Is benzene used in the production of polyoxymethylene?
Thread Content
I would like to ask whether benzene is used in the production of polyoxymethylene? Where else is caustic soda used?
Benzene is used in the preparation of the monomer for polyoxymethylene.
Sodium hydroxide and benzene are used in monomer production, and for extraction
Benzene and NaOH are used to extract TOX, while NaOH is used to extract DOX.
After the reaction with formaldehyde to produce triomethylenetetrahydrofuran, benzene is used for extraction and separation of triomethylenetetrahydrofuran, while NaOH is used to neutralize formic acid, the by-product formed in the reaction.
Benzene is used in the monomer unit to extract reaction by-products. Sodium hydroxide is mainly used for reaction neutralization in wastewater. Just wondering, are the material codes the same across all your companies? Is it still the national standard? For example, in our company, formaldehyde is coded as M, methanol as Z, and formic acid as F. . . . .
