Use methyl naphthalene to produce water reducing agent
Methylnaphthalene is produced as a water reducing agent, and appropriate amount of waste acid can be added during sulfonation, and appropriate amount of waste aldehyde solution can be added during condensation reaction, but the reaction temperature should be appropriately increased; during neutralization reaction, appropriate amount of waste solution can be added to adjust pH It is not necessary to filter the CaSO4 precipitate after the value, and make it directly into the finished product.
