Eksperimentalno određivanje gustina linalola, alfa-pinena i beta-pinena na visokom pritisku

Abstract

U cilju smanjenja zagađenja na globalnom nivou poslednjih godina aktuelna je tema zamene fosilnih goriva nekim novim biogorivima. Terpeni, koji su sastavni delovi biljaka, mogu se koristiti u ove svrhe kao dodatak standardnim gorivima. Neke od termodinamičkih svojstva pod uslovima visokog pritiska i određnih temperatura su od velike važnosti za efikasnost motora. U ovom radu su dobijene gustine linalola, alfa-pinena i beta-pinena u temperaturnom intervalu 293.15-413.15 K i na pritiscima do 60 MPa. Na osnovu ovih rezultata utvrđeno je da s porastom temperature pri konstantnom pritisku gustina navedenih terpena opada, dok sa povećanjem pritiska pri konstantnoj temperaturi gustina raste.

In order to reduce pollution at the global level in recent years, the main topic is replacing fossil fuels with some new biofuels. Terpenes, which are integral parts of plants, can be used for these purposes as an addition to standard petroelum fuels. Some of thermodynamic properties under high pressure conditions and moderate temperatures are of significant importance for engine efficiency. In this work, the densities of linalool, αpinene and β-pinene were obtained in the temperature range 293.15-413.15 K and at pressures up to 60 MPa. Based on these results, it was found that with increasing temperature at constant pressure the density of these terpenes decreases, while with increasing pressure at constant temperature the density increases.
