Study of the effect of amines on structure of coacervates formed by photochemical effect on metal ions in presence of formaldehyde.
If an aqueous mixture of ammonium molybdate, diammonium hydrogen phosphate, biological minerals, and formaldehyde is exposed to sunlight, typical "Jeewanu", mixtures are observed. However, if a little solution of p-phenylene diamine, p-nitroaniline, alpha-naphthylamine or beta-naphthyl amine is added to it, a dense white precipitate is obtained. This precipitate, under a microscope at X1200 magnification, appears as large clusters of very tiny cream-coloured spherules. But if the mixture is first exposed to sunlight for four hours, when the formation of typical microstructures appears, and then the amine solution is added, the formation of the precipitate is retarded as the exposure time of amine-free mixture is enhanced, till finally the formation of spherules as precipitate is stopped. Microscopic study in twenty days of exposure of the amine-containing mixture tube shows that the number of typical microstructures decreases; they get larger in size and gradually disintegrate, while the formation of tiny sdpherules is accelerated.
