Hydrolysis Of

Dehydrohalogenation of a mixture of glycerol 1,3- and 2,3-dihalohydrins by a strong basic ion-exchange resin (IRA 440 and A 26) at room temperature in an organic medium quantitatively leads to the corresponding epihalohydrin (1a; X = Cl), and (1b; X = Br) in a very short reaction time. Hydrolysis of the epihalohydrin does not occur under these conditions.

Abstract Carbonized ion exchange resin beads were prepared as catalyst for gas phase hydrogenation processes. Amberlite IR 120 polystyrene based sulfonated ion exchange beads were carbonized at 900 °C. The process of carbonization was monitored by FTIR combined thermogravimetric analysis. During the carbonization formed sulfur dioxide, carbon dioxide and organic compounds. The carbon pearls were used as catalyst support for Pd nanoparticles. The catalyst was characterized by scanning electron microscopy and X-ray diffractometry. The diameters of the palladium nanoparticles on the catalyst surface were between 15 and 50 nm, but bigger aggregates were also detected. The catalyst was tested during the gas phased heterogeneous catalytic hydrogenation of 1-butene. The hydrogenation process was followed by FTIR measurements, 93% conversion was reached after 10 min.

Dowex 1

Dowex-1 ion exchange resin beads bind indoleacetate, naphthaleneacetate, and indoleproprionate ions and release them to plant tissue. We suggest this tool shows considerable potential in assessing the role of growth substances in morphogenesis. Some properties of IAA loaded beads are described.
