摘要:
Aliphatic and aromatic esters of polybrominated dipentaerythritol such as, for example, the diacetate of tetrabromodipentaerythritol, the diacetate of dibromodipentaerythritol and the dibenzoate of tribromodipentaerythritol are described. The esters are prepared by hydrobrominating dipentaerythritol at about 100* to about 140*C. in the acid which is to be used for esterification. The esters are useful as flameproofing agents for synthetic resins.
