sector because customers naturally want constant low prices. Minimizing waste is critical since facilities must contend with rising energy costs.
Analytics tools that monitor fluctuating raw material prices aid factories in negotiating the best deals with suppliers and preparing in advance for price spikes. The risk of oversupply is reduced since plants can prepare the proper quantities of various products thanks to more precise demand predictions.
Sustainability, Compliance, and Safety
The chemical industry is heavily regulated as a result of the quantity of hazardous chemicals and the number of end-use industries that rely on it. Businesses are adopting digital transformation to boost safety awareness, reduce emissions and dangerous flare incidents, and guarantee a transparent and accurate audit trail.
Plants that quickly adopt digital solutions for remote monitoring, supply chain visibility, waste reduction, production optimization, raising their safety profile, and opening up new opportunities will profit from higher profits and increased revenue, whereas those that hesitate for too long risk failing in the long run.

Used to separate and analyze compounds into their various components— chromatography plays a crucial part not just in the food industry but in the realms of drug testing, forensics, and even quality control in our favourite alcoholic drinks as well.
Advanced Chromatography is an analytical technique introduced to the world by chromatography instrument companies to separate and analyze individual chemicals from complex compounds. Recent developments in the biotechnology and pharma industries have created a significant surge in the chromatography market.
Read on to find out five fascinating facts about the day-to-day applications of chromatography in various industries and why businesses are looking to invest more in OEM chromatography manufacturing.
Why are Industry-Decision Makers Adapting to Chromatography?
Liquid Chromatography; A Popular Choice in Drug Testing
Today, a lot of drug tests use liquid chromatography-mass spectrometry because it is easy to use, widely available, and gives quick results. LC and LC-MS can be done in almost any testing facility, which is different from other methods. It can be run by people with little training, so a testing facility can hire mostly technicians instead of highly trained scientists, who are harder to find. LC-MS is also very accurate, which means that there are fewer false positives.
With liquid chromatography, you can get results in about 10 to 30 minutes, which is very fast. This technology is used by many drug testing labs across the country. It is widely used and trusted for testing drug samples and many other things.
