Vapor Pressure Coefficients: p-Dichlorobenzene to Furan
Vapor pressure equation coefficients for 345 pure compounds from Perry's CEH 8th Ed. Table 2-8. Equation form: ln(P/Pa) = C1 + C2/T + C3*ln(T) + C4*T^C5, where T is in Kelvin. Each row also provides the valid temperature range (Tmin_K, Tmax_K) and corresponding pressure bounds.
