A deicing agent from renewable resources is necessary to overcome the disadvantages of traditional deicing agents. In this study, biomass autohydrolyzate was evaluated for its applicability as corrosion inhibiting deicing agents. Autohydrolyzates treated with alkali showed significant freezing point depression and corrosion inhibiting effects on mild steel. Freezing points for autohydrolyzate treated with 2% (w/w) sodium hydroxide were depressed at -64.0 °C (56% solids content), and its maximum corrosion inhibiting efficiency was 61.5%. This material was found to be more effective than a tested commercial deicing agent. This strong performance is considered due to the xylooligosaccharides being degraded to various sugar acid compounds under alkaline treatment conditions, providing the mixture with solutes with corrosion inhibition potency. In conclusion, alkaline treated autohydrolyzate could replace traditional deicing agents based on superior performance and a sustainable production scheme.
需要一种来自可再生资源的除冰剂来克服传统除冰剂的缺点。在本研究中，对生物质自水解产物作为缓蚀除冰剂的适用性进行了评估。经碱处理的自水解产物对低碳钢表现出显著的冰点降低和缓蚀作用。用2%（w/w）氢氧化钠处理的自水解产物在-64.0℃（固体含量56%）时冰点降低，其最大缓蚀效率为61.5%。发现这种材料比一种测试的商用除冰剂更有效。这种优异的性能被认为是由于木寡糖在碱性处理条件下被降解为各种糖酸化合物，为混合物提供了具有缓蚀能力的溶质。总之，基于优异的性能和可持续的生产方案，经碱处理的自水解产物可以替代传统除冰剂。
