The invention discloses a method for catalyzed synthesis of a 1,3-butadiyne compound from carboxymethylcellulose/nano-copper in supercritical carbon dioxide. The method includes sequentially adding end-group alkyne compounds, carboxymethylcellulose/nano-copper and tetrahydrofuran into a high-pressure reactor, sequentially feeding O2 and CO2 into the high-pressure reactor to reach a set pressure, heating to 25-66 DEG C to react by oil bath under electromagnetic stirring, cooling the high-pressure reactor after reaction, releasing gas, desorbing by diethyl ether, filtering to remove undissolved substances, and subjecting filtrate to evaporation and concentration so as to obtain the target product, namely the 1,3-butadiyne compound. The method for catalyzed synthesis of the 1,3-butadiyne compound from the carboxymethylcellulose/nano-copper in the supercritical carbon dioxide is cheap and easily available to a catalysis system, wide in substrate application range and high in total yield.
