Abstract
1. A process for the production of urethanes by reacting a) urea or polyurets with b) primary amines and c) alcohols in the presence of catalysts at temperatures in the range from 120 to 350 degrees C, characterised in that the reaction is carried out in the presence of any esterification catalysts for carboxylic acids with the proviso that, in the production of di- and/or polyurethanes, the esterification catalysts are selected from the group comprising (i) inorganic or organic bases which are inert under the reaction conditions, (ii) Lewis acids, (iii) salts or complex compounds of transition metals, except for alcoholates of titanium, and (iv) lead naphthenate, acetyl acetonates of lead, aluminium or magnesium, dibutyl tin dilaurate, dibutyl tin diacetate, di-(2-ethylhexyl)-tin oxide, dioctyl tin oxide, tin salts of C1 -C20 -carboxylic acids and also acetates, chlorides, sulfates or octoates of divalent lead.
