Organosilicon ethers of ricinoleic acid

Interaction of vinyl trichlorosilane with sodium salt of ricinoleic acid is investigated. It is established that the composition and structure of silicon-containing ethers depends on the content of crystallization water in sodium ricinoleate, and the concentration and nature of solvent. Thus, in the case of a mixture of absolute alcohol with ether and low content of crystallization water, the reaction proceeds by hydroxyl of alcohol to form salt-like compounds containing silicon. In the case of a salt with a high content of crystallization water, the reaction proceeds along two reaction centers with the formation of ether and ester simultaneously. The composition and structure of the obtained compounds were established using elemental analysis, IR, 1H, 13C NMR spectroscopy, and gel chromatography. It is proposed to use prepared organosilicon ethers of ricinoleic acid as additives to motor oils instead of castor oil.
