These events affected our lives in many ways expos- ing rifts and inequities in society, like never before. They serve as a pow- erful reminder that ensuring social justice is an important component of achieving sustainability, as enunciated by the United Nations Sustainable Development Goals. The Center for Environmentally Beneficial Catalysis (CEBC) welcomes input from all stakeholders and remains fully committed to addressing the grand challenges of sustainability, including embracing diversity, equity and in- clusion as core values. Amid the tumult, a landmark event happened recently with lasting impli- cations on protecting our planet. The Sustainable Chemistry Research and Development Act was passed by the United States Congress. This bipartisan bill means that sustainable innovation becomes the law of the land. It is fitting that this law was passed during the year that marked the 50th Earth Day celebration. Previous Earth Day anniversaries celebrated the establish- ment of the Environmental Protection Agency as well as the passage of several landmark environmental legislations, including the Clean Air, Clean Water and Endangered Species Acts. And in 2016, the United Nations chose Earth Day to sign the historic Paris Agreement on climate change. Passage of this law comes at a time when the global chemical industry is poised to invest in manufacturing to meet the rising demand for ev- eryday products. The expansion thus provides an opportunity for the in- dustry to transition to more sustainable technologies and raw materials. To aid this global effort, CEBC researchers are investigating renewable and recycled sources of carbon such as plant-based biomass, CO2 and end-of–use plastics as feedstock to make chemicals. We are using state- of-the-art tools to develop catalysts and technologies that minimize harm to the environment and human health. Some of these achievements are highlighted in this report. The resilience and productivity shown by the CEBC researchers and staff during the pandemic has been remarkable and inspirtional. With the help of our campus administrative leaders, we came together to ensure that we effectively sustain our mission. Our center will continue to thrive not only because of the many opportunities it provides to stakeholders but also on how they nurture its growth by impactful outputs. We owe much gratitude to our industry partners and science advisory board members for their steadfast support and guidance of our mission. We look forward to emerging even stronger with a brighter future. ACS Sustainable Chem.

  • Working with Hazardous Chemicals
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk.

Received: 11 December 2019; Accepted: 11 February 2020; Published: 14 February 2020 Abstract: Aiming to synthesize high-value renewable monomers for the preparation of renewable specialty polyamides, we designed a new protocol. Amino-esters, produced via the hydrogenation of unsaturated nitrile-esters, are alternative monomers for the production of these polymers. A high monomer yield can be obtained using a Raney®-nickel catalyst despite the drawback of fast deactivation. The hydrogenation of 10-cyano-9-decenoate (UNE11) was tentatively reactivated by three different regeneration procedures: solvent wash, regeneration under hydrogen, and regeneration under sonication. Among these procedures, the in-pot catalyst regeneration (H2 30 bar, 150 ◦C) demonstrated complete activity recovery and full recycling. Keywords: bio-based monomers; amino-esters; hydrogenation; Raney®-nickel regeneration 1. Introduction The impressive growth in demand for biodegradable or renewable polymers from several industrial fields is a dramatic driving force for new investigations.
