Development history and use of diethanol monoisopropanol
Diethanol monoisopropanolamine was produced in the 1990s. It is a non-toxic, trisamine-lowering, environmentally friendly alcohol-amine fine chemical product that is mainly used in surfactants and cement. In the fields of grinding aids, daily chemicals and fabric softeners, production and consumption are mainly concentrated in China, the United States, South Korea, India, Europe and other countries and regions. China started large-scale industrial production in 2011, and most of the consumption field is concentrated on cement grinding aids, which are used to replace triisopropanolamine and triethylpropanolamine in the grinding aid, and diethanol monoisopropanolamine. Its better adaptability and obvious advantages of early and late cement strength enhancement are favored by China's grinding aids and concrete admixture enterprises. Regardless of the process route, DEIPA's production involves the storage and use of hazardous chemical materials. With the further improvement of relevant national policies, a systematic management system has been gradually formed for the management of hazardous chemicals. For example, the Ministry of Environmental Protection has implemented the VOC (Volatile Organic Compound) pollution control and leakage detection and repair policies and regulations in the petrochemical industry. Under the new situation, only by continuously exploring and researching scientific hazardous chemicals management methods, and effectively improving the level of production management, can we achieve safe production fundamentally, in line with national requirements for safety supervision and environmental protection. Therefore, the production enterprises of DEIPA are gradually focusing on chemical specialization, large-scale and centralized production. Through the integration of the industrial chain, the development of PO or DEA and EO industries will enhance the cost advantage of DEIPA, avoid the huge risks of fluctuations in raw material prices, and achieve breakthroughs in the market cost competition. In the field of fine chemicals such as surfactants, daily chemicals, fabric softeners and pharmaceutical intermediates, the requirements for color, purity, isomers, heavy metal ions and free ammonia of DEIPA products are high. It is necessary to increase investment in the synthesis process, equipment, technology research and development, etc. to meet the individual needs of customers in the field of fine chemicals.
