The complex contains at least one, pref. 4, chemically bound ROH molecule where R is either H or and organic radical. R is pref. an opt. subst. aliphatic hydrocarbon (C1-C4), specif. ethyl alcohol. The halohen can be Cl, Br, Ti; the atomic ratios of both P and halogen to aluminium being near 1:1. If both water and alcohol are present the number of molecules is pref. 2-5. Specific compounds claimed have empirical formulas: AlPBrH25-C8O8, AlPBrH28C8O8, AlPClH11O9, AlPClH25C8O8 the compounds are prepared from Al-compounds (halides), hydroxy compound and phosphoric acid, -ester or a compound generating the acid or ester. |
