99.5% Concentration Methylal Plant
Request a Quote
Due to the azeotrope from methylal, formaldehyde and water, normal rectification methods do not achieve a high methylal concentration. Based on the original process for normal concentrations, after researching, numerous tests and multiple technical designs, we successfully created a high concentration methylal process, ensuring the methylal purity reaches up to 99.5%.
