4-ethylmorpholine In Resin Industry
The application of 4-ethylmorpholine in the resin industry is mainly reflected in the following aspects:
1. Functional properties as a catalyst for polyurethane resin:
4-ethylmorpholine is a medium-strength tertiary amine catalyst that plays a key role in producing polyurethane resins (especially polyester polyurethane soft foam). It can optimize the foaming process, improve the uniformity of the foam and the performance of the skin formation, and promote the gel reaction in the later stage of foam molding, so that the pores can be fully expanded, thereby improving the flexibility and durability of the product.
Application case: For example, in the production of polyurethane soft foam, 4-ethylmorpholine can replace traditional cobalt salt catalysts, reduce the risk of discoloration, and make the finished product close to colorless and transparent (such as artificial marble, bathtubs, and other high-end resin products).
2. Solvents and intermediates in resin synthesis Solvent function:
4-ethylmorpholine has good solubility in oils and resins and is often used as a solvent for resin synthesis reactions to promote raw material mixing and reaction efficiency. For example, the preparation of epoxy resins and acrylic resins, it can improve the uniformity of the reaction system.
Intermediate application: As an organic synthesis intermediate, it participates in resin modification or functionalization reactions. For example, it can be used as a crosslinker or plasticizer for synthetic resins to improve the mechanical strength or weather resistance of the final product. Chemicalbook
3. Curing agent and reaction regulation Curing system optimization:
In the room temperature curing of unsaturated polyester resins, 4-ethylmorpholine can be used as an auxiliary curing agent to synergize with main curing agents such as methyl ethyl ketone peroxide to reduce the amount of cobalt salt accelerator (reduce discoloration problems) while maintaining the curing speed.
Technical advantages: A company has improved the color stability of the resin after curing by adding 4-ethylmorpholine, which is suitable for bathroom and decorative materials with strict appearance requirements.
4. Environmental protection and process innovation Green process promotion:
As environmental protection policies become stricter, the application of 4-ethylmorpholine in low VOC (volatile organic compound) resin systems has attracted attention. For example, as a co-solvent for water-based resin coatings, it reduces dependence on traditional toxic solvents.
5. Market and production data Industry scale:
The demand for N-ethylmorpholine in the domestic resin industry has been growing steadily, and some companies have purchased hundreds of tons annually.
Technology trend:
Combined with advanced production processes such as the gas phase method, the purity of N-ethylmorpholine can reach more than 99%, meeting the quality requirements of high-end resin products for raw materials.
Summary:
4-ethylmorpholine realizes the comprehensive value from process optimization to product performance improvement in the resin industry through multiple roles such as catalyst, solvent, and intermediate, and is irreplaceable in the fields of high-performance polyurethane and environmentally friendly coating resins.
