Is there any difference between the methanol produced from diols and that produced from monols?
There is no difference for methanol products. The process parameters differ: the synthesis pressure for diol is 12.0 MPa, while it is 5.0–6.0 MPa for monol.
The standards applied to the products are the same
Regarding the claim about the 2nd floor, it’s not entirely accurate; there are also methods for synthesizing monohydric alcohols under high pressure, haha! ! ! ! 1. The synthesis reaction of methanol is a volume-reducing reaction; increasing the pressure shifts the reaction in the direction of methanol formation ; From a kinetic perspective, increasing the pressure raises the partial pressures of the reactants, thereby accelerating the reaction ; Furthermore, increasing pressure is also beneficial for suppressing side reactions and improving the quality of methanol. Therefore, increasing pressure is beneficial for the reaction. However, the pressure should not be too high; otherwise, it not only increases power consumption but also raises the requirements for equipment and materials, leading to higher investment costs. This is also relative, of course. 2. The temperature parameters used in production at various plants may also have an impact on the by-products of the crude methanol produced; the synthesis reaction of methanol is a reversible exothermic reaction. From the perspective of chemical equilibrium, as the temperature increases, the value of the methanol equilibrium constant will decrease. However, from the perspective of reaction rate, increasing the reaction temperature speeds up the reaction. Therefore, there is an optimal temperature range. For different catalysts, the operating temperature range varies. The operating temperature for the C307 synthetic methanol catalyst is 190–300 °C, while the optimal temperature is 210–260 °C. The higher the temperature in the methanol synthesis reaction, the more side reactions occur, and the content of organic impurities and other components in the resulting crude methanol increases, which poses difficulties for the subsequent distillation process of the crude methanol. 3. The catalysts used may also differ, which can result in slight variations in the by-products; this all depends on the specific circumstances. 4. However, the same standards apply to both glycol ethers and monohydric alcohols. At the moment, it seems there is no distinction regarding the production of subsequent products. :handshake :handshake
As long as it is distilled, there is no difference; it is all sold **under standard terms.
If it’s all about selling pure alcohols, there should be no difference; it’s just the production processes and control parameters that vary, I guess:lol :handshake
In the end, there is no difference in the methanol product; it’s just that the production processes are different, but they all lead to the same outcome.
The ultimately synthesized pure methanol is the same; what differs are the synthesis process, control methods, investment costs, and economic benefits.
