A method for producing acetaminophen may include causing p-nitrophenol to undergo an acetamination reaction to produce the acetaminophen, by passing a solution containing the p-nitrophenol through a column packed with a catalyst while also passing an acetylating agent and hydrogen through the column. The catalyst may be a supported metal catalyst in which a metal element is supported on a synthetic adsorbent, and a reaction temperature of the acetamination reaction is 0° C. to 60° C., and a reaction pressure of the acetamination reaction is 0.1 MPa to 1 MPa. With the method, it is possible to continuously produce acetaminophen safely and inexpensively with high selectivity and good yield, at a low reaction temperature and a low reaction pressure.

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.
