The active substance of this mixture was purified and the structure elucidated [13]. The compound is an acylphloroglucinol and was named rhodomyrtone (Rom). Rom and its isomer, rhodomyrtosone B, could be chemically synthesized; both isomers showed similarly high antimicrobial activity [14]. Rom...
All the water is evaporated by the thermal energy of flue gas during sufficient residence time for SO2 and other acid gases (HCl, SO3) to react with hydrated lime, which forms a mixture of solid calcium compounds (CaSO3, CaSO4, CaCl2). Since all the water is evaporated, the mixture of ...
Using the invention, the 1-benzotriazolylcarbonate ester can be formed in a single step and without using phosgene, thereby avoiding the safety and quality problems associated with that compound. The method of the invention includes providing a water-soluble and non-peptidic polymer having at least...
6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of oxygen...
