Abstract
The report presents experimental results, which can be considered as the reference for innovative generations of supercritical fluids (SCF), liquid–liquid (LL), and liquid (L) extraction technologies. They are related to implementations of Critical Phenomena Physics, for such applications not considered so far. For the gas–liquid critical point, the shift SuperCritical Fluids (SCF) ⇒ SubCritical Fluids, due to the additional exogenic impact of ultrasounds, is indicated. For LL technology, the possibility of increasing process effectiveness when operating near the critical consolute under pressure is indicated. Finally, the discovery of long-range precritical-type changes of dielectric constant in linseed oil, standing even 50 K above the melting temperature, is presented. It suggests that extraction processes linking ‘SCF’ and ‘L’ technologies features and exploring the natural carrier, such as linseed oil, are possible. The report recalls the fundamental base for extraction processes via Kirkwood and Noyes–Whitney relations and presents their implementations to ‘critical conditions,’ including pressure.

新一代气-液、液-液和液 (LE) 萃取技术的临界相关基础
摘要
该报告介绍了实验结果，可作为创新代超临界流体 (SCF)、液-液 (LL) 和液 (L) 萃取技术的参考。它们与关键现象物理学的实现有关, 对于迄今为止未考虑的此类应用程序。对于气液临界点，由于超声波的额外外生影响，指示了超临界流体 (SCF) ⇒ 亚临界流体的转变。对于 LL 技术，指出了在压力下在临界浓度附近操作时提高过程效率的可能性。最后，介绍了亚麻籽油中介电常数的长程预临界型变化的发现，甚至高于熔点 50 K。这表明将“SCF”和“L”技术特征联系起来并探索亚麻籽油等天然载体的提取工艺是可能的。该报告通过 Kirkwood 和 Noyes-Whitney 关系回顾了提取过程的基本基础，并提出了它们在“临界条件”（包括压力）下的实施。
