ChemSpider record containing structure, synonyms, properties, vendors and database links for Caffeine, 58-08-2, guaranine.
The chemical formula is C 8 H 10 N 4 O 2 . Caffeine has a molar mass of 194.19 grams (6.85 ounces). It is soluble in water and in many organic solvents, and it appears in pure form as white crystals. Caffeine can be prepared by extraction from natural sources or by synthesis from uric acid.
26 sie 2024 · Pure caffeine (trimethylxanthine) occurs as a white powder or as silky needles, which melt at 238 °C (460 °F); it sublimes at 178 °C (352 °F) at atmospheric pressure. It is very soluble in hot water; upon cooling, the solution deposits crystals of caffeine monohydrate. Caffeine is generally less soluble in organic solvents than in hot water.
2 cze 2019 · Caffeine (C 8 H 10 N 4 O 2) is the common name for trimethylxanthine (systematic name is 1,3,7-trimethylxanthine or 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione). The chemical is also known as coffeine, theine, mateine, guaranine, or methyltheobromine.
26 lis 2023 · Understanding the solubility of caffeine in water is crucial for industries that manufacture caffeinated beverages and for individuals who want to manage their caffeine intake. It also explains why caffeine can be easily extracted from coffee beans or tea leaves when they are steeped in hot water.
The solubility of caffeine in water is 2.2 mg/mL at 25°C, 180 mg/mL at 80°C, and 670 mg/mL at 100°C. It is quite soluble in dichloromethane, the solvent used in this experiment to extract the caffeine from water. Table of Physical Constants. Chemical Name.
