  • Patent number: 8327856
    Abstract: An environmentally degradable cigarette filter includes a filter element of a bloomed cellulose acetate tow and a plug wrap surrounding said filter element. A weak organic acid and a pH adjusted inorganic ester salt are encapsulated in a matrix material which is in contact with the tow. The pH adjusted inorganic ester salt has a pH less than or equal to 8. When the cigarette filter is discarded into the environment, water liberates the weak acid and the ester salt from the matrix material. The weak acid hydrolyzes the ester liberating a strong acid. The strong acid catalyzes the degradation of the cellulose acetate tow. (The weak acid also hydrolyzes the cellulose acetate tow, but after the strong acid is generated, the strong acid becomes the dominant acid catalyst for the cellulose acetate tow degradation.

  • Patent number: 8309662
    Abstract: A process for producing a solution blend of a polybenzimidazole (PBI) and a polyetherketoneketone (PEKK). The PBI is mixed with sulfuric acid at a temperature between 40° C. and 80° C. for 30 minutes to 2 hours to produce a PBI solution then cooled to room temperature to form a cooled PBI solution. Then PEKK is added to the cooled PBI solution to form a mixture and that mixture is stirred from 30 minutes to 2 hours at room temperature to form a stirred mixture. The stirred mixture is poured into an excess of water being stirred swiftly to form an aqueous mixture. The aqueous mixture is filtered to produce a blend. The blend is washed with water and dried. The resulting blend can yield a blend in all proportion from 1/99 PBI/PEKK to 99/1 PBI/PEKK.

  • Patent number: 8241388
    Abstract: The invention is a process for treatment of brown grease, where the brown grease comprises water, food solids and free-oil. This process starts with the collection of the brown grease into a container. The brown grease's pH is adjusted with a chemical treatment to produce an adjusted brown grease phase. To the adjusted brown grease phase an anionic copolymer treatment mixture is added along with a cationic copolymer to form a reaction mixture. The reaction mixture reacts for a period of time, and during this time wastewater is discharged from the reaction mixture to produce resulting solids. The resulting solids are then transferred from the container for disposal or are processed further into a fuel or soil additive.

  • Patent number: 8227609
    Abstract: A process for purifying plant extracts which consist essentially of noroxymorphone compounds and which comprise, as impurities, ?,?-unsaturated noroxymorphone compounds, by (a) converting the plant extract or the product of a subsequent stage in the synthesis of a selected noroxymorphone compound in a reaction which converts the hydroxyl groups present in the mixture to leaving groups of the formula —OR2 in which R2 is the introduced radical of the leaving group, (b) these leaving groups are optionally detached again, then (c) the resulting mixture is subjected to a selective hydrogenation, so that a saturated bond is formed in the ?,?-position of the unsaturated noroxymorphone compounds and any remaining leaving groups are each converted to a hydroxyl group and then optionally (d) the pure noroxymorphone compound is isolated; processing of the noroxymorphone purified in this way to naltrexone or naloxone or a salt of these compounds or a quaternary derivative of these compounds; pharmaceutical formulations c
