| 摘 要： | 本文报导了一项稳定糠醛产品低含水量的工业性试验。研究表明提高精制系统的气密性是降低并稳定成品合格水分的基本措施;采用二槽阶梯式粗醛高位槽可以提高脱水塔的操作稳定性,从而提高成品水分含量的稳定性。山西省寿阳县有机化工厂采用上述方法生产的糠醛的含水率长期持续稳定,其位为0.01～0.03％,符合《工业糠醛》国家标准GB1926-80。对比研究结果表明,成品露天贮放,特别是在夏秋多雨季节,是造成贮放产品水分骤升的主要原因,从而说明建库贮放十分必要。

| Abstract: | It has been proven that improving the airtightness of the distillation system used for commercial furfural production is the effective measure to achieve and stabilize the low moisture content of the final products. Installation of two crude furfural supply tanks arranged on stairs is beneficial for operational steadiness of the dehydrating column.Since adoptation of these measures, the Organic Chemical Plant in Shouyang County, Shanxi Province has insisted on producing superior grade furfural with moisture content ranging from 0.01-0.03% which meets the requirements of the Chinese National Standard of commercial furfural GB 1926-80. |
