Amperometric titrations. III. The location of the minimum in amperometric titrations with regard to the equivalence point

Autor: I. M. Kolthoff, H. A. Laitinen

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 59:922-928

1. When in an amperometric titration the precipitate has the composition AB, A and B being reducible at the applied e.m.f. and yielding diffusion currents and when the diffusion current constants of A and B are different the location of the minimum c

Quantitative analysis of the compounds in synthesis mixtures of 2,2-dimethyl-3-hydroxypropionaldehyde by RP-HPLC and GC

Autor: T. Saarela, H. Hakanpää-Laitinen, E. Koivusalmi, E. Haatainen, I. Kilpeläinen

Publikováno v: Chromatographia. 52:22-26

RP-HPLC and GC methods are described for the determination of the compounds in synthesis mixtures of 2,2-dimethyl-3-hydroxypropionaldehyde (DHPAL). Special attention is paid to the analysis of DHPAL. Conditions for analysis are developed so that no d
