Acetone recovery and purification

Methods and systems for preparing acetone from cumene hydroperoxide (CHP) are disclosed. The disclosed methods involve cleaving CHP to form a cleavage product stream. In some embodiments, the cleavage product stream is separated into an overhead stream and a bottoms stream. The bottoms stream is neutralized, washed and then treated in a crude acetone column to provide a crude acetone stream. The overhead stream of the cleavage product is flashed forward in the process, bypassing the neutralization, washing, and crude acetone column and is then combined with the crude acetone stream. The combined acetone streams are provided to an acetone product column. According to some embodiments, the acetone product column comprises a side draw for obtaining a recycle acetone stream, which is recycled to the cleavage reactor(s). The recycle acetone side draw may be located lower on the acetone product column than the point from which product acetone is obtained. The disclosed methods increase the efficiency of the process.

SOLIDIFICATION OR CRYSTALLISATION METHOD

A solidification or crystallization method is disclosed, which includes providing at least a first organic compound and at least one volatile co-former organic compound. A mixture of at least the first organic compound and the co-former organic compound is formed, wherein either the first organic compound or the volatile co-former organic compound includes a hydrogen acceptor moiety and the other includes a hydrogen donor moiety, thereby allowing the formation of hydrogen bonds between the first organic compound and the volatile co-former organic compound. The mixture is allowed to stand for sufficient time for the mixture to liquify at a temperature below that of the melting points of the components, thereby forming a liquid mixture. The volatile co-former organic compound is allowed to evaporate, thereby resulting in crystallization of at least the first organic compound. The method can be a co-crystallization method if there are two organic compounds.
