| titleOfInvention | Method for obtaining dispersing agent for detergent - amphat |
| abstract | The invention relates to sulfo-containing substances, in particular the preparation of a detergent dispersant. The goal is to increase the dispersing ability and resistance to salts of the rigidity of the target product. The process is carried out by sulfonating olefins with a boilout of 180-240 ° C with sulfur trioxide vapors diluted with air at 35-40 ° C, followed by treatment first with sodium ethoxide to a neutral environment and then with ethanolamines maintaining the molar ratio of olefin and ethanolamine 1 :( 0.4-0.6) at 120-140 ° C for 20-50 minutes. These conditions provide in the resulting product a dispersing ability better than the known product (0.15-0.6 g g of surfactant / 100 g sodium oleate), and better resistance to salts of rigidity |
