WitrynaAbstract. Diethyl ether (CAS 60-29-7) is a component of starting fluids and is used as a solvent in the manufacture of synthetic dyes and plastics. Because of its characteristics diethyl ether was widely used in many countries as an anesthetic agent, but was then replaced by other substances in the 1960s. The main route of exposure is inhalation. WitrynaThe ether solution containing the naphthalene was decanted into a pre-weighed, 100mL, round-bottom flask. A rotary evaporator was used to pull off the ether. The naphthalene was weighed and transferred to a vial to dry for a week. The mass of the benzoic acid and 2-naphthol were recorded after a week of air-drying.

WitrynaDue to its smaller size, ethanol exhibits weaker dispersion forces than diethyl ether. However, ethanol is capable of hydrogen bonding and, therefore, exhibits stronger overall IMFs, which means that fewer molecules escape from the liquid at any given temperature, and so ethanol has a lower vapor pressure than diethyl ether.
