This study mainly aims to correlate the effect of high-pressure CO₂−Water slug flow formed by microfluidic mixing on the extraction of phenolic compounds (gallic acid, protocetechuic acid, cafeic acid, syringic acid, ferulic acid, and benzoic acid) from its multi-component aqueous solutions. Both slug flow observation and extraction performances were experimentally conducted at different CO₂ flow rates (100–650) ml min⁻¹, temperatures (25–60) ^oC, and pressures (8.0–20.0) MPa. The slug flow patterns are affected by all CO₂ flow rates, temperatures, and pressures. The slug flow patterns have a strong correlation with the extraction efficiencies of phenolic compounds from the aqueous solutions. Using slug flow process, benzoic acid can be completely purified from the multi-component aqueous solutions by supercritical CO₂ extraction.

这项研究的主要目的是关联微流体混合形成的高压CO _2-水团流对其从中提取酚类化合物（没食子酸，原tech酸，咖啡酸，丁香酸，阿魏酸和苯甲酸）的影响。多组分水溶液。在不同的CO ₂流速（100–650）ml min ^-1，温度（25–60）^o C和压力（8.0–20.0）MPa的条件下，均进行了塞流观测和提取性能试验。团状流型受所有CO ₂影响流速，温度和压力。团状流型与从水溶液中提取酚类化合物的效率有很强的相关性。使用团流法，可以通过超临界CO ₂萃取从多组分水溶液中完全纯化出苯甲酸。
