Density, Viscosity and Water Phase Stability of 1-Butanol-Gasoline Blends

Table 3

Parameters 𝐴 and 𝐵 of the linear equation 𝑦=𝐴𝑥+𝐵 in Figures 1, 3, and 4 and the correlation coefficient 𝑅² for each fit. 𝑦 is the temperature of haze point/phase separation/crystallization in °C and 𝑥 is water content in w/w%.
