Description

technical field [0001] The invention belongs to a kind of laundry liquid, is an environment-friendly soap-based concentrated laundry liquid, and belongs to the technical field of light industry chemistry. Background technique [0002] In the 1950s, synthetic detergents were greatly developed, but two environmental problems occurred after large-scale use: biodegradation and eutrophication of water quality. The first biodegradation problem is mainly due to the fact that sodium alkyl sulfonates made from tetrapropylene are not easily biodegradable in water. This problem was solved in the 1960s through the new development of petroleum smelting technology and synthesis technology. Using petroleum as raw material to extract normal linear alkanes and produce linear alkylbenzene sulfonic acid (LAS) was fundamentally solved. biodegradation problem. The eutrophication of water quality is generally believed to be due to the eutrophication of the water body caused by the extensive use...
