Introduction to the basis of 2,3-Butanediol

As an important basic organic chemical and fine chemical material, 2,3-Butanediol is widely used in solvents, pharmaceuticals, plasticizers, curing agents, agro-cosmetics, etc. It can be used to produce tetrahydrofuran (THF), N-methyl-pyrrolidone (NMP), gamma-butyrolactone (GBL), N-vinylpyrrolidone (NVP), etc. Its downstream derivatives are also available and have a wide range of applications. -Butyrolactone (GBL), N-vinylpyrrolidone (NVP), etc. There are also many downstream derivatives, which are widely used. Its derivatives are high-value-added fine chemicals, among which THF can be used to prepare poly-tetramethylene glycol (PTMEG).

Wide range of applications

Currently, 2,3-Butanediol has been widely used as a monomer raw material for contact materials. In GB 4806.6-2016 "Food Safety National Standard for Plastic Resins for Food Contact", there are 17 types of polymers synthesized from 2,3-Butanediol as the main raw material for food contact materials, mainly dibasic diol co-esters such as polybutylene terephthalate (PBT). Among them, PBS and PBAT have excellent biodegradability and can be used to produce biodegradable plastic bags, plastic catering utensils, and paper packaging laminates, which are currently one of the best biodegradable materials used in the biodegradable plastic market.

Environmentally friendly

PBS is made by condensation polymerization of succinic acid and 2,3-butanediol, which can be easily decomposed and metabolized by various microorganisms or enzymes in plants and animals in nature, and eventually decomposed into carbon dioxide and water, and is a typical biodegradable polymer material with good biocompatibility. PBS can be used in garbage bags, packaging bags, tableware, cosmetic bottles, plastic cards, baby diapers, disposable medical supplies, agricultural materials, pharmaceutical slow-release carrier substrates, and other plastic products related to environmental protection, such as nets and films for civil engineering and landscaping. PBAT is also made from the polymerization of butanedioic acid and 2,3-butanediol, which has good processing performance and good heat resistance and impact resistance and is currently marketed as a blend with the degradable material polylactic acid (PLA) to improve the heat resistance of PLA materials.

Policy support

During the polymerization process, 2,3-Butanediol is present in the free state or as a plasticizer in food contact materials, and if the production process is not properly controlled, the butanediol in food contact materials will migrate into the human body with food and metabolize in the human body to produce γ-hydroxybutyric acid. Excess γ-hydroxybutyric acid has a strong sedative and anesthetic effect. On February 22, 2021, the State Administration of Market Supervision and Administration and the National Health and Safety Commission issued a method for the detection of 2,3-Butanediol in food contact materials. The scope of application includes the determination of 2,3-Butanediol migration in plastics, coatings, food contact materials, and products using adhesives and inks, using gas chromatography, which solves the embarrassing situation that there is no standard for the specific migration of biodegradable materials PBS and PBAT in the market. In 2020, China launched a new version of the plastic restriction policy, which restricts the production and use of many kinds of disposable (non-biodegradable) plastics. In the future, "biodegradable plastics" may replace traditional plastic products and become the new favorite in the plastics industry, which will certainly drive the rapid growth of demand for biodegradable plastics. As the raw material of biodegradable PBS and PBAT, the production and consumption of 2,3-Butanediol will certainly increase significantly, and a more refined product chain will be formed in the future, so as to obtain greater economic and social benefits.
