Production Method of Sodium 4-methylbenzenesulfonate
A BHT production neutralization wastewater, in which the content of sodium p-toluenesulfonate is 19.8%, and the content of alkali neutralizing agent (alkali containing sodium ions) is 3.7%. The specific steps of producing sodium p-toluenesulfonate using the neutralized wastewater include: adding an appropriate amount of pH regulator (p-toluenesulfonic acid) to a pH regulating kettle to adjust the pH value of the neutralized wastewater to 6-7, then pumping it into a decolorization kettle, adding activated carbon to the decolorization kettle and heating it up to 80-90 ℃, stirring for 1 hour for decolorization, pumping it into a filter press to filter out the activated carbon, and the liquid enters an evaporative concentration kettle. It is heated and evaporated at atmospheric pressure to 120-125 ℃, Enter the slicer to cool the slices and obtain the product sodium p-toluenesulfonate. The evaporated water vapor is condensed and recycled for the preparation of alkaline neutralizing agent water. The appearance of the product is a white sheet-like solid. After sampling and analysis, the content of sodium p-toluenesulfonate is 89.4%, which can meet the refined grade standard and meet market quality requirements.

Q: What are the physical properties of sodium p-toluene sulfonate?
A: White or light yellow crystal or powder, the exact form depends on the purity. The melting point is about 200-220°C. The boiling point is higher, usually above 300°C. The solubility: easily soluble in water. Easily soluble in water, slightly soluble in organic solvents, such as ethanol and acetone. Density about 1.3 g/cm³ (20°C), depending on the molecular structure. Stable at room temperature, but may decompose at high temperatures or under conditions of strong acids and bases.
Q: What safety precautions should be taken when using sodium p-toluenesulfonate?
A: Wear appropriate protective gloves, glasses and mask to avoid direct contact with skin and eyes. Operate under well ventilated conditions and avoid inhaling its dust or vapour. Store in a cool, dry and ventilated place, away from fire and heat sources. In case of inadvertent contact with skin or eyes, flush immediately with plenty of water and seek medical help. Dispose of waste properly in accordance with local regulations to avoid pollution of the environment.
Q: What is the synthesis method of sodium p-toluenesulfonate?
A: Prepare raw materials such as p-toluenesulfonic acid and sodium hydroxide. Neutralisation reaction of p-toluenesulfonic acid and sodium hydroxide in a suitable solvent to produce sodium p-toluenesulfonate and water. The unreacted raw materials and by-products are removed by filtration, washing and drying to obtain the final product. As required, the product can be further purified by methods such as recrystallisation or column chromatography to improve its purity and quality.
