Abstract | Medium-temperature coal tars, Just like the high-temperature ones, are primary source for chemical industry, and call more and more attention by far. The adequate characterization of their features is critical for their efficient utilization, but little reports were issued, if any. This work performed anslysis of a medium-temperature coal tar by a Gas Chromatograph/Mass Spectrometer. Totally 139 compounds were detected in the sample, incliuding oxygen-containing compounds, aromatic hydrocarbons, aliphatic hydrocarbons and polycyclic hydrocarbons. Among which the phenoids and normal alkanes are in quite high abundances, while the aromatic and polycyclic hydrocarbons involve quite a variety of species but in very low abundances. This result shows a rosy possibility of medium-temperature coal tar for phenoid production. This work also provides helpful information for coal chemistry research. The result suggests a lot of linkages of -O- inside the coal structure and the mainly aromatic units being of 2 to 3 rings, while the polycyclic hydrocarbons can survive the medium- or low- temperature coking, thus providing an assistant tool for studies on geochemistry and coal geology. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
