In this article, we determined by IR spectroscopy the composition of the following adipic esters: isotridecyl adipate and 2-(p-nonyl-phenoxy) ethyl, isotridecyl adipate and 2-(o-sec-butyl-phenoxy) ethyl and isotridecyl adipate and 2-phenoxy ethyl. The absorption spectrum of isotridecyl adipate and 2-(p-nonyl-phenoxy) ethyl is between the wave numbers 2958 cm^-1 and 629 cm^-1. The absorption spectrum of isotridecyl adipate and 2-(o-sec-butyl-phenoxy) ethyl is between the wave numbers 2959 cm^-1 and 751 cm^-1. The absorption spectrum of isotridecyl adipate and 2-phenoxy ethyl is between the wave numbers 2958 cm-1 and 752 cm^-1. IR spectra for adipic esters were obtained on a Jasco 430 FT-IR spectrophotometer.
