as the production of fatty esters of furfuryl alcohol, the ester interchange method is indispensable. Fur- furyl alcohol resinifies in the presence of acids, but its esters may be produced by interchange using alkaline catalysts. The potential uses of the monohydric alkyl fatty esters are not yet fully realized, but there are many.
I. N a paper on industrial fat splitting, published recently in this Journal, L. Lascaray (3) raised several questions of both theoretical and practical importance. There is little doubt that, owing to his investigations (4) over the last 15 years, fat hydroly- sis by the autoclave and Twitchell processes has been recognized as an
This reaction was first reported by Twitchell in 1898.1 It is an industrial process for hydrolyzing fats and oils into fatty acids and glycerol, which is generally carried out in a loosely closed wooden, lead-lined or acid-resistant vat2 where the mixtures of fats or oils, 25–50% water, 0.5–2% sulfuric acid,3 and 0.75–1.25%
Commercial petroleum sulfonic acid reagents have been compared with Twitchell reagents, alkylarylsulfonic acids, and sulfoarylstearic acids as fat-splitting reagents in the hydrolysis of lard oil, tallow, cotton-seed oil, garbage grease, and inedible grease. The best reagents were made from commercial wetting agents of the

Convincing as his arguments are, he did not consider the kinetic order of the reaction, the study of which proved valuable in elucidating the related fat hydrolysis by acidification3. This omission was probably due to the existence of an induction period in the Twitchell process which tends to obscure its kinetics. Lewkowitsch
