【摘要】 采用循环伏安法分别测定了脂肪族正链醇和水溶性醛在 Na₂SO₄,H₂SO₄和 NaOH 溶液中的半波电势 E_1/2,结果表明,E_1/2与电极特性和溶液酸度有关,与正链醇的链长基本无关.使用铂电极,在H₂SO₄溶液中,E_1/2,醇=0.60～0.66,0.90～0.97 V（vs SCE）,E（1/2,醛）=0.85～0.95 V（vs SCE）.更多还原

【Abstract】 The half-wave potentials E_1/2 for normal aliphatie alcohols and hydrate aldehydes are studied by the methods of cyclic voltammogram in Na₂SO₄,H₂SO₄ and NaOH solution.The effect of pH and electrode characteristics on E_1/2 is observed,but that of chain length is not.At platinum electrode,in H₂SO₄ solution,E_1/2（alcohol）=0.60～0.66,0.90～ 0.97V（vs SCE）,E_1/2（aldehyde）=0.85～0.95V（vs SCE）.更多还原
