Recently, the draft environmental impact assessment report for Wanhua Chemical’s TPAM project entered the public comment phase. The new project is planned to be located in the western area of Wanhua Yantai Industrial Park, within the existing facility area for specialty amines, and will primarily produce isopropyl amines, including monoisopropylamine (MIPA), diisopropylamine (DIPA), and triisopropylamine (TIPA). Isopropanolamine is an alkanolamine chemical with both an amino group and alcoholic hydroxyl groups; it possesses the combined properties of amines and alcohols. There are mainly two preparation methods: the propylene oxide method and the calcium cyanamide method. Among them, the propylene oxide method is the mainstream production process, that is, it is prepared through a mixed reaction of propylene oxide (PO) and ammonia. By changing the feeding ratio of propylene oxide and ammonia, different types of isopropanolamine can be produced. The advancement of this 10,000-ton project indicates that it has mastered the technology for large-scale production of high-quality isopropylamine. At the same time, the project is also a typical example of Wanhua Chemical’s integrated strategy of \"petrochemicals–fine chemicals\". PO is an important raw material for isopropylamine. It is reported that Wanhua Chemical has an annual production capacity of over 1 million tons of propylene oxide; in its Yantai industrial park, it operates a PO/AE integrated plant with an annual capacity of 750,000 tons, as well as a project for producing 400,000 tons of propylene oxide per year (POCHP). As a green and environmentally friendly fine chemical raw material with excellent performance, isopropylamine has a wide range of applications; it can be used in the synthesis of surfactants, industrial and household cleaners, desulfurizing agents for oil and gas processing, curing agents, cement additives, intermediates for pharmaceuticals and pesticides, the production of titanium dioxide, metal cutting, electronic cleaning, the synthesis of methylenediamine, and coatings, among other fields. The product consumption market spans multiple regions around the world.
