  • Method for separating polyisoprene and other apolar valuable substances from vegetable feedstock
    Patent number: 12583953
    Abstract: The present invention relates to a method for separating polyisoprene and/or other apolar valuable substances from vegetable feedstock, with a first pretreatment (100) of the vegetable feedstock; a percussive, cutting and/or rubbing mechanical processing (102) of the vegetable feedstock after the pretreatment in a wet phase, during which the polyisoprene and/or other apolar valuable substances contained in the processed raw plant materials are extracted from the vegetable feedstock; and after the mechanical processing (102), a separation (104) of the polyisoprene and/or the other apolar valuable substances from the wet phase. The invention proposes that, before or during the mechanical processing (102) in the wet phase, an adsorber material (106) be added to the ground product mixture to create a method which makes it possible to obtain polyisoprene and other apolar valuable substances from plants having a low rubber content in a technically simpler manner.

  • Method for Separating Polyisoprene and Other Apolar Valuable Substances from Vegetable Feedstock
    Publication number: 20230069783
    Abstract: The present invention relates to a method for separating poly-isoprene and/or other apolar valuable substances from vegetable feedstock, with a first pretreatment (100) of the vegetable feedstock; a percussive, cutting and/or rubbing mechanical processing (102) of the vegetable feedstock after the pre-treatment in a wet phase, during which the polyisoprene and/or other apolar valuable substances contained in the processed raw plant materials are extracted from the vegetable feedstock; and after the mechanical processing (102), a separation (104) of the polyisoprene and/or the other apolar valuable substances from the wet phase. The invention proposes that, before or during the mechanical processing (102) in the wet phase, an adsorber material (106) be added to the ground product mixture to create a method which makes it possible to obtain polyisoprene and other apolar valuable substances from plants having a low rubber content in a technically simpler manner.
