#ethyl

• Alkyl — A generic name given to monovalent, saturated, acyclic hydrocarbon radicals, theoretically obtained by removing a hydrogen atom from an alkane. They possess the general molecular formula CnH2n+1 and are structurally named by replacing the suffix '-ane' of the corresponding alkane with the suffix '-yl' (e.g., methyl, ethyl, propyl, butyl), serving as fundamental components in organic compound synthesis.
• Alcohol — An organic compound containing one or more hydroxyl (-OH) functional groups bound to a saturated carbon atom. In common parlance, the term refers to ethanol or ethyl alcohol, a volatile, flammable liquid obtained through the fermentation of sugars or chemical synthesis, acting as the active ingredient in intoxicating beverages and an essential solvent in industry and pharmacy.
• Antifreeze — A liquid chemical substance (usually based on ethylene glycol or propylene glycol) which, when added to water in the cooling systems of internal combustion engines or industrial installations, considerably lowers its freezing point and prevents structural damage to pipes due to ice expansion; antifreeze. As an adjective, it describes the property of a compound to prevent the solidification of fluids at low temperatures.
• Antifreeze — A special liquid (usually composed of ethylene glycol or propylene glycol) added to the water in cooling systems of internal combustion engines or heating installations, aiming to lower the freezing point of the mixture and prevent pipe damage; a concentrated coolant.
