Abstract
Bis(pentaerythritol phosphate) carbonate can be formed by the reaction of pentaerythritol phosphate alcohol and dihydrocarbyl carbonate, such as diphenyl carbonate, preferably in the presence of a transesterification catalyst, such as an imidazole, and in a high boiling organic solvent, e.g., a phosphate ester solvent, which allows for removal of by-product.
