Does anyone know about pharmaceutical-grade MTBE? ? The purity must reach 99.99%! Process? Device scale? Processing method? Do you know? ?
What is MTBE and what is it used for?
MTBE, or methyl tert-butyl ether, has a melting point of -109°C and a boiling point of 55.2°C. It is a colorless, transparent liquid with a high octane rating; it possesses an ether-like odor. MTBE is an ideal component for producing lead-free, high-octane oxygenated gasoline, and it is widely used as a gasoline additive around the world. Is the pharmaceutical grade used in medicine? ? ? What’s the point of using gasoline additives with such high specifications?
Methyl tert-butyl ether is currently used as a gasoline additive to increase octane rating. . There is also one used to extract high-purity isobutylene, as a raw material for rubber production
Could you provide a detailed explanation on the purification of isobutylene? I have a project on hand recently, where the client wants to produce isobutylene through butanol cracking
I’m not sure about the specific process either. . MTBE cracking is a reverse reaction that requires a catalyst. It’s hard to say something about the butanol cracking you mentioned. It is a process of dehydration; I’m not exactly sure
There is a small amount available in analytically pure form, used for the analysis of certain anticancer drugs; it is expensive, and its use on a large scale is likely not feasible. The purity level is 6 nines
Could you explain it in more detail? I’d like to learn more, such as the production process or the current market demand and value
When I used to work at Dongguangyang Pharmaceutical Research Institute, I would buy reagent-grade material with a purity of 99.8%, and by using a glass distillation tower – the kind used in laboratories – and performing repeated distillations, it was possible to achieve a purity of 99.999%. Five liters could be distilled at a time.
The market demand for this product is likely not very high, as the price is quite high; I think it was 450 yuan per bottle (4L)
By controlling the content of impurities in the raw materials and the reaction temperature, the process is not very different from that of fuel-grade MTBE.
