The sulfur-iodine cycle is currently being researched as a feasible method of obtaining hydrogen, but the concentrated, corrosive acid at high temperatures poses currently insurmountable safety hazards if the process were built on large-scale.英文部分来自Wikipedia 参考资料: http://dxchong.bokee.com/...
In the synthesis and preparation of ROSE BENGAL sodium salt for I labeling, the method of condensing tetrachlorophthalic anhydride and resorcinol and then substituting iodine is used. Tetrachlorophthalic anhydride is synthesized by using phthalic anhydride and chlorine in fuming sulfuric acid medium with...
strongest organic acids, easily soluble in water.Use carbon disulfide as raw material, with the reaction of iodine pentafluoride to produce trifluoromethyl disulfide.(CF3S) 2Hg was obtained when reacting with mercury; Then through oxidation of hydrogen oxide, trifluoromethanesulfonic acid is acquired....
fuming sulfuric acid as a catalyst to catalyze m-cresol and isopropyl alcohol through sulfonation and alkylation to prepare thymol. However, the fuming acid sulfuric acid is too corrosive and the process is not environmentally friendly enough. (2) Using decalin as the solvent, alpha-pinene is ...
It is a dense, reddish-brown liquid which evaporates easily at room temperature to a red vapor with a strong, chlorine-like odor. Bromine is less reactive than chlorine or fluorine but more reactive than iodine.Element Bromine - Br Comprehensive data on the chemical element Bromine is provided...
