Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a novel method for producing acrolein or acrylic acid using ethyl alcohol as a raw material.SOLUTION: The method for producing acrolein or acrylic acid from ethyl alcohol comprises the following process: (1) (PP production step) a step of obtaining propylene from ethyl alcohol by using a catalyst; (2) (partial oxidation step) a step of obtaining acrolein or acrylic acid by partially oxidizing the propylene obtained in (1) in the presence of oxygen by using a partial oxidation catalyst; and (3) (separation step) a step of separating the acrolein or acrylic acid obtained in the partial oxidation step. 【課題】本発明は、エチルアルコールを原料に新規なアクロレイン又はアクリル酸の製造方法を提供するものである。【解決手段】本発明は、以下の手順によることを特徴とするエチルアルコールからアクリル酸又はアクロレインの製造方法である。（１）触媒を用いてエチルアルコールからプロピレンを得る工程（ＰＰ製造工程）。（２）部分酸化触媒を用いて酸素存在下に（１）で得られたプロピレンを部分酸化しアクロレイン又はアクリル酸を得る工程（部分酸化工程）。（３）当該部分酸化工程で得られたアクロレイン又はアクリル酸を分離する工程（分離工程）。【選択図】図１
