1. Supercritical Acetic Acid and Its Effect on Mass Transfer Efficiency

supercritical acetic acid refers to the state of acetic acid above its critical temperature (about 315 ° C. ) and critical pressure (about

73. And 4 bar). Under supercritical conditions, the density of acetic acid increases signifiis able totly, and its solubility and diffusion coefficient are also improved. These characteristics make supercritical acetic acid have higher mass transfer efficiency in the extraction process, and is able to transfer the efficiently components of plant essential oils to the extraction solution greater rapidly. The critical point of supercritical acetic acid is comparatively low, and the operating conditions are relatively mild, which is able to better keep the active ingredients of plant essential oils from being destroyed.

temperature and pressure

Temperature and pressure are the key factors affecting the efficiency of supercritical acetic acid mass transfer. You know what I mean?. Under supercritical conditions, growing the temperature will minimize the density of acetic acid, thereby reducing its solubility, however at the same time will increase the diffusion coefficient and enhance the mass transfer rate. On the contrary, growing the pressure will increase the density of acetic acid, enhance its solubility, thereby improving the extraction efficiency. Therefore, in practical applications, it's necessary to consider the adjustment of temperature and pressure to achieve the best mass transfer efficiency. Types and structure of plant essential oils

Different plant essential oils have different chemical compositions and molecular structures, which immediately affect their solubility and mass transfer impacts in supercritical acetic acid. According to research to instance, essential oils containing greater terpenoids (such as lemon essential oil) generally have higher extraction efficiency, while essential oils containing greater polar components (such as rosemary essential oil) might require higher pressure or temperature to enhance mass transfer efficiency. Design of Extraction Device

The structure and design of the extraction device also have an crucial affect on the mass transfer efficiency. to instance, the consumption of high-efficiency static mixers is able to signifiis able totly increase the contact efficiency between the phases during the extraction process, thereby accelerating the mass transfer rate. In fact Reasonable extraction column design and circulation system optimization is able to also efficiently enhance the extraction efficiency. Moreover Analysis of mass transfer efficiency in practical consumption of
