    Abstract: Solid-state highly brominated compounds such as solid brominated flame retardants with bromine contents of at least about 60 wt % often contain occluded bromine. Because of their high bromine contents, such compounds have relatively low solubility in common organic solvents. Despite this low solubility, the content of occluded bromine in such solid brominated compounds is effectively reduced by agitating a concentrated agitated slurry of the compound in an inert solvent at a suitable temperature for at least about 1 hour. Thereafter, solids with reduced content of occluded bromine are isolated or recovered from the slurry. Novel products having substantially reduced or eliminated occluded bromine contents and other very desirable characteristics are also provided.

    Abstract translation: 固态高度溴化的化合物，例如溴含量至少约60wt％的固体溴化阻燃剂通常含有阻塞的溴。 由于溴含量高，所以这些化合物在常见的有机溶剂中的溶解度相对较低。 尽管这种低溶解度，但是通过在惰性溶剂中在合适的温度下搅拌化合物的浓缩的搅拌浆料至少约1小时，可以有效地降低这些固体溴化化合物中封闭的溴的含量。 此后，从浆液中分离或回收含有减少的阻塞溴含量的固体。 还提供了具有显着降低或消除了阻塞的溴含量和其它非常理想特性的新产品。

    Abstract: A method for the selective reduction of an aromatic compound. The present invention provides a method for pre-venting the reduction of at least one halogen substituted aromatic ring of an aromatic compound, while allowing the reduction of at least one functional group on the aromatic compound. In the present invention at least one hydroxyl group is placed on the at least one halogen substituted aromatic ring to be protected from reduction. The aromatic compound is then reacted with at least one alkali metal in at least one nitrogen containing base and at least one alcohol at a ratio of the alcohol to the nitrogen containing base at which the aromatic ring with the hydroxyl group is protected from reduction, while the desired functional group is reduced.

    Abstract: This invention relates to a process for the preparation of 1,1-difluoroolefins, e.g., difluorovinyl cycloaliphatic compounds such as difluorovinylcyclohexane and derivatives by the dehydrofluorination of a trifluoromethyl-substituted cycloaliphatic compound and the resulting compositions. This method utilizes a “sterically hindered super-base” system represented by the formula M+−NRR−; where M is Na or K and R is a secondary, or tertiary alkyl or cycloalkyl group of amines for effecting dehydrofluorination of the trifluoromethyl group leading to the difluorovinyl based cycloaliphatic compounds. The sterically hindered super base can be formed by the, in situ, reaction of a sodium or potassium alkoxide, e.g., KtBuO with a lithium dialkylamide where the lithium is bonded to nitrogen atom of an amine bearing secondary or tertiary aliphatic groups.
