摘要

植物生物质转化的副产物是一种多组分树脂液体，包括不饱和和含氧物质。在25 ~ 90℃的盐酸和硫酸中作为低碳钢的缓蚀剂进行了试验。在低浓度的硫酸溶液和高浓度的盐酸溶液中，树脂表现出明显的保护作用。温度的升高导致添加剂的保护作用降低。确定了添加剂对腐蚀过程局部反应的影响。建立了抑制剂的作用机理。

WASTE OF BIOMASS CONVERSION AS INHIBITORS OF ACID CORROSION OF STEEL

By-products of plant biomass conversion are a multicomponent resinous liquid, which includes unsaturated and oxygen-containing substances. It was tested as corrosion inhibitor of low-carbon steel in hydrochloric and sulfuric acids at temperatures of 25-90° C. The resin shows noticeable protective effects at low concentrations in sulfuric acid solutions and when elevated in hydrochloric acid. The increase in temperature leads to a decrease in the protective effect of the additive. The influence of the additive on the partial reactions of the corrosion process is determined. The mechanism of inhibitor action is established.
