Abstract:
A process for manufacturing crystals of 1,4:3,6-dianhydrohexitols, by manufacturing a solution of an internal dehydration product of at least one hexitol, distilling the solution, crystallizing, and wherein the crystallization mother liquors undergo a step of evaporative crystallization. Unlike the prior art processes that seek to recycle the crystallization mother liquors, evaporative crystallization economically and efficiently replaces the succession of steps consisting of at least one concentration, then at least one step of purification by distillation, chromatography, or crystallization.

Claim (Index 3):
The process as claimed in  claim 1 , wherein a part of the mother liquor stream (1 bis) resulting from the draining step d) undergoes an evaporative crystallization step e), from 50% to 99.9% by weight of the stream undergoing the evaporative crystallization step, and from 0.1% to 50% by weight of the stream being reintroduced into the distillate at the crystallization step c).
