摘要:

在工业级过氧化氢生产过程中,通过合理选择管道设备材质、高质量钝化、使用精密过滤等方式,降低铁离子含量;通过选用高效溶剂、适当降低再生和反应温度、汽提或者净化,降低总有机碳(TOC)含量;通过提高系统洁净度,进而降低稳定用磷酸量,选择无磷或者低磷的稳定剂,降低磷酸根离子含量;通过温度、pH、杂质三要素的控制,提高产品稳定度,并根据下游产品选用稳定剂种类;控制过氧化氢pH不得高于6,建议保持在2~3,增加安全性和提高质量;对下游不同产品己内酰胺、四溴双酚A等的敏感元素进行控制,满足生产需要。通过上述控制措施,可以让工业级过氧化氢达到下游化工制造质量标准,不再新建净化提纯装置,降低了成本,提高了安全性。

Abstract:

In the industrial grade hydrogen peroxide production process,the iron ion content was reduced through reasonable selection of pipeline equipment materials,high-quality passivation,and the use of precision filtration.The total organic carbon TOC content was reduce by selecting efficient solvents,appropriately reducing the temperature of regeneration and reaction,stripping or purification.The content of phosphate ions was reduced by improving the cleanliness of the system,reducing the amount of stable phosphoric acid used and using stabilizers with no or low phosphorus.By controlling temperature,pH,and impurities,product stability could be improved,and stabilizer types could be selected based on downstream products.The pH of hydrogen peroxide was controlled to not exceed 6,and it was recommended to maintain it at 2~3 to increase safety and improve quality.The sensitive elements of different downstream products such as caprolactam and tetrabromobisphenol A was controlled to meet production needs.Through the above control measures,industrial grade hydrogen peroxide could meet downstream chemical manufacturing quality standards,without the need for new purification and purification devices,reducing costs and increasing safety.

Key words: hydrogen peroxide, iron ions, TOC, pH, quality improvement
