1 产品用途在日用化学领域大量用于生产香兰素等芳香醛;在农药领域用于生产植物生长调节剂尿囊素、除草剂草甘膦、禾草克、哒草特和杀虫剂喹硫磷;在医药工业用于生产抗高血压病药物阿替洛尔和广谱抗生素羟氨苄青霉素;在水处理中用于生产高效水处理剂羟基膦羧酸等。 2 技术特点乙醛酸的生产方法有草酸电解还原法、乙二醛硝酸氧化法和顺酐臭氧化法。乙二醛硝酸氧化法生产工艺简单,投资少,有明显的经济效益,适用于无机酸不需要分离、可直接应用的小规模生产。装置建在原料乙二醛生产厂或具
1 The product uses in the field of daily-use chemistry for the production of aromatic aldehydes such as vanillin; in the field of pesticides for the production of allantoin plant growth regulators, herbicides glyphosate, valerianke, valerian and pesticides Quetion; in the pharmaceutical industry for the production of anti-hypertensive drugs atenolol and broad-spectrum antibiotics amoxycillin; used in water treatment for the production of high-efficiency water treatment agent hydroxy phosphonate carboxylic acid. 2 Technical characteristics Glyoxylic acid production methods are oxalic acid electrolysis reduction method, glyoxal nitrate oxidation method and maleic anhydride ozonation method. The glyoxal nitric acid oxidation process has a simple production process, low investment, and obvious economic benefits. It is suitable for small-scale production where inorganic acids do not need to be separated and can be directly applied. The device is built at the raw material glyoxal production plant or
