| 摘要 |
The invention relates to a method for producing salts of dialkylphosphinic acids, characterised in that a) alkylphosphonous acid and/or hypophosphorous acid and/or their alkali salts are reacted with olefins in the presence of a radical starter to form dialkylphosphinic acids and/or their alkali salts and b) the dialkylphosphinic acids and/or their alkaline salts obtained according to a) are reacted with metal compounds of Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na and/or K to form dialkylphosphinic acid salts of the metals. The invention also relates to the use of the dialkylphosphinic acid salts of metals obtained according to the inventive method for producing flameproofing agents.
