What is isopropylbenzylamine used for ? It is a common organic base, an important organic synthesis raw material that can be used as an intermediate for the synthesis of compounds, and also as a precursor for the production of certain drugs. N-benzylisopropylamine and magnesium form amine adducts at room temperature in toluene.Bis (cyclopentadienyl) magnesium was prepared and characterized with N-benzyl isopropylamine as ligand. It is also used in the synthesis of N-benzyl isopropylamine.
Drug Synthesis: Isopropylbenzylamine is commonly used as an intermediate in the synthesis of drug compounds, and is involved in the synthesis process of many drugs. Due to its similarity with methamphetamine in appearance and physical properties, it has special significance in drug development and production.
Drug precursor: It can also be used as precursor for the production of certain drugs, which provides a possibility for the development of new drugs.
2. organic chemical raw materials
Organic synthetic raw materials: as an important organic synthetic raw material, Isopropylbenzylamine has a wide range of applications in the chemical field. It can be used to prepare various organic compounds to meet different chemical needs.
Rust inhibitor: Due to its special chemical properties, it is also used as a rust inhibitor for protecting metal surfaces from corrosion and oxidation.
The application of Isopropylbenzylamine as a rust preventive agent is mainly due to its unique chemical structure and properties.
Adsorption:
The Isopropylbenzylamine molecule has both polar and non-polar groups that form a dense protective film on metal surfaces. This film is tightly adhered to the metal surface through a combination of physical adsorption and chemical adsorption, effectively isolating the metal from direct contact with corrosive media such as oxygen and water, thus slowing down or preventing the corrosion process from occurring.
Corrosion inhibition:
In addition to physical isolation, Isopropylbenzylamine can react with the active sites on the metal surface to form a stable compound layer.
This compound layer not only enhances the adhesion of the protective film, but also further improves the corrosion resistance of the metal. At the same time, it neutralizes acidic or alkaline substances on the metal surface, reducing the occurrence of corrosion reactions.
Self-healing ability:
In some cases, metal surfaces may be exposed to unprotected areas due to scratches, abrasion, and so on. However, Isopropylbenzylamine, as a rust preventive agent, has the self-healing ability to re-form a protective film on these exposed areas, thus maintaining the long-term rust prevention effect of the metal.
Highly effective:
Isopropylbenzylamine as a rust preventive agent has a remarkable rust prevention effect. Even in harsh corrosive environments, it can effectively protect metal surfaces from damage.
Environmentally friendly:
lower toxicity and less environmental impact than traditional rust preventives. It does not contain heavy metals, halogens and other harmful substances, which meets the requirements of environmental protection and is conducive to sustainable development.
Wide applicability:
Isopropylbenzylamine is suitable for antirust treatment of a wide range of metal materials, such as iron, steel, copper, aluminum and so on. Meanwhile, it can also be used in conjunction with a variety of coatings, oils and greases, etc., to improve the antirust effect and service life.
Application Examples
Automobile manufacturing:
In the process of automobile manufacturing, Isopropylbenzylamine is widely used in the antirust treatment of body, chassis and other metal parts. Through spraying or dipping, the rust preventive agent is evenly coated on the metal surface to form a solid protective film, ensuring the corrosion resistance of automobiles under harsh road conditions.
Machinery Manufacturing:Isopropylbenzylamine is also used as a rust preventive treatment for machinery and equipment in the machinery manufacturing industry.
The rust preventive agent is applied to key parts of the equipment, such as gears and bearings, through immersion and brushing to improve the corrosion resistance and service life of the equipment.
Aerospace:
In the aerospace field, the corrosion resistance of metal materials is highly required, Isopropylbenzylamine, as a high-performance antirust agent, is widely used in the antirust treatment of metal parts of airplanes, rockets and other aerospace vehicles, to ensure their safety and reliability in extreme environments.
The steps for generating N-benzylisopropylamine through oxidation can be divided into the following parts: synthesis of N-benzylisopropylamine, oxidation of N-benzylisopropylamine, and reduction of N-benzylacetone.,
C6H5CH2NH2+CH3COCH3 → C6H5CH2N(CH3)CH2CH3+H2O
The synthesis of N-benzylisopropylamine typically involves the reaction of benzylamine with acetone. The specific steps are as follows:
(1) In a dry round bottomed flask, add benzylamine (100 mmol) and acetone (60 mL), and add a small amount of anhydrous calcium chloride desiccant.
(2) Stir the mixture until completely dissolved.
(3) Add excess hydrogen chloride gas to the mixture.
(4) Stir the reaction mixture at room temperature for at least 2 hours. After the reaction is complete, adjust the pH value to neutral using a saturated sodium carbonate solution and extract with a saturated sodium chloride solution.
(5) Transfer the organic phase to a dry round bottomed flask and use ammonium sulfate desiccant to remove residual moisture.
(6) Purify the product through distillation or column chromatography.
C6H5CH2N(CH3)CH2CH3+[O] → C6H5CH2C(O)CH2CH3+H2O
In this step, we oxidize N-benzylisopropylamine to N-benzylacetone. This reaction typically involves the use of hydrogen peroxide (H2O2) or other oxidants. The specific steps are as follows:
(1) Add N-benzylisopropylamine (100 mmol) and anhydrous ethanol (20 mL) to a dry round bottom flask.
(2) Stir the mixture until completely dissolved.
(3) Slowly add hydrogen peroxide (30% w/w) to the mixture and keep stirring.
(4) Control the reaction temperature at 0-5 ° C and stir the reaction mixture at room temperature for at least 1 hour.
(5) After the reaction is complete, extract with saturated sodium chloride solution. Transfer the organic phase to a dry round bottomed flask and use ammonium sulfate desiccant to remove residual moisture.
(6) Purify the product through distillation or column chromatography.
C6H5CH2C(O)CH2CH3+H2+Ni → C6H5CH2N(CH3)CH2CH3+H2O
In this step, we reduce N-benzylacetone back to N-benzylisopropylamine. The specific steps are as follows:
(1) Add N-benzylacetone (100 mmol) and acetone (20 mL) to a dry round bottom flask.
(2) Stir the mixture until completely dissolved.
(3) Add hydrogen gas and use sodium methoxide as a catalyst.
(4) Control the reaction temperature at room temperature and stir the reaction mixture at room temperature for at least 2 hours.
(5) After the reaction is completed, filter the reaction mixture through filter paper and concentrate it.
(6) Purify the product through distillation or column chromatography.
