                                Chemical Name:Trisodium pyrophosphate、Acid trisodium pyrophosphate、Trisodium

                                monohydrogen diphosphate

                                Formula: Na3HP2O7Anhydrous)、Na3HP2O7·H2OMonohydrate

                                Molecular weight: 243.92Anhydrous

                                CAS: 14691-80-6

                                Properties:

                                White powder crystal, soluble in water, water solution near neutral, insoluble in ethanol.It often exists in the form of a hydrate (Na3HP2O7·H2O) and the crystal water is not easily removed.

                                When heated to above 170 ℃, it can be broken down slowly into sodium acid pyrophosphateand sodium pyrophosphate; when more than 240 ℃ ,it is decomposed into metaphosphate.

                                 

                                Specifications:
