II. Introduction to organic bismuth catalysts
Organobismuth compoundshave green and safe properties such as low cost, easy handling, low toxicity and low radioactivity. In the past 10 years, both the synthesis of new organobismuth compounds and the research of organobismuth compounds in organic synthesis, catalysts and biomedicine have been in a stage of rapid development. Organic bismuth products produced in advanced foreign countries have a history of more than 30 years and have been supplied to the European and American markets for many years. Bismuth compounds have the following main uses: as paint driers, polyurethane catalysts; as biomedicines for ulcers, tumors and radiotherapy, etc.
Organobismuth catalysts mainly have the following advantages:
1. Promote NCO/OH reaction, avoid NCO side reactions, and reduce the generation of CO2;
2. It has better hydrolysis resistance, reduces the selectivity of reaction with water, and reduces water and NCO radicals in water-based PU dispersions.
3. Safe and environmentally friendly, it can replace lead, mercury and tin which are being abolished by legislation; 4. In a one-component system, liberate amines shielded by water instead of promoting NCO and Reaction of water;
5. Can be used alone or in combination with amines or other organic metal compounds.
6.Organic bismuthThe combination of zinc and zinc has a synergistic effect, making the formula and Production is more flexible, energy consumption is reduced, and profits are increased;
