    Abstract: Triphenylphosphine (TPP) is obtained from a solution of a triphenylphosphine-aluminium chloride complex in chlorobenzene by decomplexation, hydrolysis and extraction by means of water and subsequent separation of the liquid/liquid dispersion - consisting of a chlorobenzene phase containing TPP and a water phase containing Al and Cl compounds - into a chlorobenzene phase containing TPP and into a TPP-free water phase containing Al and Cl compounds, characterised by - dispersing water in the chlorobenzene phase in a 1st mixing device in the ratio of 0.6 to 0.95 kg of water per kg of chlorobenzene solution such that as a result of the hydrolysis a temperature in the range from 60 to 90 DEG C is established, residence times of 5 to 30 minutes and energy densities of 2 to 10 kW/m being kept to during dispersing, - redispersing in a 2nd mixing device, residence times of 5 to 60 minutes and energy densities of 0.05 to 0.5 kW/m being kept to, and separating into the specifically heavier chlorobenzene phase containing TPP and into the specifically lighter TPP-free water phase containing Al and Cl compounds by means of a phase-separating vessel.

    Abstract: A process for removing unwanted odours from mixtures of fatty acid esters which, besides other components, contain the esters of highly unsaturated fatty acids, especially of highly unsaturated omega -3-fatty acids, such as eicosapentaenoic acid or docosahexaenoic acid, is characterised in that the mixture of fatty acid esters is treated with complex hydrides, in particular with sodium borohydride solution. The process is particularly suitable for removing unwanted odours from mixtures of fatty acid esters which have been obtained from fish oil, for example from fish oil by transesterification with alkanols with 1 to 3 C atoms.
