Introduction to 1, 3-propylene glycol 1, 3-propylene glycol (PDO) is a kind of polymer material with excellent synthesis properties. 1, 3-propylene glycol is a high-end technology product, and the production technology is currently dominated and controlled by three companies: Shell, Du Pond and Degussa, Germany. They basically do not sell 1, 3-propylene glycol raw materials, and the original technology is not open to the public. Only PTT slices and its downstream products are provided to customers. 1, 3-propylene glycol can be used in the synthesis of plasticizers, detergents, preservatives, emulsifiers, and can also be used in food, cosmetics and pharmaceutical industries. At present, 1, 3-propylene glycol is mainly used in the production of PTT fiber resin products (PTT refers to propylene glycol terephthalate). 1 Propylene process (acrolein process) Degussa, a German company, developed an industrial route to produce PDO using acrolein as raw material and applied for a patent.
