The production of 1,3-propanediol is gradually increasing, and biological fermentation is the mainstream preparation method.

1,3-Propanediol (PDO), also known as 1,3-dihydroxypropane, is a polymer material formed from polymer monomers. The chemical formula of 1,3-propanediol is C3H8O2. Under normal temperature and pressure conditions, it mostly appears as a colorless and viscous liquid with a slightly salty taste. It is miscible in water and organic solutions such as ethanol and ether. 1,3-propanediol has the advantages of good solubility and stability, but it is prone to spontaneous combustion under high temperature conditions.

At present, the 1,3-propanediol preparation technology is very mature and can be roughly divided into chemical methods, biological fermentation methods, etc. Among them, chemical methods have gradually withdrawn from the market due to shortcomings such as high production costs and serious environmental pollution. The biological fermentation method has become the main preparation method for industrial production of 1,3-propanediol due to its advantages of green environmental protection, low production cost and high product yield.

From the upstream of the industrial chain, the raw materials for 1,3-propanediol mainly include glucose, glycerol, acrolein, ethylene oxide and other raw materials. Among them, glycerin is the main raw material for the production of 1,3-propanediol. Glycerin has a wide range of applications, and is mostly used in sealing, food, medicine, skin care and other fields. Driven by downstream market demand, my country’s glycerin market has gradually expanded. In 2022, my country’s glycerin market size will be 7.831 billion yuan, a year-on-year increase of 4.2%.

From the perspective of application fields, 1,3-propanediol is mainly used in PTT fiber, cosmetics, medicine and other fields, among which PTT fiber is the largest application field of 1,3-propanediol. As a new type of polyester fiber with excellent comprehensive properties, PTT fiber has the advantages of softness, wear resistance, high gloss, good air permeability, and strong hygroscopicity. It is mostly used in the production of automobile mats, bedding, sportswear, and carpets. Products such as these are widely used in home textiles, automotive interiors, clothing, home decoration and other fields. Driven by downstream market demand, my country’s PTT fiber market has developed rapidly, driving the gradual growth of 1,3-propanediol market demand.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on 1,3-Propanediol Industry 2023-2027” released by the Industrial Research Center , with the rapid development of terminal application fields such as home textiles, clothing, and medicine in my country, the market demand for 1,3-propanediol, as a basic raw material, is gradually increasing. Against this background, the production scale of my country’s 1,3-propanediol enterprises has gradually expanded, and output has increased. In 2022, my country’s 1,3-propanediol production will be approximately 19,500 tons.

Industry analysts said that at present, my country’s largest 1,3-propanediol companies mainly include Huaheng Biological and Qingda Zhixing , Meili Rong, Su Zhen Biology, etc. In recent years, my country’s 1,3-propanediol industry has developed rapidly, and competition among enterprises has intensified. In order to seize market share, my country’s 1,3-propanediol companies need to continuously increase investment in product research and development, optimize production technology, and develop more high-quality products.
