Abstract

Six kinds of new aminoalkyl phosphonic acid or aminoalkyl phosphinic acid derivatives with mono-dialkylamino, or di-dialkylamino functional groups in the molecule were synthesized and their smoke densities were tested. The aminoalkyl phposphonic acid or aminoalkyl phosphinic acid derivatives were synthesized with quantitative yields of 90~98.6% by one step reaction of the phosphorus acid or hypo phosphorous acid with amine and aldehyde. The smoke density was measured by the ASTM E 662 method. Values of the smoke density were obtained from 224.5 to 256.6. The smoke density of the compounds with two aminoalkyl structures decreased more than that of compounds with one aminoalkyl structure. In addition, there was no correlation between the smoke density and the number of carbon atoms in the alkyl group attached to the amino group.
