Triisopropanolamine has broad prospects and industry demand continues to increase

Triisopropanolamine is an organic surface-active material. It is an amino alcohol obtained by the addition reaction of propylene oxide and ammonia in a molar ratio of 1:1. The product is a colorless or slightly light yellow oily liquid. Poisonous, non-flammable, alkaline, slightly mild ammonia smell. The molecule of triisopropanolamine contains both amino groups and alcoholic hydroxyl groups, so it has the comprehensive properties of amines and alcohols. It has wide industrial uses and is an important basic chemical raw material.

At present, the main technology for domestic triisopropanolamine products is to use propylene oxide and ammonia as raw materials to produce it through polymerization reaction. Taking the Jiahua chemical production process as an example, the specific process is as follows: propylene oxide and ammonia water undergo a polymerization reaction through an atomizing nozzle device, and the crude product enters the distillation kettle to heat up and dehydrate to obtain triisopropanolamine product. During the production process, a The advanced “ammonia recovery and recycling technology” converts excess ammonia during the reaction process into ammonia water, the reaction raw material, through a two-stage recovery device, realizing the recycling of ammonia and achieving clean production. Most foreign companies use 60-90% ammonia solution as raw material and adopt a continuous production method. The reaction pressure is 6-8Mpa, which requires high-pressure equipment. The investment in production equipment is large and the process is relatively complex.

According to the “China Triisopropanolamine Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028” released by the Industrial Research Center It shows that from 2019 to 2022, the penetration rate of triisopropanolamine in the cement field will continue to increase, and its application and development in the pharmaceutical field will gradually deepen, causing the global triisopropanolamine market size to continue to grow. In 2022, the global triisopropanolamine market size will be approximately 4 billion yuan, a year-on-year growth of 6.0%.

Global triisopropanolamine production is mainly concentrated in several developed countries in Europe and the United States. The main companies include Dow Chemical of the United States, BASF of Germany, Bayer of Germany, etc. These companies have the world’s leading production technology and their products are highly competitive in the international market. . In recent years, China has increased investment in technology research and development, and the production technology level of triisopropanolamine has been continuously improved. It has gradually become one of the important producing countries of triisopropanolamine, and a number of outstanding companies such as Hongbaoli and Jiahua Chemical have emerged. However, compared with European and American countries, China’s triisopropanolamine production technology level still lags behind to a certain extent, and its products are mainly mid- to low-end.

Industry researchers said that in cement and cement concrete applications, triisopropanolamine has better dispersion than ethanolamine. It has the advantages of good, better late-stage enhancement performance, good environmental performance, affinity, and little harm to the human body and the environment. Therefore, it is a good substitute for ethanolamine. However, developed countries such as Western Europe have issued the “Pollutant Emission and Transfer” Registration System”, which lists ethanolamine as a hazardous substance, greatly speeding up the progress of replacing ethanolamine with triisopropanolamine. In addition, with the advancement of technology, new technologies and new uses of triisopropanolamine will be developed and broadened, and its properties will be applied in new fields. The triisopropanolamine industry has a broad market and development space.
