    Abstract: The invention relates to a process for preparing pentabromobenzyl acrylate through the reaction of pentahalobenzyl halide with a salt of acrylic acid in water-immiscible solvent, wherein said salt is in aqueous form and the reaction is carried out in the presence of a phase transfer catalyst. A process for polymerizing the pentabromobenzyl acrylate in halogenated aromatic solvent and the poly (pentabromobenzyl acrylate) obtained are also disclosed.

    Abstract: The present invention relates to an improved process for the manufacture of purified phosphoric acid from phosphate rock. According to the invention, phosphate rock is decomposed by a mineral acid selected from hydrochloric acid, sulfuric acid or mixtures thereof. The dissolution liquor obtained is reacted with a calcium-containing compound such as calcium oxide, calcium carbonate, tricalcium phosphate and fines of phosphate rock producing an aqueous solution containing monocalcium phosphate in an amount corresponding to between 0.4% to 5.5% by wt CaO. After the separation of the precipitated solids, the clarified solution is extracted by an organic solvent having the property to extract the phosphate component. The phosphoric acid is subsequently recovered from the solvent extract by known methods such as washing or distillation.
