Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a reaction pot. Background Art

[0002] Polyglycerol fatty acid ester (PGFE) is a new type of green and environmentally friendly surfactant. Its main structure is a lipophilic fatty acid group at one end and a hydrophilic polyglycerol structure at the other end. This type of surfactant is degraded into fatty acids and glycerol in nature or organisms. It has been proven to be a green and non-toxic surfactant product. Due to the complexity and instability of its synthesis process, it has only been gradually applied to the food and cosmetics market since the late 1970s. Later, due to its green environmental protection, low irritation and other reasons, it began to be used in many emerging fields. Since the hydrophile-lipophile balance value (HLB value) of the product can be adjusted according to the degree of polymerization of polyglycerol and different choices of fatty acids, products with HLB values ​​of 2 to 16 can be prepared. Therefore, it can be widely used in the food field.
