    Abstract: The invention relates to a method for producing MD1, comprising the following steps: A) aniline and formaldehyde are made to react in the presence of an acid to form methylene(diphenyldiamene) and polymethylene polyphenylene polyamine, the mol ratio of acid to amine being a maximum of 0.2; b) the mixture obtained in step A) is reacted with phosgene to form methylene (diphenyldiisocyanate) and polymethylene polyphenylene polyisocyanate; C) the mixture obtained in step B) is separated into monomer MDI and polymer MDI; and D) the monomer MDI obtained in step C) is separated from 2,4'- MDI.

    Abstract: Highly functional aromatic polyisocyanates are prepared by reacting aromatic polyisocyanates, if required as a mixture with further mono- and/or polyisocyanates, with addition of catalytic acidic substances and water, by a process wherein the aromatic polyisocyanates used comprise at least one tolylene diisocyanate and the catalytic acidic substance used is at least one alkyl and/or aralkyl phosphate, and the process is carried out in such a way that the water is added with a temperature/time gradient increase from 5 to 60°/hour and until an isocyanate modification of the starting NCO terminal groups from 1 to 80% is established. The highly functional aromatic polyisocyanates prepared by this process are used for the preparation of polyurethane foams, in particular flexible polyurethane foams.
