Copper ricinoleate

Copper compounds are used routinely and widely to control freshwater snails that serve as intermediate vectors of schistosomiasis and other diseases that afflict humans (Hasler 1949 NAS 1977 Rowe and Prince 1983 Winger etal. 1984 Al-Sabri etal. 1993). These compounds include copper sulfate, copper pentachlorophenate, copper carbonate, copper-tartaric acid, Paris green (copper arsenite-acetate), copper oxide, copper chloride, copper acetyl acetonate, copper dimethyl dithiocar-bamate, copper ricinoleate, and copper rosinate (Cheng 1979). Also, many species of oyster enemies are controlled by copper sulfate dips. All tested species of marine gastropods, tunicates, echinoderms, and crabs that had been dipped for 5 seconds in a saturated solution of copper sulfate died if held in air for as little as a few seconds to 8 h mussels, however, were resistant (MacKenzie 1961). 

The preparation of methyl 12-ketostearate from methyl ricinoleate has been accompHshed using copper chromite catalyst. The ketostearate can also be prepared from methyl ricinoleate in a two-step process using Raney nickel. The first step is a rapid hydrogenation to methyl 12-hydroxystearate, the hydrogen coming from the catalyst, followed by a slower dehydrogenation to product (50,51).

Iodine dissolves very readily in the non-polar solvent paraffin and its violet color is seen in the uppermost phase. The middle layer consists of castor oil, which is naturally colored light yellow as an ester of ricinoleic acid it can also dissolve small amounts of iodine with the formation of a yellow color. The blue copper sulfate solution forms the lower layer because of its higher density.

Soap, metaiiic n. Any product derived by reacting a fatty acid with a metal. Metallic soaps are widely used as stabilizers for plastics. The fatty acids commonly used are lauric, stearic, ricinoleic, naphthenic, octanoic (2-ethylhexanoic), rosin, and tall oil. Typical metals are aluminum, barium, calcium, cadmium, copper, iron, lead, magnesium, tin, and zinc.
