Camphor boiling point

SBA is a colorless, high boiling point (212°F) liquid with a pleasant odor. TBA, on the other hand, is a white solid (melting point is 78°F) with a camphor-like odor. Both alcohols are traded as technical grade (99% purity) and need a hazardous (corrosive) materials label. 

Brown camphor oil is a fraction with a boiling point higher than that of camphor (ca. 20%). It is a pale yellow to brown liquid with the characteristic odor of sassafras oil. 

Expensive special thermometers are usually needed for determinations of freezing-point depression and boiling-point elevation but, when camphor is used, a common lab thermometer may be employed. A student mixes 0.1032 g... 

With other solvents, e.g., oil of turpentine, pinewood oil, light mineral oils, resin, tar, shale or camphor oil, the density and boiling point may be determined and various other determinations made, such as the rotation, refractive index, solubility in aniline, behaviour towards fuming nitric acid. The special reactions of resin oil, pinewood oil, shale oil and camphor oil may also be applied. 

Camphorene Cyclic compound, found in the high boiling fraction of camphor oil, boiling point (b.p.) 177-178°C. 

Is the following statement true or false Explain your answer. When determining the molar mass of a solute using boiling-point or freezing-point data, camphor would be the best solvent choice of all of the solvents listed In Table 11.5. 

One example of a solid that exhibits significant vapor pressure is camphor, for which a portion of its sublimation curve is shown in Fig. 2. This compound exhibits the classic pressure-temperature profile [11], finally attaining a vapor pressure of 422.5 torr at its melting point (179.5°C). When heated above the fusion temperature, only a short vaporization curve is possible since the boiling point of camphor is reached at 207.4°C. 

Brown and Walker also electrolyzed the sodium-ethyl salt of camphoric acid and obtained two esters which they were able to separate by means of fractional distillation. One of these (boiling-point 212-213°) on being saponified yielded an unsaturated monobasic acid, C,H 0, campholytic acid the other, having a higher boiling-point (240-242°), was the neutral ester of a dibasic acid, C,bH,(,0, to which Walker gave the name of camphothetic acid. The experiments are of great importance, because they prove the dibasic nature of camphoric acid, a fact which is doubted by Friedel. 

Robert Schiff (Frankfurt a.M., 25 July 1854-Massa, Carrara, 1940), nephew of H. Schiff, professor of general chemistry in Modena (1879), worked on organic chemistry (particularly on camphor), but also on physical properties of liquids (molecular volume and capillary constant at the boiling-point). ...
