Aim\ Enanthal diethyl acetal is prepared with heptaldehyde and triethyl orthoformate as raw materials. Methods\ Optimal reaction conditions were drawn from orthogonal experiments. Results\ The best technology was concluded to yield over 95% of enanthal diethyl acetal. Conclusions\ By contrast, with sodium hydrogen sulfate as catalyst, simple later disposal and higher yield are the major advantages.
