Aspects described herein generally relate to methods of making a phosphono paraffin comprising forming a reaction mixture by mixing a haloparaffin, a phosphite, and sodium iodide. Methods comprise heating the reaction mixture to form the phosphono paraffin. Aspects described herein further relate to a (see formula I) phosphono paraffin represented by formula (I): (see formula I) wherein each instance of R3 is independently ¨H or ; wherein each instance of R1 and R2 is independently linear or branched C3-20 alkyl, C1-20 (see formula I) cycloalkyl, or aryl; the number of instances where R3 is of formula (I) is between about 2 and about 8; and n is an integer between 4 and 22. Des aspects ci-décrits concernent généralement des méthodes de fabrication de phosphono-paraffine comprenant la formation dun mélange de réaction en mélangeant une haloparaffine, un phosphite et un iodure de sodium. Des méthodes comprennent le chauffage du mélange de réaction pour former la phosphono-paraffine. Les aspects ci-décrits concernent également une phosphono-paraffine représentée par la formule (I) : chaque instance de R3 est indépendamment ~H ou; chaque instance de R1 et R2 est indépendamment un alkyle en C3-C20 linéaire ou ramifié, un cycloalkyle en C1-C20 ou un aryle; le nombre dinstances selon lesquelles R3 est de formule (I) est denviron 2 à environ 8; et n est un nombre entier entre 4 et 22.
