Ethoxylated monoalkanolamides

With monoalkanolamide or ethoxylated monoalkanolamide sulphate. Acid hydrolysis (section 2.4.4). Then any of the following. 

Alkali. Contrary to the general belief, dialkanolamides are readily saponified by boiling with 0.5 M ethanolic alkali, but monoalkanolamides are little affected by this treatment. Both types are hydrolysed by boiling for 6h with IM potassium hydroxide in ethylene glycol, which boils at 197°C. They are converted to soap and the corresponding alkanolamine. Ethoxylated derivatives behave similarly.
