摘要： 1330104 Aromatic nitrohalogens BAYER AG 11 Jan 1971 [15 Jan 1970] 1167/71 Heading C2C Aromatic halogen compounds containing at least two nitro groups are prepared by reacting an aromatic hydroxy compound containing up to 14 carbon atoms in the aromatic portion and having one or two hydroxy groups each activated by at least two nitro groups in the particular ortho-positions to the OH group, or in the ortho- and para-positions, with at least the stoichiometrically necessary quantity of an acid chloride or bromide in the presence of an acylated secondary amine as catalyst at a temperature in the range 50‹ to 200‹ C. Preferred catalysts are dimethylformamide and tetramethyl urea in an amount of from 1 to 10% by weight of the hydroxy compound and preferred acid halides are phosgene, acetyl chloride and thionyl chloride. The process may be carried out in an inert organic solvent.

摘要： Novel aromatic diamines having the general formula WHEREIN N IS AN INTEGER OF FROM 2 TO 8, X is sulfur or oxygen, and R is an n-valent hydrocarbon radical which may be interrupted by O or S atoms and which is obtained by removing OH or SH groups from a polyol or polythiol having a molecular weight of less than 600, are prepared by reacting a compound having the formula (HX)nR where X, n and R are as defined above with about n-equivalents of an isatoic acid anhydride in the presence of a strong base. The aromatic diamines of the invention are particularly useful as the active hydrogen containing component for reaction with polyisocyanates in the preparation of synthetic resins by the isocyanate-polyaddition process.
