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

摘要

The present invention relates to a mixture of at least one dialkylphosphinic acid of formula (I) and at least one dialkylphosphinic acid of formula (II). The invention further relates to a process for its preparation and its use. Formula I In the above formula (I), R ¹ , R ² are the same or different and represent C ₁ -C ₁₈ alkyl, C ₂ -C ₁₈ alkenyl, C ₆ -C ₁₈ aryl, C ₇ -C ₁₈ alkyl aryl. Formula II In formula (II) above, R ³ , R ⁴ are the same or different and represent C ₁ -C ₁₈ alkyl, C ₂ -C ₁₈ alkenyl, C ₆ -C ₁₈ aryl and / or C ₇ -C ₁₈ alkyl aryl At least one of the radicals R ³ and R ⁴ is different from R ¹ and R ² .
