Abstract

PROBLEM TO BE SOLVED: To obtain a new compound useful as an antifoulant capable of preventing underwater harmful fouling organisms from adhering without polluting environment. SOLUTION: This compound shown by formula I or II can be produced not only by chemical synthesis but also from extracts of animals, plants and microorganisms containing the compound. As an organism containing the compound, Lemnalia africana may be exemplarily presented. The compounds of formulas I and II can be utilized as an antifoulant by preparing coatings, solutions, emulsions, etc., each using the compound. When used as a coating, the compound is blended with a coating composition so as to prepare an antifouling coating to be applied to the bottoms of ships, underwater structure, water channels for cooling water, etc. The blended amount of the compound is preferably 100 ppm to 5%, more preferably 500 ppm to 1% based on the coating weight.

2. Description of the Related Art Barges, mussels, oysters, bryozoans, hydra, sea squirts, etc. are in contact with seawater such as underwater structures such as the bottom of ships, cooling water intake channels such as thermal power plants, and stationary fishing nets. Harmful underwater creatures such as seaweed, seaweed and seaweed attach and breed. Such attached organisms cause enormous industrial damage such as an increase in fluid resistance, heat exchange, a decrease in heat transfer performance, and deterioration of tide of fishing nets. Conventionally, various antifouling agents have been used in order to prevent the adhesion and propagation of such harmful inhabitants living in seawater and freshwater. Such an antifouling agent contains a heavy metal such as an organotin compound, cuprous oxide, or a nitrogen-sulfur compound, or a harmful substance.

SUMMARY OF THE INVENTION Heavy metals and harmful substances
In addition to polluting the environment of rivers and the like, as well as directly harming the human body through fish and shellfish, the use of these substances has become a social problem in recent years. Many antifouling agents are subject to regulation from this point of view. Therefore, development of a safe and effective antifouling agent that replaces these conventional antifouling agents is strongly desired. The present invention has been made to meet such a demand, and an object of the present invention is to provide a novel antifouling agent having sufficient antifouling activity and not polluting the environment.

One liter of acetone was added and left overnight. The acetone containing the extract from the sea squirrel was filtered, and the acetone was distilled off under reduced pressure to obtain an extract. In this first extraction, extraction was performed with acetone containing a large amount of seawater generated at the time of thawing, so 3 liters of acetone was again added to sea stalk after the first extraction, and the mixture was left for 24 hours. Was performed to obtain a second extracted extract. This operation was repeated once again to obtain a third extract,
These were combined. Ethyl acetate was added to the thus-obtained acetone-extracted extract, and after sufficiently extracting soluble components, ethyl acetate was distilled off under reduced pressure to obtain an ethyl acetate-extracted extract. Further, normal hexane was added to the ethyl acetate extract, and the mixture was sufficiently shaken with a separatory funnel, and then a lower layer of hexane poorly soluble matter (6.7 g) was collected. The hardly soluble hexane was developed with chloroform-methanol (5 to 50%) using an open column of silica gel, and fractionated into 10 fractions. The thus obtained fifth fraction was applied to a silica gel preparative thin-layer chromatograph (PLC, 2 mm thick), and repeated with a benzene-ethyl acetate (20%) mixed solvent.
It was developed ten times to scrape off two adjacent components with UV absorption. Compound (I) was slightly tailed, and compound (II) was fairly tailed. Cerium sulfate (1

The mussel has one foot which can be extended to the same length as its own body, and a thread is formed in a groove running longitudinally through this foot. The tip of this thread is made of an extremely strong protein, and the mussel is attached to the bottom of the ship by about 20 to several tens of thread. It is thought that the tip of this foot has a sensory organ for judging and selecting a suitable base for attachment. When the tip of the mussel is brought into contact with a substance having an adhesive repellent activity such as copper sulfate at its tip, it contracts as if shrinking. The foot stimulation method is a method for evaluating the adhesion repellent activity of various substances on mussels based on this phenomenon. It is clear from the literature that this method is very effective.
