Institut Català d'Investigació Química (ICIQ) posted this:Photochemical metal-free method of amination of C-H bondsA new method for the metal-free amination of C-H bonds has been developed. The method uses readily available reagents (iodine, trilfuoromethylsuylfonamide, diacetoxyiodobenzene) and light to insert a sulfonamide moiety into a C-H bond. the method has been successfully used in the preparation of various APIs (memantine, rasagiline, sertraline). The method takes place in mild conditions and allows avoiding the use of transition metal catalysis and multiple-steps procedures. Partners are sought for the joint development of commercial applications of the method.
Institut Català d'Investigació Química (ICIQ) posted this:Photoinitiators for visible-light induced living polymerizationA new class of photoinitiators of living polymerization induced by visible light has been developed and is made available for testing (under MTA) and/or licensing. The developed initiators trigger the curing of resins by irradiation with low-intensity visible light, while providing polymers with good control of chain length. In addition, through decomposition of the initator, the cured material presents a different colour than the uncured resin.

Korea Institute of Energy Research posted this:A displacement desorption process and apparatus for light olefin separation and high-purity olefin production.The present technology relates to a process and apparatus for recovering high-purity olefin from mixed gasses containing light olefins (ethylene, propylene, etc.). Olefin is a long chain polymer synthetic-fibre created when ethylene and/or propylene gases are polymerized under specific conditions. The resultant material, olefin, has a myriad of applications in manufacturing, household products, clothing and petrochemical products including plastics and packaging. Due to the non-toxicity of olefin in water, as well as the structural stability of materials manufactured using olefin fibre, the material, in its purest form, offers numerous advantages to different sectors and in several industrial processes. Generally, distillation techniques have been used to separate olefin/paraffin mixtures. However, significant challenges arise during these conventional distillation processes due to the small difference in boiling point between olefin and paraffin, and the subsequent requirement that distillation columns must have several distillation trays. This requirement later incurs high energy and equipment costs. In recent years, technology advancements have enabled the reduction in olefin separation costs by using a process of separating olefin by absorption as opposed to the traditional method of separation through distillation. This advanced olefin separation technology builds on the capabilities of recently developed absorption methods, through the addition of a sophisticated displacement desorption process of desorbing absorbed ethylene using a desorbent. Light olefins production is a multi-billion-dollar commodity industry, and the olefin separation process is the most energy-intensive operation in the production of ethylene, propylene and other high-volume olefin petrochemicals. Using this patented displacement-desorption process the high energy requirement of olefin separation can be reduced, thus saving resources and improving economic efficiency.
