## Abstract **BACKGROUND:** Propylene glycol ether is expected to be a safe substitute for toxic ethylene glycol ether usually used in industry owing to its negligible toxicity. Although catalysis of solid acids or bases for the synthesis of the ether can avoid separation of catalysts, liquid waste
