Potassium ethoxide since any transesterification reaction does not result in ester scrambling. Potassium ethoxide is stable, but also both flammable and corrosive. The compound reacts vigorously with water. If the compound comes into contact with damp air, it may lead to the heating and ignition of the solid powder. Keep separated from air, moisture, water, acids, oxidzing agents, and reducing agents. It can also cause severe skin burns. Potassium ethoxide Potassium ethoxide, also known as potassium ethanolate, is an off-white or yellow powder with the chemical formula of CHKO. Potassium ethoxide contains an ethoxide ion, the conjugate base of ethanol, which makes
Lower flammable limit Lower flammable limit Lower flammability limit (LFL), usually expressed in volume per cent, is the lower end of the concentration range over which a flammable mixture of gas or vapour in air can be ignited at a given temperature and pressure. The flammability range is delineated by the upper and lower flammability limits. Outside this range of air/vapor mixtures, the mixture can not be ignited (unless the temperature and pressure are increased). The LFL decreases with increasing temperature; thus, a mixture that is below its LFL at a given temperature may be ignitable if heated sufficiently. For liquids, the LFL
