Concerns of refinery industry due to obligatory use of fatty acids methyl esters for production of diesel fuel have been presented. The paper puts an emphasis on importance of ester quality as fuel component. So far problem of the esters influence on stability and other operational properties of diesel fuel is being unsolved. To obtain more experience and to diminish a risk connected with use of these fuels, making further tests have been suggested. The paper also describes the use of IR spectrophotometry and chromatography LC/GC to determine the content of fatty acids methyl esters and glycerides in diesel fuels. The obtained results were compared with results obtained by other authors by use of different methods.
