Function:
Condensation function: It can react with nitrogen-containing compounds such as ammonia, amines, and urea to generate heterocyclic compounds or polymers with specific structures and properties, and is often used to synthesize organic compounds such as drugs and resins.
Redox function: Glyoxal has a certain reducing property and can be oxidized to products such as oxalic acid under certain conditions; it can also participate in some reactions as a weak oxidant and undergo redox reactions with reducing substances.
Application:
Textile industry: As a fiber treatment agent, it is used to increase the shrinkage and wrinkle resistance of cotton, nylon and other fibers. It is a durable pressing finishing agent that can keep the fabric in good shape and wrinkle resistance after multiple washings.
Adhesive field: It can be used as an insoluble adhesive for gelatin, animal glue, cheese, polyvinyl alcohol and starch, etc. Through cross-linking, these materials form a strong bonding structure, improving the bonding strength and water resistance of the adhesive.
During the leather tanning process, glyoxal can undergo a cross-linking reaction with the collagen in the leather, increasing the leather’s water resistance, wear resistance and wrinkle resistance, thereby improving the quality and durability of the leather.
