    摘要: A process for preparing triethylenediamine by passing an amine compound over a catalyst at elevated temperature to afford a reaction product containing triethylenediamine and piperazine, the amine compound having, in the molecule, a moiety represented by the following general formula ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently a hydrogen atom or an alkyl group having 1 to 4 carbon atoms and X is oxygen or nitrogen characterized by adding an ethylating compound containing at least one nitrogen and/or oxygen atom to the reaction product and contacting the reaction product, under conditions sufficient to produce triethylenediamine from the ethylating compound and piperazine, with a condensation/cyclization shape-selective zeolite catalyst demonstrating a triethylenediamine/piperazine weight ratio uptake value of at least 6:1.

    摘要: A process for the production of predominantly primary and secondary amines and little or no tertiary amines by the reductive amination of aliphatic alcohols using a metal exchanged crystalline aluminosilicate catalyst. The catalyst has a silica/alumina ratio ranging from about 10:1 to 40:1, contains about 1 to 10% by weight of cobalt or nickel and about 0.05 to 5% by weight of at least one other metal. High conversion rates are achieved at moderate temperatures and pressures.

    摘要: There is disclosed a method of making, through direct synthesis, a catalyst comprising an Fe-SAPO-34 molecular sieve. There is also disclosed an Fe-SAPO-34 molecular sieve made according to the disclosed method herein, wherein the molecular sieve contains both framework iron and iron cations at ion-exchange sites. In addition, there is disclosed a method of using the Fe-SAPO-34 disclosed herein in a selective catalytic reduction reaction, typically in the presence of ammonia or urea, to reduce or remove nitric oxides from exhaust emissions.
