CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Hexaethyl tetraphosphate is a yellow liquid which is miscible in water. It is difficult to burn. It is toxic by skin absorption and inhalation. It is a mixture of ethyl phosphates and ethyl pyrophosphate. It decomposes at high temperatures. May be found in the form of a dry mixture where the liquid is absorbed onto a dry carrier. |
