Overview

Randomized trial examines viscosity prediction in ethyl octanoate and n-alcohol mixtures, indicating improved modeling accuracy.

Key Points

  • The aim is to enhance the predictive accuracy of viscosity for binary mixtures of ethyl octanoate and n-alcohols using an improved MTSM model.
  • Experimental viscosity measurements were conducted using a self-designed capillary viscometer.
  • Binary mixtures of ethyl octanoate and n-alcohols (C3/C5–C7) were tested over a temperature range of 293–333 K.
  • Four models, including the modified two-suffix Margules model, were compared for accuracy in predicting viscosity.
  • The correlation coefficient between the correction term and the ln of viscosity is 0.95.
  • The average deviation of the improved model is reduced by 3.44 × 10–4.
  • The average absolute relative deviation decreased by 0.30% compared to the original MTSM model.
