Pentaerythritol tetraacetate

Pentaerythritol tetraacetate [597-71-7] M 304.3, m 78-79 . Crystd from hot water, then leached with cold water until the odour of acetic acid was no longer detectable. 

Pentaerythrityl bromide has been prepared by the action of phosphorus tribromide on pentaerythritol, - and of an acetic acid solution of hydrobromic acid on pentaerythritol tetraacetate. The iodide has been prepared by the action of red phosphorus and hydriodic acid on pentaerythritol and by treating the bromide with sodium iodide in acetone. ... 

Amylose triacetate prepared from butanol-precipitated starch may be plasticized with almost any of the common plasticizers which are applicable to the plasticization of cellulose triacetate. For example, some suitable plasticizers are dimethyl or diethyl tartrate, tributyl citrate, tributyl phosphate, tricresyl phosphate, polyethylene glycol, and pentaerythritol tetraacetate. Addition of only 10-20% plasticizer is sufficient to give amylose triacetate films a useful and lasting degree of...
