Abstract: The present subject matter relates to a process for producing neopentyl glycol compacts, the process including at least the process steps of providing a fill of NPG flakes and compressing the fill in a mold to form a compact, wherein the compressing is performed at a pressure greater than or equal to 0.5 MPa and less than or equal to 7.5 MPa. Furthermore, the present subject matter relates to NPG compacts.

Abstract: The present invention relates to a process for the preparation of mixed polyol-carboxylic acid esters having a molecular weight of greater than or equal to 200 g/mol and less than or equal to 1000 g/mol, wherein a polyol is reacted in an at least two-step reaction with different monocarboxylic acids in the form of monocarboxylic acids or of monocarboxylic acid anhydrides, wherein the different monocarboxylic acids are reacted with the polyol in the order of their reactivity in the esterification reaction, starting with the lowest reactivity, wherein the monocarboxylic acids with the lower reactivity are reacted at least partly as monocarboxylic acid anhydride and the monocarboxylic acid with the highest reactivity is reacted thereafter as monocarboxylic acid with the polyol. Furthermore, the present invention relates to the use of the process for the preparation of mixed polyol esters.
