Abstract: This study analyzes the contraction and concentration positions of the peculiar points in aqueous and mutual solutions of acetone and isopropanol at a temperature of 25 °C. The concentration positions of contraction maxima are located at 0.25 for acetone solutions and 0.17 for isopropanol solutions. It has been shown that the maximum contraction value of acetone-2-propanol solutions is positive and does not exceed 0.004. This indicates the absence of clusters and microinhomogeneous structures in these solutions, allowing us to consider them as close to ideal. The special points of aqueous solutions of acetone and isopropanol are close to each other, at 0.064 and 0.05, respectively. In this case, the maximum contraction value of aqueous solutions of acetone exceeds that of aqueous solutions of 2-propanol by no more than 25%. The concentration positions of the contraction maxima are located at 0.25 for acetone solutions and 0.17 for isopropanol solutions.
