Abstract: The invention relates to a process for removing salts from an alkanolic reaction mixture which is obtained in the preparation of alkoxycarbonylaminotriazines and comprises at least one alkoxycarbonylaminotriazine, at least one cyclic and/or acyclic carbonic ester, at least one C 1 -C 13 -alkanol which optionally comprises one or two oxygen atoms as ether bonds and is optionally substituted by C 1 -C 4 -alkyl and/or hydroxyl, and also at least one alkali metal alkoxide or alkaline earth metal alkoxide, with or without melamine and with or without catalyst, in which salts are removed from the reaction mixture by ion exchange over a cation exchanger and/or anion exchanger.

Abstract: Aqueous melamine resin mixture (I) comprises a resin content (50-70 wt.% based on (I)) comprising polyvalent alcohols (a) (1-10 wt.%), caprolactam (b) (0-8 wt.%) and 2-(2-phenoxy-ethoxy)-ethanol (c) (0.5-10 wt.%) and/or polyethylene glycol (d) with an average molecular weight of 200-1500, respectively based on (I); where the molar ratio of melamine and formaldehyde present in the resin is 1:3-1:1. Independent claims are also included for the preparation of (I) comprising converting (I) in a pH of 8-10 at 60-160[deg]C; and a composite material obtained by thermal treatment of (I) with a support material.

Abstract: MDI is prepared by a process comprising the following steps: A) reaction of aniline and formaldehyde in the presence of an acid to give methylene(diphenyldiamines) and polymethylenepolyphenylenepolyamines, the molar ratio of acid to amine being not more than 0.2, B) reaction of the mixture obtained in step A) with phosgene to give methylene(diphenyl diisocyanates) and polymethylenepolyphenylene polyisocyanates, C) separation of the mixture obtained in step B) into monomeric MDI and polymeric MDI and D) separation of the monomeric MDI obtained in step C) by isolating 2,4'-MDI.
