化学的特性
Naphthenic acid is a gold to black, odorless
liquid.
使用
The term naphthenic acid, as commonly used in the petroleum industry, refers collectively to all of the carboxylic acids present in crude oil.
一般的な説明
NAPHTHENIC ACID is a dark colored liquid with an offensive odor. NAPHTHENIC ACID is insoluble in water. NAPHTHENIC ACID will burn though NAPHTHENIC ACID may take some effort to ignite. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since NAPHTHENIC ACID is a liquid NAPHTHENIC ACID can easily penetrate the soil and contaminate groundwater and nearby streams. NAPHTHENIC ACID is used to make paint dryers, detergents, and solvents.
空気と水の反応
Insoluble in water.
健康ハザード
Principal effect is that of mild primary irritation when encountered in high concentrations. Inhalation of vapor causes coughing. Liquid is moderately irritating to eyes and slightly to moderately irritating to skin; excessive exposure could result in dermatitis.
安全性プロファイル
Moderately toxic by
ingestion and intraperitoneal routes. When
heated to decomposition it emits acrid
smoke and irritating fumes.
職業ばく露
Used to make metallic naphthenates
for paint dryers and cellulose preservatives. It is also used
as a solvent; detergent, rubber reclaiming agent. Used in
catalysts, cutting oils; drilling compounds; rust inhibitors;
surfactants, emulsions, grease, and wood preservatives.
輸送方法
UN3082 Environmentally hazardous substances,
liquid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous
hazardous material, Technical Name Required.
不和合性
Compounds of the carboxyl group react
with all bases, both inorganic and organic (i.e., amines)
releasing substantial heat, water, and a salt that may be
harmful. Incompatible with arsenic compounds (releases
hydrogen cyanide gas), diazo compounds, dithiocarbamates,
isocyanates, mercaptans, nitrides, and sulfides
(releasing heat, toxic, and possibly flammable gases), thiosulfates
and dithionites (releasing hydrogen sulfate and
oxides of sulfur). Incompatible with sulfuric acid, caustics,
ammonia, aliphatic amines; alkanolamines, isocyanates,
alkylene oxides; epichlorohydrin, strong oxidizers.
Corrosive to metals.
