The production process of 11117-11-6, also known as PHBV (poly-hydroxy-butyrate-valerate), is an important process in the chemical industry that involves several steps.
PHBV is produced by the fermentation of renewable biomass, such as corn starch or sugar beet, using microorganisms.
The resulting fermentation broth is then purified, polymerized, and processed into PHBV granules or pellets.
The first step in the production process of PHBV is the preparation of the fermentation broth.
This involves the production of glucose and sucrose from the biomass through enzymatic hydrolysis.
The resulting sugars are then used as the carbon source for the fermentation process.
The fermentation process is carried out using a microorganism, such as Alcaligenes eutrophus, which has the ability to metabolize the sugars and produce PHBV.
The fermentation process is carried out in a batch or continuous fermenter, and the microorganisms are typically grown on a solid or liquid substrate.
After the fermentation process is complete, the fermentation broth is collected and purified to remove any impurities that may have been produced during the fermentation process.
This typically involves the use of filtration and precipitation techniques.
The purified fermentation broth is then polymerized to produce PHBV.
This involves the condensation of the polymer chains, which are formed by the action of water on the fermentation broth.
The resulting PHBV is then processed into granules or pellets, which are stable and have good flow properties.
The final step in the production process of PHBV is the drying and sterilization of the PHBV granules or pellets.
This is necessary to remove any moisture that may be present and to ensure that the PHBV is free of any contaminants.
The drying and sterilization process typically involves the use of a vacuum dryer or a fluid bed dryer.
The production process of PHBV is a complex and multi-step process that requires the use of specialized equipment and techniques.
However, the end product is a versatile and environmentally friendly bioplastic that has a wide range of applications in the packaging, textile, and automotive industries.
