Nonylphenol химические свойства, назначение, производство
Химические свойства
Pale-yellow, viscous liquid; slight phenolic odor.Insoluble in water;
soluble in most organic solvents. Combustible.
Использование
Nonylphenol (NP) is an alkylphenol and together with its derivatives, such as trisnonylphenol phosphite (TNP) and nonylphenol polyethoxylates (NPnEO), they are used as additives in the plastic industry, e.g., in polypropylene where nonylphenol ethoxylates are used as hydrophilic surface modifiers or as stabilizer during crystallization of polypropylene to enhance their mechanical properties. They are also used as antioxidant, antistatic agents, and plasticizer in polymers, and as stabilizer in plastic food packaging materials.
Определение
A mixture of isomeric monoalkyl phenols, predominantly p-substituted.
Общее описание
A thick, yellowish liquid with a slight phenolic odor. Insoluble in water. Flash point 285°F. Burns although difficult to ignite. May irritate the skin. Used in the manufacture of oil additives, surfactants, fungicide preparations and plastics and rubber.
Реакции воздуха и воды
Insoluble in water.
Профиль реактивности
Nonylphenol behaves as a very weak organic acid. Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Likely to react exothermically with concentrated sulfuric acid and nitric acid.
Угроза здоровью
Moderately toxic if swallowed. Severely irritating to skin and eyes.
Пожароопасность
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Химическая реактивность
Reactivity with Water: No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Профиль безопасности
Moderately toxic by ingestion andskin contact. A severe skin and eye irritant. Combustiblewhen exposed to heat or flame. When heated todecomposition it emits acrid smoke and irritating fumes
