| titleOfInvention | Bromine compound production method |
| abstract | A method for the production of a bromine compound comprising reacting in a reactor a compound having an aliphatic unsaturated bond represented by the following formula with bromine: wherein Ar1 and Ar2 may be the same or different and are each an aromatic hydrocarbon group having 5 to 16 carbon atoms or saturated alicyclic hydrocarbon group having 5 to 12 carbon atoms, the Ar1 and the Ar2 hydrocarbon groups can be substituted by at least one halogen; Y is a saturated hydrocarbon group having 1 to 6 carbon atoms, sulfone group, sulfide group, ketone group, alkylene oxide group having 2 to 6 carbon atoms or single bond; R1 and R2 may be the same or different and are each a hydrocarbon group having 2 to 11 carbon atoms having at least one aliphatic unsaturated group, to produce a bromine compound represented by the formula wherein Ar1, Ar2 and Y are the same as defined in the above formula (I), and R3 and R4 are groups obtained by saturating the unsaturated groups of R1 and R2 in the 3545 כ" ו בכסלו התשס" ג - December 1, 2002 above formula (I) with bromine, respectively, wherein the reaction is carried out in the presence of a solvent which is inactive in the reaction, and 80% or more of the theoretical amount of the heat generated by the reaction is removed from the reactor by the vaporization of the solvent. Also claimed as novel is a flame retardant composition comprising (i) a bromine compound in an amount of 90% by weight or more, of the formula wherein Ar1 and Ar2 may be the same or different and are each an aromatic hydrocarbon group having 5 to 16 carbon atoms or saturated alicyclic hydrocarbon group having 5 to 12 carbon atoms, the Ar1 and Ar2 hydrocarbon groups can be substituted by at least one halogen; Y is a saturated hydrocarbon group having 1 to 6 carbon atoms, sulfone group, sulfide group, ketone group, alkylene oxide group having 2 to 6 carbon atoms or single bond; R3 and R4 may be the same or different and are each a hydrocarbon group having 2 to 11 carbon atoms to which a bromine atom is added, and (ii) a hydroxy bromine compound represented by the following formula in an amount of 0.0001 to 0.02 mol% based on 1 mol of the bromine compound, wherein Ar1, Ar2 and Y are the same as defined in the above formula (I), R6 and R7 may be the same or different and are each a hydrocarbon group having 2 to 11 carbon atoms, p and q are each an integer of 0 to 10, provided that p+q is an integer of 1 or more, and s and t are each an integer of 0 to 5, provided that s+t is an integer of 1 or more. |
