Abstract
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.
Claims29
A method of making a secondary phosphono paraffin, comprising:
- mixing
- (i) a secondary haloparaffin,
- (ii) a phosphite, wherein a molar ratio of phosphite to secondary haloparaffin is from about 1:1 to about 10:1, and
- (iii) one or more of sodium iodide, potassium iodide, or potassium bromide to form a reaction mixture, wherein a molar ratio of the sodium iodide, potassium iodide, or potassium bromide to secondary haloparaffin is from 1:1 to about 10:1;
- and
- heating the reaction mixture to form a secondary phosphono paraffin at an overall yield of from about 20% to about 80%.
