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.
