Process for the adsorption of chelated organometallic compounds adsorbent to the alumina base and use of the adsorbents to the alumina base

摘要

The process for adsorbing organometallic chelate cpds. comprises contacting the cpds. with an aluminium adsorbent formed by coagulation, extrusion or grinding and having a volume of pores with a dia. greater than 80 Angstrom of 0.15 cm3/g and a granular size of less than 4 mm. Also claimed is the aluminium adsorbent comprising an organometallic chelate obtd. after contacting with the organometallic cpd..
