Experimental Determination of NH3 Solubility in Toluene at Pressures up to 340 kPa at 398 K

Abstract

The solubility of ammonia in toluene has been measured at 398 K and at pressures up to 340 kPa using a static, synthetic and isochoric technique. The goal of the present study is to determine the equilibrium solubility of ammonia in toluene at a pressure and temperature regime that is relevant to the reaction conditions of amination of 1,3,5-trichloro-2,4,6-trinitrobenzene leading to the formation of 1,3,5-triamino-2,4,6-trinitro benzene. The ammonia solubility data in toluene were hitherto unavailable under these experimental conditions. The solubility data have also been compared with the result obtained from a direct sampling method. The results are in agreement with Krichevsky-Kasarnovsky equation. The Henry's law constant at the reaction temperature has been determined.
