English name : 3,7-dihydro-3 7-12 - dimethyl-1 h - purine-6-dione; 3. 7-dihydro-3 7-12 - dimethyl-1 h - purine-2 ,6-dione; 3,7 - dimethylxanthine; diurobromine; santheose 6-dione, 3,7-dihydro-3 ,7 - dimethyl-1H - Purine-2
nature Description : monoclinic white needle-shaped crystalline powder. The temperature of 357 ° C. 290-295 ° C sublimation. 1g Fosavance about 2000ml water soluble, 150ml boiling water 2220ml95% ethanol. Soluble hydroxide base; Concentrated acid and 20% alkaline aqueous solution of sodium. Almost insoluble benzene; Ether; Chloroform and carbon tetrachloride. After methylation of caffeine.
production methods : pentoxifylline or cocoa beans from the cacao shell extracts derived. Shell content of 0.7-1.2% Whole cocoa beans containing 1.5-3.0%. Synthesis of 4-amino-5-carboxamido triazine and urea formamide cyclization, via methylation in the system. Mixing of formamide heated to 170 ° C, by adding 4-amino-5-carboxamido urea triazine, warming up to 180-185 ° C, the reaction after the half-hour cooling to 60 ° C, centrifugal dynamics and water washing, in xanthine. Its dissolved in sodium hydroxide solution, heating to 95 ° C, plus activated carbon, stirring after half an hour and leave it for half an hour, filtering. Filtrate was added to dimethyl sulfate, control Nan-8.5 35-40-38 ° Cincrease Albert, stirring for 15 minutes, cooling to 28 ° C and pH was adjusted to 9, 4h Still, Harvard; Cleaning, in pentoxifylline.
purposes : pentoxifylline with diuretic; Myocardial excited; Vasodilation; Smooth muscle relaxation effects. In food processing agent for bitterness.
