| Abstract | The rapid increase in the production rates of bioalcohols (in particular bioethanol) gives grounds for regarding them as a promising renewable chemical raw material for obtaining a number of useful organic synthesis products. In order to develop new green technologies for processing ethanol into value-added products, a systematic study of selective conversion of ethanol under conditions of oxidation by molecular oxygen in the flow gas-phase mode over such catalysts as V$_{2}$O$_{5}$-TiO$_{2}$, mixed oxides V-Mo-Te, V-Mo-Nb and V-Mo-Te-Nb, and gold supported on oxide supports is performed. The catalytic activity is determined under conditions of temperature-programmed reaction under atmospheric pressure using a gas mixture (composition, mol %: EtOH, 2; O$_{2}$, 18; He, 80) at a hourly space velocity of the mixture of 3600 h$^{−1}$ over 0.25–0.5 mm catalyst fraction. The possibility of the efficient conversion of ethanol to products of partial oxidation and accompanying conversions (acetaldehyde, 90–99% yield; acetic acid, 92-98% yield; productive capacity >3 g g-cat$^{−1}$ h$^{−1}$) and acetic acid-ethyl acetate mixtures (1: 1 ratio, total yield >90%) in a number of cases is demonstrated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
