A series of isooctyl alcohol phosphate esters were prepared under different reaction conditions to determine the correlation between the composition ratio of mono- and di-phosphate esters and the permeability of the product. The results showed that when the mole ratio of diester to monoester is 15 ~ 35, the permeability is the best. The optimum reaction conditions for the synthesis of isooctanol phosphate penetrant are as follows: the molar ratio of isooctanol and phosphorus pentoxide is 2 ~ 3, the reaction temperature is 70 ℃ and the reaction time is more than 3h. In leather tanning baths, the application of isooctyl phosphate penetrants and JFC penetrants were compared
