University of Vigo posted this:A novel mild and efficient method to prepare ε-Caprolactam precursor of Nylon 6ε-Caprolactam, the main precursor of the synthetic fibber Nylon 6, is prepared from cyclohexanone oxime by treatment with a new salt as promoter. This procedure requires mild reaction conditions and affords excellent levels of conversion and selectivity to obtain pure ε-caprolactam. No reaction by-products are formed. The new promoter salt is cheap, no corrosive, and easy to prepare. All these characteristics makes the procedure suitable for undustrial purposes.
Consejo Superior de Investigaciones Científicas posted this:Enzymatic production of 2,5-furandicarboxylic acid from 5-methoxymethylfurfuraa a l l CSIC, University of Zaragoza and Technische Universität Dresden have developed an enzymatic composition and its use as an enzymatic cascade for the production of 2,5-furandicarboxylic acid (FDCA) from 5-methoxymethylfurfural (MMF). This cascade is self-sustained with the only consumption of atmospheric oxygen and the MMF itself. The method can be applied to the conversion of MMF into FDCA step in the bioplastic producing industry, switching from the current inorganic catalysts employed to the use of enzymes for the FDCA production. Industrial partners are being sought to develop and commercialize the enzymatic composition through a patent licence agreement. An offer for Patent Licensing

Institut Català d'Investigació Química (ICIQ) posted this:Adipic acid(s) prepared by catalytic carboxylation of 1,3-butadieneAdipic acid is mainly used industrially in the production of nylon 6,6. The offered technology consists in a nickel catalyzed process of carboxylation of butadiene. The developed process allows preparing adipic acid from carbon dioxide and 1,3-butadiene through a cost effective and competitive process. Industrial partners are sought for process optimization and/or industrialization.
Universidad de Alicante posted this:System for fixing armours during concretingThe research group “Materials and Construction Systems for Buildings”, from the Building and Urbanism Department of the University of Alicante, has developed a new and simple system that allows to fix any type of armours in concrete construction elements during the concreting process. This system avoids the movement of the armours in an efficient, technical and reusable way, and, therefore, also avoids future expensive treatments in case of unwanted movements. This new system is characterized by its low cost, light weight, ease of use and versatility for any constructive element. The research group is looking for companies interested in commercial exploitation.

Universidad de Alcalá-OTRI posted this:New organo-metallic catalysts for the manufacture of polymersA research group from the Inorganic Chemistry Department of Alcalá University has developed a technology that presents a range of catalysts based on coordination complexes and organometallic, active in functionalization processes (expoditation, hydrosilylation) and polymerization of different organic substrates (olefins and cyclic esters). They are metal complexes belonging to the first transition groups (groups 4-6) and elements from the main groups (groups 1,2 and 13). Its application is aimed at the synthesis of materials with new properties (silicon polymers, biodegradable plastics, polyesters) and the production of small molecules with high added value, used as starting products in many industrial processes (epoxides, silanes). The group is looking for manufacturing agreements and joint venture agreements with companies from the agrofood industry, construction and petrochemicals.

Universidad de Alicante posted this:New procedure for the elimination of printed ink from plastic filmThe most innovative aspects of this technology are: • The process for the removal of the ink is completely innovative and ecological, because it does not use organic solvents. • The technology has been successfully tested on different plastics, such as Polythene, Polypropylene, Polyester and Polyamide. It is viable for both water and solvent based inks.
Universidad de Alicante posted this:New catalyst that eliminates efficiently chlorinated volatile organic compounds in gaseous streamsThe new mixed oxide catalyst of cerium-praseodymium (CexPr1-XO2) allow the efficient combustion of chlorinated volatile organic compounds (especially 1,2-dichloroethane). These new catalytic systems are able to work in gas streams at temperatures between 250-500 º C in an dynamic and continuous way without suffering a significant deactivation process. In recent years, environmental legislation has restricted the air emissions permissible levels, and particularly the emission of volatile organic compounds (VOCs) harmful for both the environment and human health There is a wide variety of VOCs, of different chemical nature (aliphatic, aromatic, oxygenated and halogenated compounds) and consequence of different emission sources (waste gases from chemical plants, soil and water decontamination, solvents evaporation , etc..), but 1,2-dichloroethane (DCE, C2H4Cl2) is the most lasting, dangerous and commonly used in industry (used, for example, massively in the process of polyvinyl chloride production and consequently chemical plants produce significant amounts of waste that require efficient treatment). Until a few years ago, VOCs were usually eliminated by thermal incineration. However, new legislation on VOC emissions has originated significant improvements on treatment technologies. This is the case of the catalytic oxidation that in recent years has shown its ability to destroy VOCs at temperatures below those used in thermal incineration and has also produced a significant reduction of secondary pollutants (nitrogen oxides). Currently, catalytic oxidation processes require heating large gas flows that contain a small amount of VOCs and put the gas in contact with solid catalysts that can either be • Those containing noble metals as active phase: they have a excellent oxidation efficiency, although their cost is very high and gradually lose their activity with the presence of chlorine in the reaction mixture. • Those containing transition metals: they have a lower cost and are more stable and durable, although less active than those containing noble metals.
