Synthesis of Long-Chain n-Alkylphosphonic Acids by Phosphonylation of Alkyl Bromides with Red Phosphorus and Superbase under Micellar/Phase Transfer Catalysis

Long-chain n-Alkylphosphonic acids, AlkP(O)(OH)2, are synthesized in up to 91 % yield (mostly 40–60 %) by straightforward phosphonylation of alkyl bromides (AlkBr, Alk=C4–C18) with red phosphorus (Pn) in the multiphase KOH/H2O/toluene system in the presence of 2–10 mol % of cetyltrimethylammonium bromide (CTAB), acting as a micellar/phase transfer catalyst and as a generator/transporter of superbasic hydroxide anions, the intermediate potassium phosphinates being in situ oxidized/neutralized by nitric acid. The key steps of the phosphonylation mechanism are the P?P bond cleavage of Pn polymeric molecules by superbasic ?OH anions, dissolved in the CTAB micelles, and phase transfer of polyphosphide anions to the organic phase and their alkylation with AlkBr.

Chemical modification of alumina and silica with alkylphosphonic acids and their esters

Alumina and silica were modified with alkylphosphonic acids and diethyl butylphosphonate. The boundaries of hydrolytic stability of the obtained surface-modified materials were determined.

Process for the production of aliphatic phosphonic acids

An improvement in the process for the manufacture of aliphatic phosphonic acid the improvement comprising maintaining the reaction zone volume at about 80 to 95 percent capacity of reactants and/or products by continuously adding diester of aliphatic phosphonic acid reactant up to about 60 percent of the total reaction time said reactant being added in an amount sufficient such that said reactants and/or products will always be present in said reactor so as to occupy at least 80 percent of the reaction zone volume during said reactant addition.

Process for preparing phosphonic acids
