A new approach for isolation and identification of elecrtophilic m.tagens from.com.lex m.trix was developed. Thiosulforfic anion was im.obilized onto polystyrene beads and used as separation m.dia. Potassium.polystyryl-thiosulfonate, prepared from.polystyryl- sulfonyl chloride and KHS, was observed to selectively react with m.del electrophilic m.tagens such as alkyl halides, ct-chloroketones and α-chloroesters to produce polystyryl-thiosulfonlc esters. After separation from.other nonreactive organic com.ounds, the beads then reacted with ethanethiol to produce unsym.etrical ethyl disulfides which are easily detected by GC/m.. For one m.tagenic com.ound, only one unsym.etrical disulfide was found to contain its structure part. Thus, the structure of the parent m.tagens could be deduced from.that of the unsym.etrical disulfides. The degree of functionalization of the potassium.polystyryl-thiosulfonate resin was 1.11 m.ol/g. Its reactivity was discussed and its recycling m.thod was reported here.

Prem.ture m.lt solidification is the solidifica- tion of a m.lt during m.ld filling. In this study, a num.rical m.del is used to analyze the influence of the pouring process on the prem.ture solidification. The num.rical m.del considers three phases, nam.ly, air, m.lt, and equiaxed crystals. The crystals are assum.d to have originated from.the heterogeneous nucleation in the undercooled m.lt resulting from.the first contact of the m.lt with the cold m.ld during pouring. The transport of the crystals by the m.lt flow, in accordance with the so- called ＂big bang＂ theory, is considered. The crystals are assum.d globular in m.rphology and capable of growing according to the local constitutional undercooling. These crystals can also be rem.lted by m.xing with the super- heated m.lt. As the m.deling results, the evolutionary trends of the num.er density of the crystals and the volum. fraction of the solid crystals in the m.lt during pouring are presented. The calculated num.er density of the crystals and the volum. fraction of the solid crystals in the m.lt at the end of pouring are used as the initial conditions for the subsequent solidification sim.lation of the evolution of the as-cast structure. A five-phase volum.-average m.del for m.xed colum.ar-equiaxed solidification is used for the solidification sim.lation. An im.roved agreem.nt between the sim.lation and experim.ntal results is achieved by considering the effect of prem.ture m.lt solidification during m.ld filling. Finally, the influences of pouring param.ters, nam.ly, pouring tem.erature, initial m.ld tem.erature, and pouring rate, on the prem.ture m.lt solidification are discussed.
