In the previous paper the rust-preventive properties of several alkylphosphonic acid derivatives were examined, and authors reported that 9 (10) -phosphonostearic acid had the good properties.
In this paper the properties of 9 (10) -phosphonostearic acid were compared with that of other 9 (10) -substituted stearic acids, such as 9 (10) -carboxy-, 9 (10) -hydroxy-, 9 (10) -mercapto- and 9 (10) -amino-stearic acids, by the potassium ferricyanide test, salt water immersion test and humidity cabinet test. As a result it was found that 9 (10) -phosphonostearic acid had the more surpassing properties than the others.
