聚氨酯泡沫塑料常用于从水溶液或气相中分离或富集有机物质和无机物质.本文用气相色谱法测定了某些溶质在气相与聚氨酯相间分配过程的焓变、熵变和自由能变.由获得的实验数据估算了聚醚型和聚酯型泡沫塑料的溶解度参数。这些对于进一步研究聚氨酯泡沫塑料的吸收性能和在分析化学中的富集是很有用的.
Polyurethane foam is commonly used to separate or enrich organic and inorganic substances from aqueous solution or gas phase.In this paper, the enthalpy, entropy change and free energy change of some solutes in gas phase and polyurethane phase are determined by gas chromatography The experimental data estimated the solubility parameters of polyether and polyester foams. These are useful for further research on the absorption properties of polyurethane foams and their enrichment in analytical chemistry.
