Organization from United States posted this Technology CallSeeking IDEAS for a new process to separate close boiling nitrile isomers more cost effectively.There is a byproduct stream from an adiponitrile process that consists of an isomeric mixture of close-boiling, unsaturated, short-chained nitriles (branched and linear), such as 2-pentenenitrile. Traditionally, distillation has been used to separate these isomers. This is an expensive process that leads to higher material cost which subsequently limits the number applications in which these molecules can be used. An alternative technology is sought to the current distillation process that can separate these close boiling isomers more cost effectively. We are seeking existing or early, unproven but plausible ideas for further consideration. Proposers of ideas found to be of interest may be contacted for further paid consultation to discuss.
Organization from European Union posted this Technology CallSeeking eco-friendly UV-light stabilizersPolymers are continuously subjected to the action of different stress factors, such as oxygen, heat, UV light, mechanical stress, humidity, etc., during their processing and service life, undergoing overall oxidative degradation, that causes performance and property deterioration. To improve the resistance at high temperatures and long-term weatherability of the polymers during their manufacturing, synthetic antioxidants and UV-light stabilizers are added. Many of these established UV-light stabilizers are seemingly becoming a threat to human health, the environment and natural resources as they are evidently presence in our aquatic ecosystems and persistence in the environment. The company is seeking eco-friendly or/and alternative compounds suitable to be used as UV-light stabilizers for the plastic industry.
Strategic Allies Ltd. posted this Technology CallSeeking Scientific support with expertise in organic and inorganic chemistryWe are working with a consumer product company that is seeking scientific support services to assist in understanding of the chemistry of the materials it considers using in its products/consumables and how they may react under the influence of heat or other interactions. The client therefore requires proven competent scientific support with expertise in organic and inorganic chemistry to supply desk based activity on an ad hoc basis. These scientific support services include being able to review chemistry covering material form and potential interactions between materials or other elements such as liquids, function and reactivity, from available literature and also from first principles. Examples could include: • Organic chemistry: The breakdown of flavour ingredients from thermal interactions, UV exposure or when mixed with solvents or in a matrix of compounds. • Organic chemistry: The stability of flavour ingredients • Inorganic chemistry: The interaction of acids and metals, in liquid and aerosol, especially in terms of galvanic cell reactions • Materials science: The absorption properties of materials and specific interactions with target compounds • Investigating target compounds and potential routes to formation and reactions
