Dissolve 426 parts of naphthalene in 478 parts of n-butanol, add 1060 parts of concentrated sulfuric acid dropwise while stirring, and then add 320 parts of fuming sulfuric acid dropwise. After adding, slowly raise the temperature to 50-55 ℃ and keep it warm for 6 hours. After standing still, release the lower layer of acid. The upper reaction liquid is neutralized with alkali, bleached with sodium hypochlorite, settled, filtered, spray and dried to obtain the finished product.

pull powder BX
The scientific name of BX is sodium butyl naphthalene sulfonate, and the structural formula is very inconsistent. There are both sodium n-butyl naphthalene sulfonate and sodium isobutyl naphthalene sulfonate. There are two industrial production methods for pulling powder BX: ① Naphthalene is sulfonated with sulfuric acid of the same weight to generate α-naphthalene sulfonic acid. Concentrated sulfuric acid and n-butanol are added at the same time under vigorous stirring, and separated, neutralized and evaporated. (2) Naphthalene is mixed with n-butanol, concentrated sulfuric acid is added, neutralized and dried as the finished product. This product is white and light yellow powder, easily soluble in water. It is stable in hard water, salt, acid and weak lye, and is white precipitated in concentrated caustic soda, which can be dissolved again after being diluted with water. This product is anionic, with water content not exceeding 2%, iron content not exceeding 0.01%, and pH value of 1% aqueous solution 7~8.5. In addition to strong permeability, it also has emulsification, diffusion and foaming properties, poor cleaning ability and poor suspension force to dust.
this product can be widely used as penetrant in scouring, bleaching and dyeing processes. It can also be used as dye cosolvent, acid dye wool dyeing aid, disperse dye dyeing wool, nylon blended fabric dyeing aid, disperse dye dyeing polyester/cotton blended fabric dyeing aid.
use
1. Used as penetrant in textile printing and dyeing industry. It can also be used as detergent, dye aid, dispersant, wetting agent, insecticide, herbicide and emulsifier in synthetic rubber industry.
2. as a penetrant and wetting agent, it can be used in various processes of textile printing and dyeing industry, such as enzyme desizing, wool carbonization, velvet shrinkage, chlorination and rayon silk treatment. It can also be used as wetting agent in papermaking and lake industry. Adding 10% penetrant BX solution into organic pigment is beneficial to color paste preparation. Used as emulsifier in rubber slurry preparation.
3. the product has excellent permeability, wetting, emulsification, diffusion and foaming properties. In acid resistance, alkali resistance, hard water resistance, inorganic salt resistance, adding a small amount of salt can greatly increase penetration. It is widely used in various processes in the textile printing and dyeing industry. It is mainly used as penetration agent and wetting agent. It can also be used as detergent, dyeing aid, dispersant, pesticide and herbicide.
production method
1, refined naphthalene, butanol and sulfuric acid are condensed by sulfonation. Raw material consumption (kg/t) refined naphthalene 300 n-butanol 300 sec-octanol 45 fuming sulfuric acid 840 sulfuric acid 450 caustic soda 190 non-anhydrous 100
2. dissolve 426 parts of naphthalene in 478 parts of n-butanol, add 1,060 parts of concentrated sulfuric acid dropwise under stirring, and then add 320 parts of fuming sulfuric acid dropwise. After addition, slowly raise the temperature to 50~55 ℃ and keep the temperature for 6 hours. After standing, the underlying acid is released. The upper reaction liquid is neutralized with alkali, and then bleached, settled, filtered, sprayed, and dried with sodium hypochlorite to obtain the finished product.
