31. It is soluble in hydrocarbons, benzene, and cyclohexane , and in greases including those used in lab equipment. 32. Alternatively, another industrial route involves the reaction of cyclohexane with nitrosyl chloride, which is a free radical reaction. 33. In 1959, Scientific Design announced a boron-mediated process for the oxidation of cyclic aliphatics such as cyclohexane . 34. For example carbon disulfide only needs a third the pressure, and with cyclohexane only a quarter pressure is required. 35. Cynthia Simpson, environmental director for the plant, said styrene, butadiene and cyclohexane were being burned in the fire. 36. These two are considered functional group isomers because cyclohexane is a cycloalkane and hex-1-ene is an alkene. 37. When the piperidine ring of raloxifene is replaced by cyclohexane , the ligand loses antiestrogenic properties and becomes a full agonist. 38. C17-C20 ladderane lipids from anammox bacteria containing three linearly concatenated cyclobutane rings and one cyclohexane or five cyclobutane rings. 39. The forward rate k 1 was found to decrease by a factor of 4.5 going from cyclohexane to methanol. 40. Beyond the examples highlighted below, other classic examples include the Cope rearrangement in bullvalene and the chair inversion in cyclohexane .
