word of the day: monotectic

The word of the day is monotectic:

The reversible transition, on cooling, of a liquid to a mixture of a second
liquid and a solid.  (IUPAC Compendium on Chemical Terminology)

"An equimolar mixture of dilauroyl phosphatidylcholine and distearoyl phosphatidylcholine, which shows a monotectic behaviour, is hydrolysed at all temperatures."
