The chemical synonyms of [3-Benzoyloxy-2,2-bis(benzoyloxymethyl)propyl] benzoate (CAS NO.4196-86-5) are 1,3-Propanediol,2,2-bis[(benzoyloxy)methyl]-,dibenzoate ; 2,2-Bis((benzoyloxy)methyl)dibenzoate-1,3-propanediol ; 3-Propanediol,2,2-bis((benzoyloxy)methyl)-dibenzoate ; 3-Propanediol,2,2-bis[(benzoyloxy)methyl]-dibenzoate;benzoflexs-552 ; Benzoicacid,tetraesterwithpentaerythritol ; Pentaerythritol tetrabenzoate ; Pentaerythritol tetrabenzoate 98+% .Toxicity - alcohols and polyols vary widely in toxicity. Among the most toxic are methyl and allyl alcohol, which act as nervous system depressants.When heated to decomposition pentaerythritol tetrabenzoate emits acrid smoke and irritating fumes. It can be used as solid plasticizer for PVC, but also as a processing aid to improve the rolling winding as well as access to better stability. |
