Abstract:
The invention relates to chemical engineering processes, and more particularly to liquid-phase catalytic methods for producing, in the presence of hydrogen, alkylated para-anisidine for use as a chemical substance or as a gasoline additive for increasing the octane rating of a gasoline. The technical result of the claimed group of inventions is an increase in the yield of N-methyl-para-anisidine and a decrease in the yield of a dimethyl derivative. A method for producing N-methyl-para-anisidine in a liquid phase includes alkylating para-anisidine with formalin as they are separately, simultaneously fed into a mixer disposed in a reactor, directly upstream of a catalytic reduction zone, thus producing an intermediate azomethine, and subsequently reducing same on a hydrogenation catalyst at a temperature of 20-120° C. in an environment of hydrogen at elevated pressure, and then isolating the target product, N-methyl-para-anisidine.

Claim (Index 5):
The method according to  claim 1 , wherein stabilizers are used during the alkylation in the form of tertiary aliphatic amines, wherein said stabilizers are used in the amount of 5-10 mol % of the para-anisidine load.
