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 boiling point of CH 2 _2 2 F 2 _2 2 is greater than CH 4 _4 4 due to the same principle that one has a stronger IMFA present. The IMFAs present in CH 2 _2 2 F 2 _2 2 are dipole-dipole interaction (DDI) and London dispersion forces. DDI is observed in all polar molecules where dipole moments are present. LDF is present in all molecules. notebook battery health check
