Carboxylic acids, C6-18 and C8-15-di- - Introduction
Carboxylic acids are a class of organic compounds that contain a carboxyl group (-COOH). C6-18 and C8-15-di-means between 6 and 18 and between 8 and 15 carbon atoms.
The general properties of boxylic acids include:
1. They are acidic and can react with bases to form salts and water.
2. Usually has a pungent smell.
3. Most are colorless liquids, but there are also some solid or waxy acids.
4. Soluble in water and organic solvents.
The specific properties of C6-18 and C8-15-di-depend on the carbon chain length and the position of the substituents.
Use:
1. Carboxylic acids are commonly used in the preparation of pharmaceuticals, spices, food additives, dyes and synthetic resins.
2. Carboxylic acid esters are an important class of solvents used in paints, coatings and cleaners.
Production method:
1. Carboxylic acids can be prepared by oxidizing aldehydes or alcohols. A common method is to use an acid oxidizing agent such as potassium permanganate (KMnO4) or dilute sulfuric acid.
2. Some specific carboxy acid can be produced by microbial fermentation process.
Safety Information:
1. Carboxylic acids are irritating. It is recommended to wear protective gloves and glasses when using them to avoid contact with skin and eyes.
2. Long-term exposure to high concentrations of boxylic acids may have negative health effects, such as respiratory problems and skin allergies. Therefore, attention should be paid to ventilation in use.
3. Please follow the correct storage and disposal methods, avoid mixing with oxidants or other chemicals to prevent dangerous reactions.
