A simple and practical method for the synthesis on a large scale of altretamine (1), a wellknown antitumor drug, has been successfully developed. The synthesis method involves the conversion of cyanuric chloride (2) into altretamine (1) by dimethylamination of 2 with an aqueous solution of 40% dimethylamine and potassium hydroxide in 1, -dioxan 4in one step to give altretamine (1) in high yield.

AbstractThe present work investigates the performance of Ga-doped ZnO (GZO) and Ca-doped ZnO (CZ) nanopowders as an efficient nanomaterials for the removal of lead ions from aqueous solutions. The sol–gel method was used to synthesise the nanoparticles from zinc acetate dihydrate. To incorporate Ca and Ga in ZnO, adequate quantities of calcium chloride hexahydrate and gallium nitrate hydrate were added to ZnO, and supercritical drying conditions of ethyl alcohol were used. Different Ca and Ga concentrations (1, 2, 3, 4, 5 at.%) were used to synthesise CZ and GZO. The structural and morphological properties of the as-prepared nanoparticles were determined using X-ray diffraction and transmission electron microscopy. Batch-mode experiments were used to remove lead from aqueous solution and to determine the adsorption equilibrium isotherms of lead ions using ZnO doped by 3 at.% of weight of Ca (CZ3) and Ga (GZO3). The effects of temperature, contact time, and pH on the removal of lead ions from aqueous solution by CZ3 and GZO3 were studied.

In this paper, a new simple approach has been developed for the preparation of α- Fe 2 O 3 microspheres by a facile hydrothermal method using PVP as a surfactant. Uniform α- Fe 2 O 3 microspheres could be routinely synthesized through solvothermal approach by controlling the PVP/ FeCl 3⋅6 H 2 O ratio. The as-obtained α- Fe 2 O 3 microspheres exhibit high efficiency on the decolorization of RhB aqueous solution in the presence of H 2 O 2 at room temperature.

AbstractIntramolecular nanocavities in polyamidoamine (PAMAM) are usually used as a good template to synthesize nanoparticles. In this paper, TiO2 nanoparticles were prepared successfully by the interspaces of the hydrogen network between PAMAM. The possible mechanism was that PAMAM could form the steady microspheres with many interspaces in ammonia aqueous solution at pH=10. The interspaces of the hydrogen network could act as the template for preparing TiO2 nanoparticles. The results were proved by transmission electron microscopy (TEM) and X-ray diffraction (XRD).

1. Ammonia nitrate possesses the somewhat remarkable property of combining with large quantities of ammonia. The product is a liquid the composition of which varies with the temperature and pressure to which it is subjected. It appears from its properties to be a solution of ammonia nitrate in liquefied ammonia, analogous in every respect to an aqueous solution of a salt, its formation being a phenomenon precisely like that of the deliquescence of a salt in a moist atmosphere. 2. The liquid was prepared by bringing dry ammonia gas into contact with dry ammonia nitrate in a flask loosely closed by a vulcanized caoutchouc stopper (to diminish loss of ammonia by diffusion) and imbedded in ice. The tube conveying the ammonia passed through the stopper and reached nearly to the bottom of the flask.
