EC number: 203-466-5 | CAS number: 107-13-1, The solubility of acrylonitrile in water is reported to be 7.3% wt, at 20 oC. Interpretation of results: acrylonitrile is very soluble (> 10000 mg/L). SUMMARY. Measurement and correlation of isobaric vapour-liquid equilibrium for the (acetonitrile + water) system containing different ionic liquids at atmospheric pressure. Acetonitrile is completely miscible with water, and its high dielectric constant and dipole moment (Table 2.1) make it a suitable solvent for many inorganic and organic compounds. The method can be implemented in a single step, or the glycerol can be previously submitted to a dehydration step. 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. 166 0 obj<> endobj <]>> 6. The principal pathway leading to the degradation of acrylonitrile in air is photooxidation, mainly by reaction with hydroxyl radicals (OH). Dielectric constants: 5.5 (1 kHz, 25 °C), 4.2 (1 MHz, 25 °C).Can behave as branched as well as linear polymer. Interpretation of results: acrylonitrile is very soluble (> 10000 mg/L). 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). It dissolves when mixed with water. Acrylonitrile is a monomer widely used in industry for manufacture of plastics, rubber, nylon, and acrylic fibers1.
