Studies on Hydroxamic Acids. Part VII. Preparation, Properties and Analytical Application of Thorium (lV) N-m-Tolyl-m-Nitrobenzohydroxamate

Department of Chemistry, Government Polytechnic, Ujjain (M.P.) Manuscript received 28 June 1976, revised 17 January 1977, accepted 10 February 1977 A new complex of thoriam(IV) with N-m-tolyl-m-nitrobenzohydroxamic acid was prepared by reacting an aqueous solution of Th with an alcoholic solution of N-m-tolyl-m-nitrobenzohydroxamic acid at 60o and adjusting the pH 4-4.5. The infrared spectra and thermal analysis of the complex have been discussed. The use of N-m-T-NBHA. for gravimetric determination of thorium. is described
