| titleOfInvention | Surface active compounds comprising phenoxy-polyethoxy-propylamines |
| abstract | The invention comprises compounds of the formula <FORM:0937683/IV(a)/1> where the alkyl substituents in the alkylphenyl group have a total of 6-18 carbon atoms, NRR1 is a secondary amino radical and n is an integer from 1-100, together with salts and quaternary ammonium derivatives of the amines. The compounds may be prepared by reacting an alkylated phenol, containing 6-18 carbon atoms in the alkyl group(s), first with an epihalohydrin to yield an alkylphenylglycidyl ether, then with a secondary amine to yield an alkylphenyl-2-hydroxy-3-propyl amine fully substi-tuted on the nitrogen atom, and then with 1-100 mols. of ethylene oxide. Alternatively, a condensation product from an N,N-disubstituted amine and an epihalohydrin may be condensed with the alkylated phenol and the product then reacted with ethylene oxide. In either event the products may be finally quaternized, e.g. with methyl iodide or dimethyl sulphate. In examples octyl, nonyl and dodecyl phenols are reacted with epichlorhydrin to give glycidyl ethers, the ether is reacted with a secondary amine such as a dialkylamine, aryl alkyl-amine, aralkyl alkylamine or a cyclic amine such as piperidine or morpholine, and the resulting 3-alkylphenoxy-2-hydroxy-propylamine is condensed with ethylene oxide to give products containing 16-50 ethenoxy units.ALSO:The invention comprises compounds of the formula <FORM:0937683/IV(a)/1> where the alkyl substituents in the alkylphenyl group have a total of 6-18 carbon atoms, NRR1 is a secondary amino radical and n is an integer from 1-100, together with salts and quaternary ammonium derivatives of the amines.
