Abstract: Organic condensation reactions are carried out at elevated temperatures by a method in which the starting material or materials are fed in, in gaseous form, at the bottom of a reactor charged with a mineral oil having a boiling point of not less than 150 DEG C., or are fed in, in liquid form, at the bottom of the reactor, and the mineral oil is kept at a temperature which is no lower than the boiling points, of the starting materials introduced as liquids, which correspond to the partial pressures, of the said starting materials, resulting at the bottom of the reactor, and the product is taken off, in gaseous form, at the top of the reactor.

Abstract: 2-Imidazolines are prepared by reacting N,N'-diformyl-1,2-diamines in the gas phase at 200 DEG -350 DEG C., in the presence of certain amounts of an inert gas, over zinc oxide of a particular structure or over a mixture of this zinc oxide and aluminum oxide, as the catalyst. The 2-imidazolines obtainable by the process according to the invention are valuable starting materials for the preparation of dyes, crop protection agents and drugs.

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: 1466914 N-Alkylarylamines BASF AG 12 July 1974 [14 July 1973] 30910/74 Heading C2C In a process for the continuous production of a N-alkylarylamine by the reaction of an arylamine with an alkanol and/or a dialkyl ether in the gas phase at 180 to 450 C. in the presence of a carrier substance containing an oxyacid of phosphorus, there is used as the catalyst a silicic acid having an internal surface area of 50 to 500 sq. metres per gm. and having a phosphoric acid content of from 0À1 to 20% by wt., and phosphoric acid and/or an alkyl phosphate is continuously supplied to the catalyst during the reaction. The arylamine starting material preferably has the formula wherein R 1 is hydrogen or C 1 to C 4 alkyl; R 2 is hydrogen; R 3 is hydrogen, cyano, nitro, C 1 to C 4 alkyl or alkoxy or a radical of the formula wherein R 4 is C 1 to C 3 alkylene or alkylidene; R 5 is hydrogen or (when n=1) C 1 to C 4 alkyl, and R 6 is hydrogen; and n is 1 or 2.
