to form succinonitrile or propionitrile.No attempt was made to detect these.The methane yield was not affected by adding enough glacial acetic acid to the electrolysis solution to raise the acetic acid concentration to 0.5 . The initial concentration resulting from the acetic acid present in the tetrabutylammonium acetate crystals was 0.07M. 380 (1952).

The present paper describes a new technique for preparing the surface of polyethylene and polypropylene plastics for the adsorption of heparin. The procedure consists of exposing the plastic surface to a solution of cationic surfactants a t a temperature close to the softening temperature of the plastic. The mechanism of adsorption of the anticoagulant of the surfaces is discussed.
3H‐Atropin (Aktivität: 16.5 mC/mMol) und 3H‐Nor‐(–‐)‐cocain (Aktivität: 2.5 mC/mMol) wurden durch Einwirkung von Tritium‐Gas auf Atropin und Nor‐(–‐)‐cocain in einer dafür besonders entwickelten Apparatur dargestellt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
