Synthesis
(1), Sulfated neat’s foot oil is obtained by esterification of neat’s foot oil and concentrated sulfuric acid;
(2), Sulfated neat’s foot oil sodium salt is obtained by neutrallzation of sulfated neat’s foot oil and sodium hydroxide solution.
Also may refer to the preparation of sulfated castor oil.
