| titleOfInvention | Process for purifying alkyl alcohol ether sulfonate or alkyl phenol ether sulfonate |
| abstract | The invention provides a process for purifying alkyl alcohol ether sulfonate or alkyl phenol ether sulfonate. According to the process, inorganic salt water solution with the mass concentration being 5 to 10 percent is prepared, alkyl alcohol ether sulfonate or alkyl phenol ether sulfonate crude products are added into the inorganic salt water solution, the mass ratio of the alkyl alcohol ether sulfonate or alkyl phenol ether sulfonate crude products to the inorganic salt water solution is 1:(10-50), the materials are stirred at 20 to 95 DEG C so that the alkyl alcohol ether sulfonate or alkyl phenol ether sulfonate crude products are completely dissolved into the inorganic salt water solution to be prepared into raw material water solution, then, ethyl acetate extracting agents are added into the raw material water solution, the volume ratio of the raw material water solution to the ethyl acetate extracting agents is (1-10):1, the ethyl acetate is used for repeated extraction for three times at 20 to 70 DEG C, the upper layer extraction liquid is merged, the inorganic salt water solution is used for carrying out once reextraction on the merged extraction liquid, the obtained lower layer water phase is merged with the extracted raw material water solution, then, the concentration drying is carried out, and the high-purity alkyl alcohol ether sulfonate or alkyl phenol ether sulfonate can be obtained. The process provided by the invention has the advantages that the operation is simple, the cost is low, the safety is high, and the process is applicable to industrialization. |
