摘要： Disclosed is a class of poly(aminoaromatic) compounds (I) obtained by capping polymeric polyols or polythiols with aromatic amine groups wherein the latter groups are linked by --O--or --S--to the polyol (polythiol) residues. Also disclosed are the precursor poly(nitroaromatic) compounds (II) from which the compounds (I) are derived.The polyamines are characterized by amine reactivities in respect of isocyanate polyaddition reactions which allows for polymer reaction rates that are intermediate of prior art related polyamine compounds.Accordingly, the compounds (I) find their prime utility in the formation of synthetic resins containing polyurea linkages.

摘要： An improved process for the nitration of aromatic hydrocarbons is described. The aromatic hydrocarbon (benzene, toluene of particular interest) is reacted with gaseous nitrogen dioxide in the presence of a catalytic amount of sulfuric acid and in the absence of oxygen. The process is highly selective and avoids the formation of undesired by-products. The acid employed as catalyst can be recovered and recycled after removal of water of condensation liberated in the reaction.

摘要： Disclosed is an improved process for the preparation of carbamates by heating an organic carbonate and an aromatic urea or polyurea in the presence of aluminum as catalyst and a promoter comprising a combination of iodine and a mercury salt.High reaction temperatures are avoided by the process and conversions to carbamate products are high. Additionally, the process is economically attractive because even the common aluminum foil can be used as the catalyst.The products prepared by the process can be used in the production of insecticides, and, particularly, as intermediates in the preparation of organic mono- and polyisocyanates.
