Note sur la préparation et la scission de l'acide (diméthyl-3, 3-butyl)-phosphorique

3,3-Dimethylbutanol treated with polyphosphoric acid or with an equimolecular amount of POCl₃ gives rise to 3,3-dimethylbutyl phosphoric acid, isolated as baryum salt (yield 20 to 30%) or as sodium salt (yield 15%). Stable in NaOH 1N at 100°C, this monoester is split at pH 4.5 and in HCl 1N much slower than choline phosphate.
