Abstract: Ethylene oxide (EO) adducts of di- ard tri-functional starters, such as, trimethylolpropane and glycerine, provide unexpected improvements in the "wet compression set" properties of high resilience (HR) urethane foams. Heretofore, wet set improvements have been achieved through the use of EO adducts of tetrols because of the high degree of crosslink density which these materials impart to a urethane polymeric composition. One commercial wet set additive, which is an EO adduct of pentaerythritol and diglycerine, is an effective wet set improver. Surprisingly, EO adducts of di- and tri-functional starters provide improvements in foam wet set properties, which are comparable to those obtained with such commercial wet set additive. Specifically, EO adducts of glycerine in the 500 to 10,000 molecular weight range yield foam wet set improvements equal to those of such commercial wet set additive at as low as 20 percent of the use level on an equivalent weight basis. Moreover, the EO adducts of glycerine yield foams having improved elongation properties and improved processing (stability) characteristics as compared to those observed with such commercial wet set additives. An EO adduct of glycerine having a number average MW of 1,000 is particularly useful in the invention.

Abstract translation: 二元三官能起始物（如三羟甲基丙烷和甘油）的环氧乙烷（EO）加成物在高弹性（HR）聚氨酯泡沫的“湿压缩永久变形”性能方面提供了意想不到的改进。 迄今为止，由于这些材料赋予氨基甲酸酯聚合物组合物的交联密度高，所以通过使用四元醇的EO加合物已经实现了湿定型改进。 一种商业湿定型添加剂，它是季戊四醇和二甘油的EO加合物，是一种有效的湿定型改良剂。 令人惊讶的是，二官能和三功能起始机的EO加合物提供了泡沫湿固化性能的改进，这与用这种商业湿固定添加剂获得的那些相当。 具体地说，甘油在500至10,000分子量范围内的EO加合物产生等于这种商业湿定型添加剂的泡沫湿固化改进，其用量低于当量重量的20％。 此外，与使用这种商业湿定型添加剂观察到的那些相比，甘油的EO加合物产生具有改善的伸长性能和改进的加工（稳定性）特性的泡沫。 数均分子量为1,000的甘油的EO加成物在本发明中是特别有用的。

Abstract: This invention relates to a process for separating epsilon caprolactam from a feed mixture comprising epsilon caprolactam and one or more epsilon caprolactam isomers selected from the group consisting of 4-ethyl-2-pyrrolidinone, 5-methyl-2-piperdinone, 3-ethyl-2-pyrrolidinone and 3-methyl-2-piperdinone or octahydrophenazine which process comprises contacting under adsorption conditions said mixture with an adsorbent, selectively adsorbing said epsilon caprolactam isomers or octahydrophenazine to substantial exclusion of said epsilon caprolactam, removing the non-adsorbed portion of the feed mixture from contact with the adsorbent, and thereafter recovering high purity epsilon caprolactam. The epsilon caprolactam isomers or octahydrophenazine can be recovered by desorption under desorption conditions. The process can be conducted in a batch or semi-batch manner or in a continuous manner using moving bed or simulated moving bed technologies.
