Sodium butylnaphthalenesulfonate Use and Manufacturing
Dissolve 426 parts of naphthalene in 478 parts of n-butanol, add 1, 060 parts of concentrated sulfuric acid dropwise with stirring, and then add dropwise 320 parts of oleum. After the addition, the temperature is slowly raised to 50～55℃, and the temperature is kept for 6h. After standing still, the lower layer of acid is released. The upper reaction liquid is neutralized with alkali, and then bleached with sodium hypochlorite, settled, filtered, sprayed, and dried to obtain a finished product.
This product has excellent penetration, wetting, emulsification, diffusion and foaming properties. In acid resistance, alkali resistance, hard water resistance and inorganic salt resistance, adding a small amount of salt can greatly increase the penetration. It is widely used in various processes in the textile printing and dyeing industry, mainly used as a penetrating agent and wetting agent, and can also be used as a detergent, dye aid, dispersant, insecticide and herbicide.
