| 摘要 |
The subject of the invention is a process for the manufacture of condensation products of hydroxymethylphosphonium compounds and guanidines, characterised in that (a) 1 mol of a tetrakis-(hydroxymethyl)-phosphonium compound is condensed with (b) 0.02 to 0.5 mol, preferably 0.1 to 0.3 mol, of guanidine, guanidine salt, guanylurea, guanylurea salt or methylolated guanidine or guanylurea at 40 DEG to 120 DEG C, optionally in the presence of formaldehyde or a formaldehyde-donating agent and optionally in the presence of an inert organic solvent, optionally subsequently further condensed at temperatures of 100 DEG to 150 DEG C and, if appropriate, free hydroxyl groups are at least partially etherified with at least one alkanol with 1 to 4 carbon atoms and if appropriate the salts of the condensation products are converted into the corresponding hydroxides. |
