Dibal C 102







Dibal C 102-H is a dimer with a hydrodynamic radius of about 2.22 nm. 1. Synthesis of molecular DIBAL C 102-H DIBAL C 102-H and DIBAL C 102 were obtained by the reductive elimination of the tetrahedral complexes [1]+[C102-H]− or [1]+[C102]− by DIBAL-H. The alkylated-polysiloxane adsorbent was prepared by reaction of tetrahedral disiloxane 2 with a trialkylsilylalkyl silane in the presence of DIBAL C 102-H as the reducing agent at room temperature. The adsorption of acetone and isoprene on these polysiloxane adsorbents was studied under dynamic conditions. Use of new, commercially available adsorbent with Lewis acidic sites allows to carry out the most convenient industrial chromatographic process for the separation of acetone and isoprene mixtures in a short time.
