    摘要: The efficient production of poly(tetramethylene ether) diacetate [PTMEA] or other diesters, from tetrahydrofuran [THF] is obtained utilizing an acid-based catalyst that is based on a morphologically reconfigured and Bronsted acidity enhanced halloysite derived from a preparation method of using naturally occurring halloysites. More specifically, the method relates to morphological modification of the internal pore structure of halloysites via supercritical carbon dioxide treatment directly applied onto the raw halloysite minerals, that yields highly synergistic and reproducible results of elimination of inaccessible and detrimental extra-small pores. PTMEA is readily converted to poly(tetramethylene ether) glycol (PTMEG) by a transesterification reaction

    摘要: The resin solid acid is a sulfo group-modified resin obtained by introducing sulfo groups into a raw material resin in an uncarbonized state, the yield of the sulfo group-modified resin based on the weight of the uncarbonized raw material resin is 80% or more, the amount of sulfo groups in the sulfo group-modified resin is 1 mmol/g or more, and the raw material resin is in the form of a powder, granules or fibers. In addition, the method for producing the resin solid acid is a production method for obtaining a sulfo group-modified resin by comprising a step for adding a sulfonating agent in the form of any of sulfuric acid, fuming sulfuric acid or chlorosulfonic acid to a raw material resin in an uncarbonized state, and a step for heating the uncarbonized raw material resin at 200° C. or lower.
