bosschemNAPHTHENIC ACID Basic information Product Name: NAPHTHENIC ACID Synonyms: NAPHTENIC ACID;NA
1338-24-5
Product name: Naphthenic Acid
English alias: Naphthenic acids; Acids, naphthenic; Petroleum naphthenic acids
CAS: 1338-24-5
Molecular formula: Complex mixture of carboxylic acids, primarily CnH2n-2O2
Appearance: Dark brown viscous liquid
Package: 25kg/drum, 200kg/drum, IBC tank
Naphthenic Acid is a complex mixture of carboxylic acids naturally occurring in petroleum, specifically derived from the refining of petroleum distillates. These acids are characterized by having one or more saturated ring structures (cycloparaffins) attached to a carboxylic acid group. The exact composition varies depending on the crude oil source and refining process. Naphthenic acid is valued for its metal reactivity, making it a key raw material in producing metal soaps (naphthenates), which are widely used as catalysts, driers, and wood preservatives. Its corrosive nature also makes it a significant topic in petroleum refining.
测试项目 (Test Item) | 单位 (Unit) | 典型结果 (Result (Typical)) |
酸值 (Acid Value) | mg KOH/g | 180 - 230 |
皂化值 (Saponification Value) | mg KOH/g | 190 - 245 |
水分含量 (Moisture Content) | % | ≤ 1.0 |
黏度 (40°C) (Viscosity) | mPa·s | 100 - 500 |
相对密度 (20/20°C) (Specific Gravity) | - | 0.96 - 0.98 |
闪点 (Flash Point (COC)) | °C | ≥ 90 |
颜色 (Color) | - | ≤ 12 (Gardner) |
Naphthenic Acid is corrosive and can cause severe skin burns and eye damage. It is harmful if swallowed. Inhalation of mist or vapors may cause respiratory irritation. Proper personal protective equipment (PPE), including chemical-resistant gloves, eye protection, and protective clothing, is essential when handling. Ensure adequate ventilation. The environmental impact of naphthenic acids, particularly their toxicity to aquatic organisms, is an area of ongoing study.
Store in a cool, well-ventilated area away from heat and ignition sources. Keep container tightly closed to prevent moisture absorption and contamination. Store away from strong oxidizers, bases, and reactive metals.
Naphthenic Acid is classified as a Class 8 Corrosive substance for transport. It is typically supplied in 25 kg or 200 kg sealed steel or plastic drums, or in 1000 kg IBC totes (Intermediate Bulk Containers). All packaging must comply with international regulations for corrosive materials (e.g., IMDG, IATA, ADR).
