摘要： The invention concerns a method for eliminating organophosphorus compounds contained in a gas or liquid whereby said gas or liquid is contacted with alumina and/or titanium oxide. According to one aspect of the present invention, a process is provided for disposing of a trivalent and/or pentavalent organophosphorus compound which comprises at least one carbon atom and is contained in a liquid. The process comprises contacting the liquid with titanium oxide and/or alumina, the alumina having a specific surface of at least 70 m2/g and a total pore volume of at least 0.3 cm3/g. The alumina and/or titanium dioxide can be doped with alkaline metals, alkaline-earth metals and/or rare earths. The organophosphorus compound can include phosphines, phosphinites, phosphites, phosphonites, phosphinates and phosphonates. The liquid which is treated can originate from a dimerization reaction of acrylonitrile in the presence of catalysts containing phosphorus, or from a hydrocyanation reaction of butadiene in the presence of catalysts containing phosphorus.
