This last factor is perhaps the one which is most feasibly controlled In the pigaent synthesis* 9* The resints of this study have not lead to any single means for the oontrol of the reactivity of "Haphthanll" Maroons* Any further work of a fundamental nature should involve a study of the surface structure of the pigment and its bearing cm reactivity* n addition it would be desirable to determine the importance of particle size using purified samples of the same chemical composition* GESERAL DlgargglOt In this study attention was directed towards two chemical types of "lapflbthsaail" Maroons, They result from the couplings of (1) 5-nitro-2-aHd.no anisole with "Haphthanll* A8-D, and (2) p-chloro-nitre aniline with "Haphthanilw AS-D# DUP050150672 5-nitro-2amino anisole H "Waphthanil" AS-D RT-551-D RT-500-D RT-501-D p-chlor-oniteroaniline "Naphthanil" AS-D The alkaline coupling of the former type (1) is the basis for th manufacture of RT-551-D.
