Glyceryl triacetate

Heptafluoro-2-iodopropane [677-69-0] M 295.9, b 41 . Purified by gas chromatography on a triacetin (glyceryl triacetate) column, followed by bulb-to-bulb distn at low temperature. Stored over Cu powder to stabilise it. 

Glyceryl acetate, which is an artificial ester commonly used in the adulteration of bergamot oil, is detected fairly easily on account of its high solubility in dilute alcohol. The test is carried out as follows Ten c.c. of bergamot oil and 20 c.c. of 5 per cent, alcohol are well shaken in separating funnel, and after the solutions have separated and become clear the watery solution is run off and filtered. Ten c.c. of the filtrate are exactly neutralised with deci-normal alkali, and then 5 c.c. of seminormal alkali run in, and the whole saponified under a reflux condenser for one hour. In the case of pure bergamot oil 0 1 or at most 0 2 c.c. of semi-normal alkali will have been used up by the saponification, whilst each 1 per cent, of glyceryl triacetate present in the oil will be represented by practically 0 5 c.c. of semi-normal alkali.

Irradiation of /3- and -y-ketoalkenes may produce some highly strained and unusual polycyclic oxetanes. For example, from 7,8-dihydro-/3-ionone (62) at 25 °C in pentane solution there was obtained a 70% yield of (63), while in glyceryl triacetate solution at 60 °C a 10% yield of (64) was obtained (as well as other products, of course). This is an example of the possibilities for rather complex cycloadditions to occur, in the course of generating an oxetane structure (80HCA154). 

Polyvinyl acetate phthalate (PYAP) dissolves at pH higher than 5 and is soluble in ethanol. Plasticizers that are used with PVAP include triethyl citrate, glyceryl triacetate, and acetyltriethyl citrate.
