摘要:
A new process for the manufacture of low molecular reactive surface-active agents from carbamides, which comprises reacting a monomethylol compound of a carbamide, which is optionally etherified with a monohydric alcohol with 4 to 7 carbon atoms, with a hydrophobic or hydrophilic hydroxy compound thereafter introducing a second methylol group into the ether compound thus obtained by means of formaldehyde or a formaldehyde donor, and etherifying this methylol group with a hydrophilic or hydrophobic hydroxy compound in such a way that the end product contains at least one hydrophobic and one hydrophilic group.
摘要:
New carbamide-formaldehyde condensation products which possess at least one hydrophilic radical and at least one hydrophobic radical, wherein at least one hydrophobic radical is bonded directly or via an oxygen or
bridge, wherein A denotes hydrogen or alkyl with one to four carbon atoms, and at least one hydrophilic radical is bonded via a N-methylol-ether bridge, to an amino-1,3,5-triazine radical; these products are particularly useful as reactive surfaceactive agents.
