Measurements of Saturated Vapor Pressure above the Liquid Phase for Isomeric Dichlorobenzenes and 1,2,4-Trichlorobenzene

Abstract

Saturated vapor pressures have been measured for liquid 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,4dichlorobenzene, and 1,2,4-trichlorobenzene by precision comparative ebulliometry over an approximate pressure range from 6 to 105 kPa. The relative error in pressure is estimated to be less than or equal to (0.05% of the measured value and the absolute error in temperature is estimated at less than or equal to (0.01 K on ITS-90. The results have been represented by the Antoine and Wagner-type equations within experimental uncertainties and compared with the data so far available in the literature. On the basis of the present and previous measurements, vapor pressure equations for the chlorobenzenes covering the entire range of liquid existence have been constructed and discussed.

Sorption of Chlorobenzene Vapors on Styrene−Divinylbenzene Polymer

“…To predict the specific retention volume V g , 20 /L·g -1 of a wide range of organic compounds on styrene−divinylbenzene and ethylvinylbenzene−divinylbenzene sorbents at 20 °C, Pankow et al proposed the following general equations: On 3M(a) (350 m 2 ·g -1 ) sorbent, sorption properties of compounds can be predicted using where P L /Pa and T b /K are the liquid vapor pressure and standard boiling point of a compound, respectively. To obtain the P L value of 1,2-DiCB at 20 °C, the Wagner-type equation with the parameters given by Roháč et al was used . For 1,2,4,5-TeCB and HCB, the solid vapor pressure P S values at 20 °C were first derived from regression of the logarithm of P S against reciprocal absolute temperature.…”
