Abstract: In parent patent, the continuous prodn. of N-alkylarylamines (I) comprises gas-phase reaction of arylamines (II) with alcohols (III) and/or dialkyl ethers (IV) at 180-450 degrees C in presence of carriers contg. oxyacids of P. The catalyst used is silica of internal surface 50-500 m2/g and H3PO4 content 0.1-20 wt.% and during the reaction H3PO4 and/or alkyl phosphates are continuously supplied to the catalyst. In this addition (II) and (III) or (IV) are introduced as gases at a temp. equal to or greater than the reaction temp. By using the reactants to heat the catalyst, surface coking is reduced.

Abstract: Prepn. of mono- or poly-, symmetrical or asymmetrical tert-amines comprises reacting a prim. or sec. amine R1-NH-R2 (where R1 and R2 are each H, alkyl or cycloalkyl gps., opt. substd. by inert substs. which, in turn, may carry amino gps. -NHR1) with mono- or di-hydric prim. or sec. - alcohols. The reaction is catalysed by a hydrogenation/dehydrogenation catalyst, opt. in the presence of H2, and the amine is fed into the liq. reaction mixt. contg. the mixt. of alcohol required for the reaction and the proportion of water formed in the reaction is eliminated. High yields of tert-amines are obtd. with low amts. of prim- and sec-amine contamination. Since the alcohol reactant is completely consumed the sepn. of alcohol from tert-amine, which is usually difficult and energy-consuming, is avoided.

Abstract: N-formyl morpholine is prepared by reacting methyl formate and morpholine in a stoichiometric ratio, these reactants being a admixed and after 7-10 hrs at 85-95 degrees C, passed to a rapid vaporisation device where, at a surface temp. of 135-145 degrees C and residence time of 0.5-5 min, the mixture is freed from MeOH. The yield of N-formyl morpholine is almost quantitive.
