Oxygen-absorbing resin composition
Oxygen-absorbing resin composition comprising a polyester containing a constitutional unit (a) comprising tetralin ring structure, for example, an alkyl tetralin dicarboxylate, wherein the alkyl component has, for example, from 2 to 6 carbon atoms, and a constitutional unit (b) derived from a polyfunctional compound, selected from glycerin, trimethylol propane, pentaerythritol, trimellitic acid, trimellitic acid anhydride, pyromellitic acid, and pyromellitic acid anhydride, and a transition metal catalyst.
System and method for deactivation and disposal of a pharmaceutical dosage form
A system and method are provided for deactivation and disposal of a pharmaceutical dosage form. The system and method employ an oxidant and an immobilizing agent placed in a container. The pharmaceutical dosage form is placed into the container, and water is added to the container. A rapid chemical deactivation of the active ingredient or ingredients in the pharmaceutical then occurs by a chemical oxidation process. Upon contact with the water, the immobilizing agent swells or expands in volume to form a gel or slurry, binding the other components in the container within the gel or slurry, where they remain after disposal. The system can be in the form of a kit, or can be scaled up for use by municipalities or institutions.
Catalysts based on amino-sulfide ligands for hydrogenation and dehydrogenation processes
The present application discloses novel amino-sulfide metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals.
