This information has not been reviewed or verified by the Agency or any other authority. In terms of its molecular structure, it consists of a vinyl group linked to a nitrile. The total solubility parameter is the geometric mean of the three components d D (from non-polar, or dispersion interactions), d P (from polar attraction), and d H (from hydrogen bonding). The method can be implemented in a single step, or the glycerol can be previously submitted to a dehydration step. The solubility of acrylonitrile in water is reported to be 7.3% wt (73 g/L) at 20 oC. 0 It is partially soluble in water, soluble in most organic solvents (including ethyl alcohol, acetone, benzene, carbon tetrachloride and ethyl acetate), very reactive and polymerises violently in the presence of alkalis or peroxides. Nitrile rubbers, the original driving force behind acrylonitrile production, have taken a less significant place as end-use products. Executive summary: 0000002570 00000 n Acrylonitrile is both readily volatile in air and highly soluble in water. 3.

Acrylonitrile is a volatile, highly reactive, colourless liquid. Satisfactory agreement has been obtained between theory and experimental data. It was found that the copolymer composition produced in the suspension polymerization of acrylonitrile and styrene was significantly different from that in the bulk polymerization at the same monomer feed ratio, since acrylonitrile is partially soluble in water. Acrylonitrile is a fumigant insecticide that is not approved for use within the EU and is now considered obsolete. The comparative study of the thermodynamic solubility of PAN in five solvents led to the following conclusions: the thermodynamic solubility of PAN, characterized by the experimental and calculated cloud point curves, differ significantly for two kinds of solvents: organic aprotic and inorganic aqueous solution of NaSCN; the solubility of PAN in an aqueous solution of NaSCN is much higher … The acrylonitrile repeating unit of the polymer has the following structure: . Bioaccumulation of acrylonitrile is not anticipated, given experimentally-derived values of 0-0.3 for the log Kow, and a bioconcentration factor (BCF) of 1.0 has been calculated from the known water solubility of acrylonitrile. The solubility of acrylonitrile in water is reported to be 7.3% wt, at 20 oC. It has a high potential for leaching to groundwater. This site is not fully supported in Internet Explorer 7 (and earlier versions). Acrylonitrile (CH2= CH − C ≡ N) is a volatile, flammable, colourless liquid with a characteristic odour. Acrylonitrile is soluble in water and most common organic solvents such as acetone, benzene, carbon tetrachloride, ethyl acetate, and toluene.
