The experimental values of densities [rho], excess volumes [V.sup.E], viscosities [eta], speeds of sound u, and isentropic compressibility [k.sub.s] of the binary mixtures of methyl benzoate
with tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether at temperatures 303.15, 308.15, and 313.15 K are listed in Table 2.

Chemist Aijun Zhang, with the Agricultural Research Service Invasive Insect Biocontrol and Behavior Laboratory in Beltsville, Maryland, has found a new use for methyl benzoate
, namely as an environmentally friendly control for agricultural pests like the spotted wing drosophila fly (SWD), an invasive species from Asia.
