N. N-diethylhydroxylamine is an organic compound commonly used as an important chemical reagent and industrial additive. The following is a clear description of its basic characteristics:

Chemical Structure and Properties

1. Molecular formula: C ₄ H ₁₁ NO

2. Structural characteristics: Two ethyl groups (- C ₂ H ₅) replace two hydrogen atoms in hydroxylamine (NH ₂ OH) to form N-diethyl substituted hydroxylamine derivatives.

3. Physical state: Pure products are colorless and transparent liquids, while industrial products may appear pale yellow due to impurities.

4. Solubility: Easily soluble in water and organic solvents such as ethanol, ether, chloroform, etc., with hygroscopicity.

5. Stability: Stable at room temperature, but may gradually change color (from colorless to yellow) after long-term storage or direct sunlight exposure. After intense shaking, it may temporarily become cloudy and naturally clear after a few hours.

6. Safety: It belongs to Class 3 flammable liquids, and vapors can form explosive mixtures with air; Toxic, irritating to eyes and skin, should be sealed and stored away from light, and kept away from strong oxidants.

Physical and Chemical Properties

1. Physical state: It is usually a colorless or light yellow transparent liquid at room temperature, with a special amine odor.

2. Solubility: It is soluble in water and various common organic solvents (such as ethanol and ether), making it easy to use in different systems.

3. Chemical characteristics:

Strong reducibility: can effectively capture free radicals and inhibit unnecessary oxidation reactions.

Weak alkalinity: Due to its amino structure, it can react with acids to form salts.

Thermal instability: It may decompose when heated, and high-temperature storage should be avoided.

main purpose

1. Aggregation reaction inhibitor:

Prevent self polymerization of olefin monomers (such as styrene and acrylic esters) during purification or storage.

As a terminating agent or retarder for free radical polymerization reactions.

2. Antioxidants and corrosion inhibitors:

Used for water treatment and circulating cooling systems to prevent corrosion of metal equipment.

In the nuclear industry, as an antioxidant additive in aqueous systems.

3. Organic synthesis intermediates:

Used for preparing other nitrogen-containing organic compounds, such as drugs or fine chemicals.

4. Other fields:

As an antioxidant auxiliary ingredient in rubber processing.

Reductive additives in the photography and dye industry.

Safety and storage precautions

1. Toxicity: It has a certain degree of irritation and may cause discomfort upon contact with skin, eyes, or inhalation of vapors.

2. Storage requirements:

It should be sealed and stored in a cool, ventilated place, away from heat sources and oxidants.

It is usually recommended to store in the dark to maintain its chemical stability.

3. Operation protection: It is recommended to use it in a ventilated environment and equip it with appropriate personal protective equipment (such as gloves, goggles).

brief summary

N. N-diethylhydroxylamine is a multifunctional organic compound that combines reducibility and weak alkalinity. It mainly exerts antioxidant, polymerization inhibiting, and corrosion inhibiting effects in industrial production by inhibiting free radical reactions. Its characteristics make it a commonly used functional additive in fields such as chemical engineering, water treatment, and nuclear industry.
