Quantitative semimicro inorganic procedures
(Elsevier, 1951)
Representative volumetric, gravimetric, and electrolytic determinations, many on "practical" samples of alloys or minerals, have been applied on a semimicro level. The use of classical microchemical apparatus, which is ...
Polarographic reduction of uranium(VI) under complexing and noncomplexing conditions nature of the uranium(V) sulphate complex
(Elsevier, 1959-10)
The polarographic reduction of U(VI) to U(V) in acid solution is sensitive to both type and concentration of anion present. Consequently, the reduction was studied using perchlorate as a non-complexing anion and sulphate ...
Versuche zur Synthese des Cytisins. Dehydrierung von Tetrahydro-cytisin zu Cytisin
(Springer-Verlag, 1954-09)
Die Dehydrierung von Tetrahydro-cytisin zu Cytisin mit Palladium verläuft glatt, wenn man die Iminogruppe durch Acetylierung schützt. Durch Erhitzen des N-Acetyl-tetrahydrocytisins mit Pd-Mohr bei 280° erhält man so in ...
