Copolymerized formaldehyde reactant ratio
Thread Content
This post was last edited by zhihuzheye on 2010-10-26 08:28. In the production of copolymerized polyoxymethylene, what is the ratio in which formaldehyde (60%) and ethylene glycol should be added? What is the ratio of TOX to DOX during polymerization? What phenomena would occur if the proportions are out of balance? I would appreciate it if experts could share their experience.
Is the issue sensitive, or is there currently no mature technical expertise in the country?
The reaction between formaldehyde and ethylene glycol should be in a 1:1 ratio, but the concentration of the formaldehyde solution is not necessarily constant; therefore, it is necessary to make rough adjustments based on the formaldehyde concentration. From a production perspective, it is recommended to use a slight excess of formaldehyde.
