PROCESS FOR THE SIMULTANEOUS PRODUCTION OF DIFFERENT MIXTURES OF DIISOCYANATE ISOMERS OF THE DIPHENYLMETHANE SERIES

Process for the simultaneous and continuous production of two different mixtures of predominantly 4,4'-MDI and 2,4'-MDI in a single-step suspension melt crystallisation process whereby a mixed diisocyanate feed stream [MIx] is used to produce simultaneously two mixed diisocyanate streams [...

description Process for the simultaneous and continuous production of two different mixtures of predominantly 4,4'-MDI and 2,4'-MDI in a single-step suspension melt crystallisation process whereby a mixed diisocyanate feed stream [MIx] is used to produce simultaneously two mixed diisocyanate streams [MIy and MIz] wherein x is 8 to 20, y is 1 to 3 and z is 20 to 40 where x, y and z are percentages by weight of the 4,4'-diphenylmethane diisocyanate isomer contained in the diphenylmethane diisocyanate isomer mixture.
