STUDY ON THE INTERACTION OF AMIDOESTERS WITH VARIOUS PETROLEUM ACID COMPOSITIONS AS ANTISTATIC ADDITIVES IN DIESEL DISTILLATE

Compositions were formulated using monoethanolamine, diethylenetriamine, and natural petroleum acids synthesized in a 1:1 molar ratio, along with amidoesters derived from various fatty acids (sunflower, soybean, cottonseed, and corn). These compositions were prepared at temperature fractions of 200-280 degrees C and 280-340 degrees C. The structural characteristics of the synthesized amidoesters were confirmed through infrared (FTIR) spectroscopy. The prepared compositions were introduced into diesel fuel at varying concentrations (0.05, 0.1 and 0.15%), and their influence on the electrical conductivity of the fuel was evaluated. Initially, the electrical conductivity of diesel fuel without additives was measured, revealing a conductivity of 85 pS/m after one day. Over the course of 10, 20, and 30 days, the conductivity remained consistent at 77 pS/m. The findings of this study indicate that after 40 days, the electrical conductivity of diesel fuel increased to 1089, 1530, and 2345 pS/m when 0.05, 0.1 and 0.15% of the 280-340 degrees C fraction of petroleum acid was incorporated into the composition of amidoesters synthesized from cottonseed fatty acid and diethylenetriamine, serving as antistatic additives in diesel fuel. Furthermore, when the 200-280 degrees C fraction of amidoester synthesized from cottonseed fatty acid and diethylenetriamine, along with a 1:1 molar ratio of natural petroleum acid, was introduced into diesel fuel at the same concentrations, the electrical conductivity exhibited an even greater increase, reaching 1245, 1560, and 2072 pS/m, respectively. Additionally, it was established that the combination of amidoesters synthesized with diethylenetriamine and various fatty acids, along with natural petroleum acid fractions, effectively enhanced the electrical conductivity of diesel distillate, confirming their role as antistatic additives
