Automated Monitoring of the Establishment of the Adsorption Equilibrium: Adsorption of Polyethylene from 1,2,4-Trichlorobenzene onto a Zeolite at Temperature C
Figure 2
(a) Decrease of the IR detector response with time after the addition of the zeolite SH-300 to solutions of polyethylene with an average molar mass of 2.155 kg/mol in 1,2,4-trichlorobenzene. Temperature: 139-140. Symbols: initial mass of polyethylene in the reactor: ●—7.70 mg; ■—11.20 mg; ▲—15.30 mg; ▾—20.64 mg; ◆—31.14 mg. (b) Decrease of the IR detector response with time after the addition of the zeolite SH-300 to solutions of polyethylene with an average molar mass of 14 kg/mol in 1,2,4-trichlorobenzene. Temperature: 139-140°C. Symbols: initial mass of polyethylene in the reactor: ■—4.8 mg; ●—10.5 mg; ▲—21.2 mg; ▾—26.1 mg; ◆—30.39 mg. (c) Change of the response of the IR detector with time after the addition of zeolite SH-300 to solutions of polyethylene with an average molar mass of 53.1 kg/mol in 1,2,4-trichlorobenzene. Temperature: 139-140°C. Symbols: initial mass of polyethylene in the reactor: ■—6.44 mg; ●—11.28 mg; ▲—16.64 mg; ▾—22.35 mg; ◆—30.22 mg.
