Abstract

The invention provides an antifouling agent, which is a natural active compound extracted from rotenone, and has the advantages of high performance, environmental friendliness and good lipophilicity. Its molecular formula is C23H22O6, the molecular weight is 394.42, the structural formula is disclosed in the specification.

Description

technical field [0001] The invention relates to an antifouling agent, in particular to a marine antifouling agent which is a natural active substance rotenone extracted from plants. Background technique [0002] Thousands of attached organisms grow and reproduce in the ocean, and there are more than 100 common species, among which barnacles and mussels are the most important, most representative, and most harmful fouling organisms. Because these marine fouling organisms are attached to the surfaces of ships, floating docks, offshore oil platforms, submarine cables, buoys and mines, cooling pipes of coastal power plants and seawater cages, etc., it increases ship resistance, blocks pipes and nets, Accelerate metal corrosion, increase the weight of offshore facilities, etc., causing huge losses in military activities, marine transportation, industry and aquaculture production. Preventing biofouling has always been the focus of the marine industry. [0003] Since the day when...
