Abstract
Esters of high gravity are made from castor oil by partially "splitting" the glycerides contained in the oil, removing the glycerine thus formed and heating the residue to form new esters. For example, castor oil is heated with a mixture of sulphuric acid and a fatsplitting agent until the mixture attains an acid value of 80 to 120. After settling, the lower layer containing sulphuric acid and glycerine is drawn off, and the upper layer containing fatty acids and glycerides is washed with water and heated under reduced pressure to 482 DEG F. until esterification is complete. In the final stage the temperature may be raised to 575 DEG F., and if necessary a small amount of raw castor oil is added to remove traces of free acid remaining. During esterification, dehydrating agents, inert gases or catalysts such as tin or zinc may be added.ALSO:A process for rendering castor oil miscible with mineral oil, consists in partially "splitting" the glycerides contained in the oil, removing the glycerine thus formed, and heating the residue to form new esters. For example, castor oil is heated with a mixture of sulphuric acid and a fat-splitting agent, until the mixture attains an acid value of 80 to 120. After settling, the lower layer containing sulphuric acid and glycerine is drawn off, and the upper layer containing fatty acids and glycerides is washed with water, and heated under reduced pressure to 482 DEG F., until esterification is complete. In the final stage the temperature may be raised to 575 DEG F. and, if necessary, a small amount of raw castor oil added to remove the traces of free acid remaining. During esterification, dehydrating agents, inert gases or catalysts such as tin or zinc may be added.
