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 phosphono paraffin represented by formula (I):
wherein each instance of R1 is independently —H or
wherein each instance of R2 and R3 is independently linear or branched C1-20 alkyl, C1-20 cycloalkyl, or aryl; the number of instances where R1 is
of formula (I) is between about 2 and about 8; and n is an integer between 4 and 22.
本文所述方面一般涉及制造膦基石蜡的方法,包括通过混合卤代石蜡、亚磷酸酯和碘化钠形成反应混合物。方法包括加热反应混合物以形成膦基石蜡。本文所述方面还涉及由式 (I) 表示的膦基石烷:
其中 R1 的每个实例独立地为-H 或
其中 R2 和 R3 的每个实例都独立地为线性或支链 C1-20 烷基、C1-20 环烷基或芳基; R1 的实例数为
式(I)中,n 是介于 4 和 22 之间的整数。
