    • 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.
    • 本发明涉及一种消除气体或液体中含有的有机磷化合物的方法,其中所述气体或液体与氧化铝和/或氧化钛接触。 根据本发明的一个方面,提供一种处理包含至少一个碳原子并包含在液体中的三价和/或五价有机磷化合物的方法。 该方法包括使液体与氧化钛和/或氧化铝接触,所述氧化铝具有至少70m 2 / g的比表面积和至少0.3cm 3 / g的总孔体积。 氧化铝和/或二氧化钛可以掺杂碱金属,碱土金属和/或稀土。 有机磷化合物可以包括膦,次膦酸盐,亚磷酸盐,亚膦酸盐,次膦酸盐和膦酸盐。 被处理的液体可以源于丙烯腈在含磷催化剂存在下的二聚反应,或者是在含有磷的催化剂存在下由丁二烯的氢氰化反应。
