| Research Abstract |
We studied the aqueous solubility of terephthalic acid(TPA), which was determined using a flow apparatus and the saturated liquid compositions were analyzed by a total organic carbon analyzer. Also we studied the depolymerization of poly(buthylene terephthalate)(PBT) resin, which is a copolymer of TPA and 1, 4-butanediol(1, 4-BDO), in high-temperature liquid water for the development of green chemical recycling system. TPA and tetrahydrofuran(THF) were obtained by the treatment of PBT in water at above 498 K. From the results of the treatment of 1, 4-BDO in water, we propose that THF was produced by the dehydration of 1, 4-BDO, which could be enhanced by the proton from TPA. In addition, we report the energy balance for the production of TPA and THF from PBT in high-temperature liquid water.
