abietic acid
C2Formal, Technical
Definition
Meaning
A crystalline carboxylic acid derived from pine resin.
A diterpenoid carboxylic acid (C₁₉H₂₉COOH) that is the primary resin acid component of rosin. It is used in the production of varnishes, ester gums, paper sizing agents, and some soldering fluxes.
Linguistics
Semantic Notes
The term is purely scientific/industrial and lacks colloquial uses. Its primary meaning is chemically specific. It is a hyponym of 'resin acid'.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'кислотный' (acidic) in a general sense; it is a specific compound name: 'абиетиновая кислота'.
Common Mistakes
- Misspelling as 'abiatic acid' or 'abeitic acid'. Using 'abietic' as a general adjective (e.g., 'an abietic substance').

Frequently Asked Questions
It can be a skin irritant and sensitizer in concentrated forms, but it is not highly toxic under normal handling conditions in industry.
Indirectly, yes. It's a key component in rosin used for soldering, in some paper products, and in certain varnishes and adhesives.
Rosin is the solid residue from distilled pine resin, of which abietic acid is the major chemical constituent (often 50-90%).
It derives from the Latin 'abies' meaning 'fir tree', reflecting its botanical source, though it is primarily obtained from pines.
