Mixtures of at least one dialkylphosphinic acid with at least one other dialkylphosphinic acid that is different therefrom, method for production thereof, and use thereof.
The invention relates to a mixture of at least one dialkylphosphinic acid of the formula (I)
in which
R1, R2 are the same or different and are each C1-C18-alkyl, C2-C18-alkenyl, C6-C18-aryl, C7-C18-alkylaryl,
with at least one different dialkylphosphinic acid of the formula (II)
in which
R3, R4 are the same or different and are each C1-C18-alkyl, C2-C18-alkenyl, C6-C18-aryl and/or C7-C18-alkylaryl,
with the proviso that at least one of the R3 and R4 radicals is different than R1 and R2.
