Học thuậtThân thiện
Definition
- Noun:
- An unsaturated liquid carboxylic acid: A clear, corrosive liquid organic compound with a pungent odor, characterized by having a carbon-carbon double bond (unsaturated) and containing both a carboxyl group (-COOH) and a vinyl group (CH2=CH-). Its chemical formula is C3H4O2.
- A monomer used in manufacturing: The primary, fundamental chemical building block (monomer) used in the industrial synthesis of various polymers and copolymers, most notably acrylic resins, plastics, and superabsorbent materials.
Usage Examples
- Noun:
- The laboratory synthesized a batch of high-purity acrylic acid for the experiment.
- Acrylic acid is a key raw material in the production of paints and adhesives.
- Handling acrylic acid requires proper safety equipment due to its corrosive nature.
Advanced Usage
- Technical/Industrial Context: In chemistry and manufacturing, "acrylic acid" specifically refers to the monomer, distinguishing it from its polymerized forms (e.g., polyacrylic acid).
- The stability of the acrylic acid during storage is crucial to prevent premature polymerization.
Variants and Related Words
- Acrylate (n): A salt, ester, or conjugate base of acrylic acid. (e.g., ).
- Polyacrylic acid (n): The polymer formed by the chain reaction of many acrylic acid molecules.
- Acrylic resin (n): A broad class of synthetic polymers derived from acrylic acid, methacrylic acid, or other related compounds.
Synonyms
- Propenoic acid (n): The systematic IUPAC name for acrylic acid.
- Ethylenecarboxylic acid (n): An alternative historical name.
Related Phrases/Compounds
- Acrylic acid derivatives: A category encompassing all compounds chemically derived from acrylic acid, such as its esters, salts, and amides.
- Glacial acrylic acid: A term for purified, water-free acrylic acid which can solidify at relatively low temperatures.
Noun
- an unsaturated liquid carboxylic acid used in the manufacture of acrylic resins
