Chemical Structure
13-Propanediol CAS#504-63-2
Packing of 13-Propanediol

Production

1,3-Propanediol is mainly produced by the hydration of acrolein. Another route involves the hydroformylation of ethylene oxide to form 3-hydroxypropionaldehyde. Subsequent hydroformylation of the aldehyde yields 1,3-propanediol. Biotechnological routes are also known.

Two other routes involve the bioprocessing of certain microorganisms.

DuPont Tate & Lyle BioProducts enables the transformation of glucose by transgenic E. coli strains (see: Bioseparation of 1,3-propanediol). An estimated 120,000 tons were produced in 2007.” According to DuPont, the Bio-PDO process uses 40% less energy than conventional processes, and the American Chemical Society awarded the Bio-PDO research team the “2007 Heroes of Chemistry” award for the successful development of a renewable Bio-PDO process by DuPont and Tate & Lyle.
The process uses Clostridium diolis bacteria and Enterobacteriaceae to convert glycerol (a byproduct of biodiesel production).

What is 13-Propanediol?

  • With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 13-Propanediol which has developed particularly rapidly in recent years. Do you know about 13-Propanediol?
  • The official answer:13-Propanediol (propane-1,3-diol) is a compound with molecular formula C3H8O2 and molecular weight 76.10. It is a colorless transparent viscous liquid. It can be used in the synthesis of many kinds of drugs, new polyester PTT, pharmaceutical intermediates, and new antioxidants.

What’s the application of 13-Propanediol?

Hydroformylation of ethylene oxide: firstly, ethylene oxide is hydroformylation with syngas to HPA, and then hydrogenated to 1,3-PDO. the key of the Shell process is the use of carbonyl cobalt catalyst in the hydroformylation process, and the use of various ligands (such as Chemicalbook diphosphine, tri-hydro phosphine, tri-hydro arsenic, etc.) and additives (tetrabutyl phosphonium acetate, butyl pentyl pyridine, etc.), based on ethylene oxide, the yield of 1,3-PDO can reach 85%-90%, and the product purity can reach 99.6% (mass ratio).

Applications

Colorless or light yellow viscous liquid with slightly irritating salty odor and diluting properties. Miscible with water, ethanol, acetone, chloroform (trichloromethane), ether, and other solvents, insoluble in benzene. Used in organic synthesis, synthesis of many kinds of drugs, and new antioxidants. Antifreeze agent. Solvent. Organic synthesis. Gas chromatography analysis standard. Used in the synthesis of many kinds of drugs, new polyester PTT, pharmaceutical intermediates, and new antioxidants.

WHY THEY SAY TO US

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
