Product Description

Production MethodsEdit Broadcast
There are three main routes for the synthesis of diethanol monoisopropanolamine (DEIPA): first, ammonia reacts with ethylene oxide (EO) and propylene oxide (PO) respectively; MIPA) and EO are produced by the reaction; third, it is synthesized from diethanolamine (DEA) and PO.
Ammonia and epoxy olefin reaction route
This route is a tertiary series reaction. Ammonia reacts with EO to generate monoethanolamine, diethanolamine and triethanolamine. The reactants are then synthesized with PO, and the target product is obtained after purification. Alternatively, ammonia and PO are reacted to generate monoisopropanolamine, diisopropanolamine and triisopropanolamine, the reactants are then synthesized with EO, and the target product is obtained after purification. In the process of producing DEIPA by this method, two feedings and purifications are required, and the equipment investment is large. As of the end of 2016, there is no related device for this process in the world.


MIPA route
This route is generated by a two-step reaction between MIPA and EO. In the first step, MIPA reacts with EO to generate N-(2-hydroxyethyl)-isopropanolamine, and in the second step, N-(2-hydroxyethyl)-isopropanolamine and EO continue to react to generate DEIPA. This reaction process is a series of reactions, but the raw material MIPA is only produced by a few companies in the world, and it is mainly used in fine chemical industries such as medicine, pesticides, textiles, and cosmetics. Due to certain problems and risks in the cost and supply of MIPA raw materials, only one company in my country has a MIPA production plant, which has the advantage of self-producing raw materials. Related reports have also mentioned its 50,000-ton modified isopropanolamine plant project.

DEA Route
This route uses the reaction of DEA and PO to generate the target substance DEIPA. The advantages of this route are that the reaction rate is fast, the selectivity of the reaction is high, and the supply of raw materials is sufficient and stable. The production of DEIPA in my country is currently all produced by this route, but there are differences in the production equipment of reactors or pipeline reactions, and differences in product isomers and quality stability.

Usages
Diethanolamine monoisopropanolamine is mainly used as a surfactant, widely used in chemical raw materials, pigments, pharmaceuticals, building materials and other fields, and is widely used in cement additives, skin care products and textile softeners.
At present, in the field of cement grinding aids, most of its formulations are single or compound products of chemical raw materials such as alcohols, alcoholamines, acetates, etc. Compared with other similar cement additive products, diethanol monoisopropanolamine (DEIPA) Compared with other alcohol amine products, it has great advantages in improving grinding efficiency, saving energy and reducing consumption and improving cement strength. The cement grinding aid patents disclosed in US7160384 and US6048393 show that diethanol monoisopropanolamine can greatly improve the specific surface area of cement in terms of grinding aid performance, and can simultaneously enhance the early and late strength of cement.
In the field of softener application, the Journal of Sur-factants and Detergents, Vol.4, (October, 2001) shows that the diester quaternary ammonium salt softener prepared from diethanol monoisopropanolamine has good biodegradability, flexibility and manufacturing costs have great advantages.
