Abstract:1-Methoxy-2-propanol (PGMME) is widely used as an oxygenated additive for diesel fuel. Experimental speed of sound data for PGMME are very scarce. Therefore, the speed of sound in PGMME was measured by the Brillouin light scattering (BLS) method in the temperature range from (306.81 to 648.29) K and pressures up to 10 MPa, including saturated liquid/vapor, liquid, and near-critical and supercritical fluid states. The relative expanded uncertainty (k = 2) of our BLS experimental system is estimated to be less t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
