    Abstract: The invention is a process for epoxidizing an olefin with hydrogen and oxygen in a solvent comprising acetonitrile in the presence of an quinone-acid salt and a catalyst comprising a titanium zeolite and a noble metal. The process results in higher productivity and improved selectivity to propylene oxide from hydrogen and oxygen, as compared to processes that use only a quinone.

    Abstract: A process for making propylene oxide from propylene is disclosed. The process comprises reacting propylene, oxygen, and hydrogen in the presence of a catalyst and a solvent to produce a reaction mixture comprising propylene oxide. Separation of propylene, oxygen, hydrogen, and propylene oxide from the reaction mixture results in a residual mixture comprising methanol. A portion of the residual mixture is recycled to the reaction. A portion of the residual mixture is distilled to generate a distilled methanol stream, which is recycled to the reaction.

    Abstract: A process for making propylene oxide from propylene is disclosed. The process comprises reacting propylene, oxygen, and hydrogen in the presence of a catalyst, a solvent, and a buffer to produce a reaction mixture comprising propylene oxide. Separation of light components from the reaction mixture gives a heavy residue comprising the buffer. The buffer is precipitated from the heavy residue by a precipitating agent.
