What are Carboxylic Acid chlorides?
Carboxylic acid chlorides are organic compounds. These compounds contain a –COOH group, this atom can attach to either hydrogen atoms or Alkyl group. Examples of Carboxylic acid chlorides include the following;
- Acryloyl Chloride
- Methacryloyl Chloride
- Trimesoyl Chloride
- 2-Furoyl Chloride
- Butyryl Chloride
- Cyclohexane Carbonyl Chloride
- 3-Chloropropionyl Chloride
- 2-Chloropropionyl Chloride
- Cyclopropanecarbonyl Chloride
More Information About Carboxylic Acid Chlorides
Carboxylic Acid chlorides are acidic due to the hydrogen in the –COOH group. The Acidity of the Carboxylic acid chloride is generally more so than other organic compounds but the acidity is weaker than those in familiar mineral acids such as sulphuric acid.
Carboxylic Acids have high boiling points ranging from 97.2 degrees to 118 degrees. When you add water to a Carboxylic acid chloride it does not combine with the molecules within the water to form a dimer. Instead there are hydrogen bonds formed between the water and the acid molecules. The carboxylic acid chlorides with higher molecular weights are often solid at room temperature and almost all of the salts of the carboxylic acid are solids.
In nature there are many carboxylic acids that can be found, the fatty acids are components of glycerides and these are in turn components of fat. There are components of hydroxyl in citric acid found in fruit and lactic acid found in sour milk. Keto acids are found in most living cells and proteins contain amino acids which also contain carboxyl groups
Many of the derivatives of carboxylic acid chlorides include formic acid, it is used as a disinfectant and also in textile treatment and as an acid reducing agent. Cellulose plastics often use Acetic acid. An ester of salicylic acid prepared from acetic acid is asprin which is widely used as a pain killer in day to day life. The use of stearic acid and palmitic acid is used when making many soaps, pharmaceuticals, protective coatings, cosmetics and candles. Oleic acid is also widely used in many soaps, detergents and treating textiles.
The carboxylic acid that are fatty acids and liquid at room temperature have very foul odours specifically butanoic acid.
