The cyanoethylation and infrared spectra of some ricinoleic acid derivatives

摘要: Five ricinoleic acid derivatives have been cyanoethylated with acrylonitrile, namely, 4-ricinoleoylmorpholine, 4-ricinelaidoylmorpholine, 4-(12-hydroxystearoyl) morpholine, 1,12-dihydroxy-9-octadecene and 1,12-dihydroxyoctadecane, using benzyltrimethylammonium hydroxide as a cyanoethylation catalyst water to retard the polymerization of acrylonitrile. Any polyacrylonitrile formed was readily precipitated out an ethereal solution. Purification products accomplished by washing catalyst, rapid distillation under high vacuum, crystallizations from methanol. In addition, 1,12-bis(β-cyanoethoxy)-9-octadecene isomerized fromcis totrans form crystallized successively acetone The infrared spectra these compounds determined. It found that characteristic absorption for nitrile group at 4.44 microns is about 67% greater in chloroform than carbon tetrachloride it obeys Beer's law over wide range concentrations, thus permitting convenient analysis this type compound. Some properties are described.
