    Noob so please play kind

    I'm looking to solvent extract an active agrochemical from a formulation which contains 40-45% of a C8-C13 hydrocarbon.
    Water is not a viable choice.
    There will be other components present

    A fatty alcoholpolyglycol ether (34-38%)
    Propylene carbonate (4-7%)
    Active (7-12%)


    Has anyone had success on solvent extraction on hydrocarbons?

    Had wondered about trying to distill the HC under vac to leave the other components then extracting the active in solvent.

    Or can suggest a viable way to extract my target active from this mixture.

    Myxi

    It might help if you tell us what the "active" is...

    Off the top of my head distillation under vacuum is probably the way forward but that depends on what the boiling point of "active" is (ideally it should be higher than the other components for distillation to work. An alternative, if you can find a solvent that "active" dissolves in but the other components don't and the solvenet is immiscible with the other components you could just use a separating funnel.

    Have remade this in the chemistry forum where I actually thought I had put it already, apologies for doing twice.

    Active degrades at/around 200°C, but do not want to get anywhere near that temperature.
    Really would like suggestions on a solvent that is immiscible to HC and try to solvent extract into, clean and recrystallize.

    Again, without knowing what "active" is I can't help you!
