Isosorbide, also known as isosorbide, 1:4;3:6-dianhydro-D-sorbitol, the molecular formula is C6H10O4. Isosorbide is a dehydrated derivative of sorbitol. As a secondary dehydrated derivative of sorbitol, isosorbide is a bio-based material and a widely used chemical intermediate. It has significant application value and is widely used in many fields such as medicine, cosmetics, food, plastics and polymers.

At present, the industrial production of isosorbide mainly uses cereal starch as raw material. Glucose is obtained through depolymerization of starch, which is then hydrogenated to form sorbitol. Sorbitol removes a molecule of water to obtain sorbitan, which is further dehydrated to obtain isosorbide.

Isosorbide was initially mainly used in the pharmaceutical field to treat diseases such as cerebral edema. It can also be used as a raw material for the preparation of cardiovascular drugs isosorbide mononitrate. It is also an effective osmotic oral diuretic; isosorbide has It has the unique function of improving polymer properties and is used as a copolymer to synthesize modified commercial polymers, such as PET, polyether, polyester, polyurethane, polycarbonate, etc. It can also be used for packaging bottles of hot liquids or viscous liquids. wait.

At this stage, the main companies in the isosorbide industry include DuPont, Mitsubishi Chemical, Changchun Dacheng Industrial Group Co., Ltd., etc.

According to the “Global and China Isosorbide Industry In-Depth Research Report 2023” released by the Industrial Research Center, in recent years, my country’s isosorbide industry The overall demand for sorbitol maintains a steady growth trend, mainly due to the development and promotion of pharmaceutical, food, plastics and other industries. In 2022, China’s demand for isosorbide will be approximately 2,800 tons. In the future, as the downstream pharmaceutical, food, plastics and other fields continue to develop under the support of national policies, the domestic market demand for isosorbide will continue to increase.

Industrial researchers personnel said that isosorbide can be widely used in medicine, cosmetics, food, plastics and polymers and other fields. In the field of polymers, isosorbide is used to modify existing polymers, improve their physical properties, and improve the performance of polyesters. In addition, citric acid ester plasticizers synthesized from isosorbide and citric acid can avoid the potential hazards caused by the use of chemical raw materials, and have become a hot research topic. In the future, as the research on isosorbide further deepens, its application fields may continue to expand. Coupled with the continued development of existing fields, the market demand for isosorbide will continue to grow, and it has good development prospects.
