2-Propylheptanol (2-PH) can synthesize new plasticizers, but the number of manufacturers in my country is small

2-Propylheptanol, also known as isodecanol, 2-propyl-1-heptanol, abbreviated as 2-PH, chemical formula is C10H22O. It appears as a colorless and transparent liquid at room temperature. It is insoluble in water and soluble in General organic solvents. 2-Propylheptanol is an important organic chemical raw material and one of the most widely used products among high-carbon alcohols. It can be used to synthesize surfactants, plasticizers, adhesives, etc. Among them, plasticizers are an important In the application market, it can be used to manufacture polyvinyl chloride (PVC) products with better performance.
2-Propylheptanol reacts with phthalic anhydride to produce di(2-propylheptyl) phthalate (DPHP for short), which can be used as a plasticizer. Traditional polyvinyl chloride uses dioctyl phthalate (DOP for short) as a plasticizer, which has poor high temperature resistance, water resistance, and oil resistance, and cannot meet the increasing market requirements. Compared with DOP polyvinyl chloride, polyvinyl chloride made with DPHP as plasticizer has better performance in terms of high temperature resistance, water resistance, weather resistance, electrical insulation, low atomization, low volatility, etc., and is cheaper. Therefore, DPHP has become a new plasticizer for the production of polyvinyl chloride, and the market demand for 2-propylheptanol continues to expand.
Globally, the number of 2-propylheptanol manufacturers is relatively small, mainly including Dow-Davidson of the United States, BASF of Germany, Evonik of Germany, and Perstorp of Sweden. The reason is that only a few companies have mastered the production technology. In the Chinese market, there are only three 2-propylheptanol manufacturers, namely Yangzi BASF, Shenhua Baotou, and Yanchang Petroleum. In 2010, Yangzi BASF built an 80,000-ton/year 2-propylheptanol unit using basf technology. In 2013, Shenhua Baotou Coal Chemical Branch completed a C-IV comprehensive utilization 2-propylheptanol unit, using davy technology.
According to the “2021-2025 2-Propyl Heptanol (2-PH) Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center It shows that before 2019, only two companies in my country, Yangzi BASF and Shenhua Baotou, had the production capacity of 2-propylheptanol. my country’s 2-propylheptanol production capacity is small, which limits the development of downstream industries. In 2019, the butanol/2-propylheptanol co-production unit introduced by Yanchang Petroleum Yan’an Nenghua Company successfully produced products. This is the world’s first industrialized production unit of butanol/2-propylheptanol. The scale of my country’s 2-propylheptanol industry is constantly expanding.
Industry analysts said that the performance and quality requirements of plastic products in our country are constantly improving. As the main plastic product, polyvinyl chloride has a market The space is large, but its performance has certain drawbacks, which limits its application in automobiles, cables, building materials and other fields. DPHP plasticizer helps to improve the performance of polyvinyl chloride, has better environmental performance and is low-priced. It will replace DOP and become the mainstream plasticizer of polyvinyl chloride. Against this background, my country’s 2-propylheptanol market prospects broad. However, at this stage, the number of 2-propylheptanol manufacturers in my country is small, and they mainly introduce foreign technology and do not have independent production capabilities. The industry still has great room for improvement in terms of technological breakthroughs and production capacity expansion.
