CATALYSIS OF NUCLEOPHILIC CLEAVAGE OF PHOSPHONATES So that a large number of catalysts and catalyst combinations could be studied rapidly and exactly, hydrolysis of a simple compound such as diethyl methylphosphonate was followed. Results indicated that neither catalysis by acids or bases were readily observable for this reaction, where the attacking nucleophile is a hydroxide ion. REARRANGEMENT OF HYDROXAMIC ACIDS p-Phenylazo-benzohydroxamic acid was prepared from the commercially available acid chloride, p-C6H5-NN- C6H4-COCl. Unsuccessful attempts were made to prepare p-p-nitrophenylazo benzohydroxamic acid. A STUDY OF THE PRACTICAL SENSITIVITY LIMITS OF CERTAIN TRACE DETECTION TECHNIQUES A survey was made of existing electrochemical and electronic detection techniques. Coulometry in moderate volumes of solution and direct gas phase ionization current measurement appear to be superior techniques.
