Polarography in Molten Salts
TYPES OF MELTS From the practical viewpoint, melts may be classified according to melting points which may limit the available techniques. The lowest melting, with working temperatures up to 250°, are typified by the LiNO3—NaNO3— KNO3 eutectic, NaNO3—KNO3 eutectic, LiClO4, and ammonium formate. With these solvents it is possible to use the dropping mercury electrode, or hanging mercury drop ele...
متن کاملRapid-sweep polarography of cystine.
In their brochure The Principles and Applications of Cathode-Ray Polarography Southern Analytical Ltd. (Camberley, Surrey, U.K.) refer to a paper in which one of their cathode-ray polarographs is used for the determination of amino acids containing thiol and disulphide groups (Coult, 1958). This work apparently takes no account of the fact that the shape of a rapid-sweep polarogram is more depe...
متن کاملPolarography of diacetylthiamine and dibenzoylthiamine.
In recent years, a series of thiamine derivatives has been synthesized and many investigations have been made both chemically and medically. Allithiamine, a S-alkyl thiamine derivative, was studied in the previous pa per (1) and was found to have polarographically a similar behavior to thia mine. In the present experiment, polarographic investigations on diacetyl thiamine (DAT) and dibenzoylthi...
متن کاملEnzymatic Synthesis of Polynucleotides
Several publications from this laboratory have dealt in a preliminary fashion with the preparation and properties of highly purified polynucleotide phosphorylase from Azotobacter vinelan&i (2-4). A more detailed account of this work is presented in thii paper. Although polynucleotide phosphorylase preparations can catalyze the synthesis of a variety of homopolymers (polyadenylic acid, polyuridy...
