    • This invention relates to a process for the nitration of organic compounds, especially aromatic compounds, which comprises contacting said compound with a nitrating agent at conditions whereby a nitrated product is formed. The nitration agent and the compound are substantially separated by means of a polymeric membrane, said polymeric membrane preferably comprising sulfonic acid groups, pendant to the polymeric backbone. In a most preferred embodiment, the membrane is a perfluorosulfonic acid polymer. The use of this most preferred polymeric material as a membrane in the instant process allows the nitration of aromatic organic compounds to take place without the incorporation of strong sulfuric acid in the nitrating agent.
    • 本发明涉及硝化有机化合物,特别是芳族化合物的方法,其包括在形成硝化产物的条件下使所述化合物与硝化剂接触。 硝化剂和化合物通过聚合物膜基本上分离,所述聚合物膜优选包含垂饰于聚合物主链的磺酸基团。 在最优选的实施方案中,膜是全氟磺酸聚合物。 在本方法中使用这种最优选的聚合物材料作为膜,可以在不在硝化剂中引入强硫酸的情况下进行芳族有机化合物的硝化。

    • This invention relates to conversion processes which take place in the presence of solid acid catalysts, e.g., hydrocarbon conversion processes. More specifically, this invention relates to a process for the alkylation of organic compounds, preferably aromatic and paraffinic hydrocarbons, with alkylating agents, e.g., alkyl chlorides, alkyl sulfonates, alkyl epoxides, alkynes, etc., in the presence of a polyfluorosulfonic acid catalyst. In one preferred embodiment of the instant process the selectivity to the monoalkylated reaction product of said organic compound and said alkylating agent is maximized by (1) refluxing a mixture comprising said compound and the alkylated derivative thereof, (2) separating from the mixture of step (1) an overhead product comprising said organic compound, said overhead product being substantially free from said alkylated derivatives, (3) condensing said overhead product, (4) contacting said condensed overhead product with said alkylating agent in the presence of a polyfluorosulfonic acid catalyst, at conditions whereby a portion of said organic compound is reacted to form the alkylated derivative thereof, and (5) returning the resultant mixture of the organic compound and its alkylated derivative to the refluxing mixture of step (1). Fresh organic compound may be continuously added to said refluxing mixture while continuously withdrawing said alkylated derivatives. Preferably said organic compound is benzene and said olefin is selected from the group consisting of ethylene and propylene.
