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.
该报告介绍了实验结果，这些结果可被视为创新一代超临界流体（SCF）、液-液（LL）和液（L）萃取技术的参考。这些结果与临界现象物理学的应用有关，而这些应用迄今为止尚未被考虑。对于气-液临界点，由于超声的外加影响，超临界流体（SCF） ⇒ 亚临界流体的转变被指出。对于 LL 技术，在压力下接近临界共溶点操作时，提高过程效率的可能性被指出。最后，报告中还介绍了亚麻籽油中介电常数在远距预临界型变化的发现，即使在熔点以上 50K 也能保持。这表明，通过柯克伍德和诺伊斯-惠特尼关系进行的萃取过程以及探索天然载体（如亚麻籽油）的萃取过程是可能的。该报告回顾了通过 Kirkwood 和 Noyes-Whitney 关系进行萃取过程的基本基础，并将它们的应用扩展到包括压力在内的“临界条件”。
