[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of isopropanolamine, the price of isopropanolamine has skyrocketed.

Properties of Isopropanolamine

Basic physical properties Isopropanolamine (Isopropanolamine, IPA) is a colorless to pale yellow liquid with a hygroscopic and ammonia odor. Its chemical formula is C3H9NO and its molecular weight is 75.11g/mol. Under normal temperature and pressure, isopropanolamine is easily soluble in water, ethanol, acetone and other organic solvents, with good hydrophilicity and solubility. Its boiling point is about 160 ° C, melting point is about -60 ° C, flash point is 85 ° C, these properties make it stable at room temperature, but at high temperatures easy to decompose and release ammonia.

Chemical Properties Isopropanolamine is an organic base with typical properties of amines. It can be neutralized with acid to generate salt, can react with acid chloride, acid anhydride to generate the corresponding amide, but also can occur esterification, alkylation and other reactions. Because of its structure has both hydroxyl and amine groups, it has multiple reactivity in industrial synthesis and chemical reactions.

Isopropanolamine use

Industrial Solvents Isopropanolamine is widely used as an industrial solvent, especially in the fields of coatings, paints, resins, dyes, etc. It can effectively dissolve a variety of organic compounds, and its volatility is low, reducing the risk of environmental pollution.

Intermediate In chemical synthesis, isopropanolamine is used as an intermediate to synthesize a variety of chemical products. For example, in the pharmaceutical industry, it can be used to produce beta-blockers, anti-allergy drugs, etc. In the field of pesticides, it is used in the synthesis of herbicides and insecticides.

Surfactant Since isopropanolamine has an amphoteric structure, it can be used as a raw material for the production of surfactants. These surfactants are widely used in cleaning agents, detergents, emulsifiers and other products to improve their decontamination, foaming, emulsification and other properties.

Upstream raw materials

Acetone Acetone is one of the main raw materials for the production of isopropanolamine. Through a reduction reaction, acetone can be converted to isopropanol, which is further reacted with ammonia to form isopropanolamine. The supply stability and price fluctuation of acetone directly affect the production cost of isopropanolamine.

ammonia gas Ammonia is another important raw material. In industrial production, ammonia can be supplied from ammonia synthesis plants or decomposed from other nitrogen-containing compounds. The purity and supply of ammonia gas have a direct impact on the production efficiency and product quality of isopropanolamine.

Downstream Products

pharmaceutical intermediates Isopropanolamine can be used to synthesize a variety of pharmaceutical intermediates, such as antiarrhythmic drugs, antidepressants and so on. These drugs have significant effects on the treatment of cardiovascular diseases and mental diseases, and the market demand is large.

Pesticides In the field of pesticides, isopropanolamine is used in the production of herbicides, insecticides, etc. For example, glyphosate, a widely used herbicide, is present as its isopropanolamine salt. Its good water solubility and stability make it widely used in agricultural production.

Surfactants and cleaners Isopropanolamine is used to synthesize various surfactants. These surfactants have good detergency, emulsification and dispersion properties, and are widely used in household cleaners, industrial cleaners, personal care products and other fields.

storage method

Container Selection Isopropanolamine should be stored in a closed container to avoid contact with moisture and carbon dioxide in the air to prevent its hygroscopicity leading to quality degradation. Corrosion-resistant materials such as stainless steel, FRP or special plastic containers are recommend used.

Environmental requirements The storage environment should be kept cool, dry and well ventilated, and avoid direct sunlight and high temperature environment. The temperature should be controlled between 15-25 ℃, and the relative humidity should be lower than 75%. Keep away from fire and heat sources to avoid fire risk.

Safety protection Because isopropanolamine has certain toxicity and corrosiveness, operators should wear protective gloves, protective glasses and protective clothing during handling and storage to avoid direct contact with skin and eyes. Storage areas should be equipped with emergency showers and eye irrigators for emergency use.

Periodic inspection Check the tightness and integrity of the storage container regularly to ensure that there is no leakage and corrosion. Clean and ventilate the storage area regularly to keep the environment clean and safe.

Conclusion

As an important chemical product, isopropanolamine has broad application prospects. Its unique physicochemical properties allow it to play a key role in multiple industries. By understanding its nature, use and upstream and downstream raw materials, we can better grasp its market dynamics and development trends. In actual operation, strictly following storage and safety protection measures to ensure product quality and operational safety is the key to ensure its efficient application.
