Differences between esters and oils: 1. Different properties Ester: Ester refers to the product produced by the esterification reaction of alcohol and carboxylic acid or inorganic oxyacid in organic chemistry. Widely present in nature, for example, ethyl acetate is present in wine, vinegar and some fruits. Grease: Grease is a general term for oils and fats. Chemically speaking, oils and fats are esters of higher fatty acids and glycerol. Greases are derivatives of hydrocarbons. Grease is a special kind of ester. The oil in nature is a mixture of various substances, the main component of which is the ester formed by the dehydration of one molecule of glycerol and three molecules of higher fatty acid, called triglyceride.
2. Different chemical properties Esters: In the presence of acids or bases, esters can undergo hydrolysis to generate corresponding acids or alcohols. The hydrolysis of the ester is incomplete under the acidic condition, and the hydrolysis of the ester under the alkaline condition tends to be complete. This is because under the alkaline condition, OH- is directly added to the ester, and then the carboxylate and alcohol are obtained according to the addition and elimination reaction, In this reaction, OH- is directly involved in the reaction, not water. Grease: Grease is generally less dense than water and has no fixed melting point. When the carbon chain in the oil contains carbon-carbon double bonds (that is, unsaturated fatty acid glycerides), it is mainly a low-boiling vegetable oil; when the carbon chain in the oil is a carbon-carbon single bond (that is, saturated fatty acid glycerides), it is mainly low-boiling vegetable oil. High-boiling animal fats.
3. Different esters with different functions: lower esters are colorless liquids with fruity fragrance, which exist in the flowers and fruits of plants. For example, apples contain isoamyl valerate, bananas contain isoamyl acetate, and jasmine flowers contain methyl benzoate. , low molecular weight esters can be used as solvents, and many esters formed by branched alcohols are excellent lubricating oils. Esters can also be used in industries such as fragrances, essences, cosmetics, soaps and pharmaceuticals. Parabens: Parabens and their salts with acids have strong antitrypsin activity, strong antithrombin activity, and strong anticoagulant activity, and at the same time have low toxicity, and can be used for the treatment of pancreatic and disseminated Intravascular coagulation (DIC) agent; can also be used as a plasticizer. Fat: Provides energy. The energy density of fat is 37,000 joules per gram, or 9 calories. Fat is the densest food nutrient relative to sugars at 17,000 joules per gram and ethanol at 29,000 joules per gram.
What is the difference between lipids and esters in chemistry
Lipids are a class of bio-organic molecules that are low in water and high in non-polar solvents. For most lipids, their chemical nature is esters formed by fatty acids and alcohols and their derivatives.
Acids react with alcohols to form a class of compounds called esters, which are part of lipids in nature.
