Abstract: A photopolymerizable recording composition which comprises a mixture, containing a photoinitiator, of (a) a photopolymerizable olefinically unsaturated monomer and (b) an organic polymeric binder, wherein the photoinitiator is an acylphosphine oxide compound of the formula R1R2PO-CO-R3, where R1 and R2 are certain organic radicals and R3 is tert.-alkyl or a cyclic radical with two substituents in the ortho-position to the carbonyl group. The recording compositions have a high reactivity when irradiated with UV light and are used in particular for the preparation of printing plates, relief plates and photo-resists.

Abstract: Purification of 2,3,5-trimethyl-p-benzoquinone (TMQ) or isolation of TMQ from a mixture, by crystallization. An Independent claim is included for preparation of TMQ by catalytic oxidation of TMP with oxygen to give a mixture containing TMQ as well as TMP and/or at least 1 of solvent, catalyst-residue, by-product and intermediate, followed by work-up as above.

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.

Abstract: A growth-promoting additive for feeds consists of a commercial growth promoter as well as an aminoreductone of the formula I where R1, R2 and R3 are each hydrogen, methyl or ethyl and R4 is an unsubstituted or substituted C1-C20-alkyl or alkenyl radical or a radical of an aminoacid.
