Process for preparation of dibromopropyl ether compound having high melting point |
| abstract |
A process for the preparation of a dibromopropyl ether compound having a high melting point, which comprises mixing a bis-dibromopropyl ether of tetrabromobisphenol-sulfone or tetrabromobisphenolpropane represented by the following general formula: <IMAGE> <IMAGE> in the melted state with a crystallized product of said compound at a temperature lower than the melting point of the crystallized product, and holding the mixture at a temperature of 50 DEG to 100 DEG C. According to this process, the dibromopropyl ether compound of a high melting point can be prepared without using an organic solvent. |
