There is provided herein a process for the preparation of aluminum salts of phosphonic acid esters by reacting phosphonic acid diesters with aluminum hydroxide in the presence of a catalyst. The catalyst is selected from the group consisting of a phase transfer catalyst, a thermally stable tertiary amine having a boiling point higher than about 140°C, a thermally stable tertiary phosphine having a boiling point higher than 140°C and combinations thereof. The aluminum phosphonates prepared can be used for making flame retarded thermoplastic polymers.

chloride and dimethylphosphate. We used solvatochromic probes to calculate the descriptors of IL–DMSO (at fixed DMSO mole fraction of 0.6; 40 °C), and correlated ET(probe) with the other descriptors. We also tested the correlations by using a molar volume of the IL (VM) instead of SD, and the Lorentz–Lorenz refractive index function f(n) of the IL–DMSO mixture instead of SP. The quality of the regression

A dihaloorganosilane is represented by the formula (I): Each X independently represents C1, Br, or I. Each Ar1 independently represents a phenylene group optionally substituted by 1 to 4 alkyl groups selected from methyl or ethyl. Each R1 independently represents an alkylene group having from 2 to 18 carbon atoms. Each R2 independently represents methyl or ethyl. Each R3 independently represents an alkylene group having from 1 to 18 carbon atoms. Each R4 independently represents an alkylene group having from 2 to 18 carbon atoms, and n is an integer in a range of 0 to 5, inclusive. Ionic organosilanes preparable from the dihaloorganosilanes are represented by the formula (II): Membrane compositions and membranes containing the ionic organosilanes are also disclosed.
