摘要： The invention is a process for preparing a solid, storage-stable tris(bromophenyl)phosphate ester by the phosphorylation of a bromophenol and recovering the product by cooling a solution of the reaction mixture from a hydrocarbon solvent containing 2 to 20 parts of a C5 to C10 alkane per part of a C6 to C10 arene.
