1,4-butanediol
Thread Content
Dear friends, please discuss the prospects of using formaldehyde and calcium carbide to produce 1,4-butanediol?
Much better than the benzene method, the cost of using the acetylenic aldehyde method, that is, the formaldehyde carbide method is between the C4 method and the benzene method. Efficiency and competitiveness are possible. It’s just that the environmental issues of calcium carbide powder are difficult to deal with.
Nowadays, there are many companies under construction or completed and started in the domestic BDO industry. What everyone is mainly fighting for is production costs.
Currently, the maleic anhydride method is favored for BDO production.
in my opinion: 1. The production of butanediol by the acetylenic aldehyde method has the advantages of low cost, low energy consumption, and high profit. However, the product quality is 99.95%, and the changes in many parameters are not obvious. The most fundamental thing is the production process itself. :) 2. The maleic anhydride method can increase the purity of the product to more than 99.98%. This production process can achieve a very high purity, will occupy the high-end market, and provide a good platform for the synthesis of downstream products.
Catalysts for the acetylenic aldehyde method are not easy to buy!
