Properties of diethanol monoisopropanolamine

physical and chemical properties Diethanol monoisopropanolamine (Diethanol monopropanolamine, DEIPA for short) is an organic compound with a colorless to light yellow liquid appearance. Its molecular formula is C7H17NO3 and its molecular weight is 163.22g/mol. DEIPA has high viscosity and low volatility, and is easily soluble in polar solvents such as water and ethanol, but not easily soluble in non-polar solvents such as benzene and ethyl ether. Its boiling point is about 240°C and its flash point is 130°C, which makes it corrosive.

chemical reaction activity DEIPA has the reactivity of typical alcohol amine compounds, and can react with acids, acid anhydrides, isocyanates and the like to generate various derivatives. DEIPA can also react with epoxy compounds to generate the corresponding alcohol and amine derivatives, and its reactivity makes it have important application potential in the synthesis of various chemical products.

Use of diethanol monoisopropanolamine

cement grinding aid The main application of DEIPA in the cement industry is as a cement grinding aid. The main function of cement grinding aids is to improve the dispersion of cement particles, thereby improving the fineness and strength of cement. DEIPA improves the production efficiency of the mill by reducing the electrostatic attraction and mechanical resistance between the cement particles, and can significantly improve the early strength and final strength of the cement.

polyurethane foam stabilizer In the polyurethane industry, DEIPA can be used as a foam stabilizer, particularly in the production of rigid polyurethane foams. It can improve the uniformity and stability of the foam, thereby improving the quality of the finished product. The addition of DEIPA to the formulation also improves the mechanical properties of the foam, giving it better durability and thermal insulation.

Lubricants and metalworking fluids DEIPA is also widely used in the metal processing industry. As one of the components of lubricants and metalworking fluids, DEIPA has good lubrication performance and anti-rust effect, which can extend the service life of equipment and reduce wear and corrosion during processing.

Diethanol monoisopropanolamine upstream and downstream raw materials

Upstream raw materials The production of DEIPA involves several key upstream feedstocks. The main raw materials include propylene oxide and diethanolamine. Propylene oxide reacts with diethanolamine to produce DEIPA through a catalytic ring-opening reaction. In this process, the reaction conditions need to be controlled to ensure high purity and high yield of the product.

production process A typical process for the production of DEIPA is the reaction of propylene oxide with diethanolamine at a certain temperature and pressure. The crude product formed by the reaction was subjected to distillation and purification steps to obtain pure DEIPA product. This process involves complex process control and precise equipment operation to ensure product quality and production efficiency.

Downstream Applications DEIPA has a wide range of downstream applications, involving multiple industries. Its main downstream products include cement grinding aids, polyurethane foam stabilizers, lubricants and metalworking fluids. DEIPA can also be used to produce chemical products such as detergents, fabric softeners and emulsifiers.

Diethanol monoisopropanolamine storage method

Storage conditions Because DEIPA is corrosive and hygroscopic, its storage requires special attention. Storage containers shall be made of corrosion resistant materials, such as stainless steel or plastic containers, avoid the use of metal containers to prevent corrosion. The container should be well sealed to prevent moisture from entering and avoid moisture absorption and deterioration of the product.

Environmental requirements DEIPA should be stored in a cool, dry and well-ventilated environment, away from direct sunlight and high temperatures. The storage temperature should be controlled between 10-30°C to prevent product decomposition and performance degradation. Keep away from fire and heat sources, and avoid mixing with dangerous chemicals such as strong oxidants and acidic substances.

Safety protection Safety precautions should be taken when handling and storing DEIPA. Operators should wear protective gloves, protective glasses and protective clothing to avoid direct contact with skin and eyes. The storage area shall be equipped with emergency flushing equipment and fire fighting equipment to deal with possible emergencies such as leaks and fires.
