Using dimethyldithiophosphetane and paraformaldehyde as raw materials, 3,4-dimethylpyrazole phosphate was prepared through four steps: condensation, cyclization, dehydrogenation, and salt formation, achieving a purity of 99.2% and an overall yield of 89.6%. This process is simple, has low production costs, high yield, and is suitable for industrial production.
What do you need this technology for? To work on a project?
One of my friends wants to join this project; if you have the skills, feel free to contact me
Uh. This is pure chemical engineering. You might need to turn to professional design firms (there are only a few such firms), so you can get in touch with them. But the price for getting them will definitely be high.
The design institute won’t do the design either, unless you tell them everything! ! !
The design institute won’t do it either, unless you provide them with some parameters.
I don’t know if the process package for this project is available. If there is, I can help you with the design institute part. If one wants to study the process package, the R&D company should be able to purchase it directly.
This is what the chief engineer from the design institute came to ask me about
He is the chief engineer, so he must have many connections. This requires consulting a professional R&D company
