Abstract
A method for preparing "twin-tailed" tertiary amines which have two moles of alkoxylated phenol bonded to each nitrogen function of a molecule of methylamine and represented by the formula: ##STR1## wherein x represents zero to about 30 which comprises alkylating a mole of methylamine with two moles of alkoxylated alkylphenol over a catalyst comprising: 5 to 70% nickel; 1 to 20% copper; 0.1 to 10% chromium; and 0.1 to 10% molybdenum on an alumina support.
Claims2
A method for the synthesis of polyoxyalkylene tertiary amines having two moles of alkoxylated alkylphenol bonded to each tertiary nitrogen function which comprises:
