gamma acid

Thân thiện

Gamma acid is used in the laboratory to synthesize a bright red azo dye.

Definition

Noun: 1. A chemical compound used in dye manufacturing: Gamma acid is a specific, crystalline organic acid. Its primary industrial use is as a key intermediate or coupling component in the synthesis of azo dyes, which are a large class of synthetic dyes known for their vivid colors.

Usage Examples

• Noun:
  • The chemical plant increased its production of gamma acid to meet the demand from textile manufacturers.
  • This particular shade of red requires gamma acid in its synthesis.
  • Gamma acid is an important intermediate for many acid dyes.

Advanced Usage

• Technical/Industrial Context: The term is almost exclusively used within the fields of industrial chemistry, chemical engineering, and textile manufacturing. It refers to a specific, well-defined chemical structure (C10H9NO4S).
  • The purity of the gamma acid is critical for achieving consistent dye results.

Variants and Related Words

• Chemical Name: 7-Amino-4-hydroxy-2-naphthalenesulfonic acid. This is the systematic IUPAC name for the compound commonly called gamma acid.
• Azo Dye (n): A type of dye characterized by the presence of an azo group (–N=N–), many of which are synthesized using intermediates like gamma acid.
• Coupling Component (n): In dye chemistry, this is the role gamma acid often plays, reacting with a diazonium salt to form the azo dye.

Synonyms

• Intermediate (n): A substance formed during a chemical process that is then used to make another substance.
• Dye intermediate (n): A chemical compound used specifically in the production of dyes.

Notes on Meaning

This word has a single, highly specialized meaning. It is not used in everyday language and does not have idiomatic or phrasal verb forms. Its definition is tied directly to its function in industrial chemical synthesis.
