Linear solvation energy relation was firstly introduced in the paper, and the method and step of gaining the special parameters of solvent and solute were introduced in detail, and these special parameters were used to selection and optimization of extractive agent in extractive distillation. The model of predicting activity coefficient at infinite dilution was established by linear solvation energy relation. By the above theory, several candidate solvents were selected to separate C5 fraction, and by experiment of vapor-liquid phase equilibrium at atmosphere pressure, the mixture of N-methyl-pyrrolidone including 4% water was used extractive agent of separating C5 fraction. Then binary vapor-liquid phase equilibrium of the some compound in C5 fraction and N-methyl-pyrolidone were determined at atmosphere pressure and correlated by NRTL equation. Isoprene being objective compound, experiments were operated in the laboratory-scale column; the processes were simulated by RadFrac model in ASPEN PLUS. And by the combination of experiment and simulation, the new process of separation of C5 was established.

At the same time, Convergence Technologies Limited announced the formal termination of the G1x8 product which was exclusive for Dynatron Corporation. In 2008, Convergence Technologies Limited completed development of an aluminum-finned vapor chamber cooler for 1-U server applications, which began shipment to Dynatron under the product code of G1x8. On September 19th, Convergence became aware of Dynatron publicly selling a replacement vapor chamber cooler with copper fins called G218, and dissections revealed it to possess the same allegedly infringing features as parts manufactured by Taiwan Microloops Corporation.
