Sodium metabisulfite is white or yellow crystalline powder or small crystal, with a strong SO2 odor, soluble in water, the aqueous solution is acidic, when contacted with strong acid, SO2 is released to form corresponding salts, and it is oxidized to Na2S2O6 when placed in the air for a long time. Therefore, the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.

Alias: Cinnamonitrilecistrans; 3-Phenylacrylonitrile; (2E)-3-phenylprop-2-enenitrile; (2Z)-3-phenylprop-2-enenitrile CAS Number: 1885-38-7; 4360-47-8 Molecular Formula: C9H7N Linear Formula C6H5CH=CHCN Molecular Weight 129.16 Purity: 98% Beilstein Registry Number 1209546 EC Number 217-552-5 Appearance: Colorless to yellowish liquid, the aroma is very similar to natural cinnamon, with strong spicy fragrance. Melting point: 18-20°C(lit.) Boiling point: 254-255 °C(lit.) Density : 1.028 g/mL at 25 °C(lit.) Flash Point(C): 113°C refractive index : n20/D 1.601(lit.) Preparation The aqueous solution of hydroxylamine hydrochloride and sodium carbonate was prepared by mixing anhydrous sodium carbonate, hydroxylamine hydrochloride and water. Then the aqueous solution of hydroxylamine hydrochloride and sodium carbonate was added to the solution of cinnamaldehyde and ethanol or methanol, stirred and set it well. Then the reaction mixture was poured into the ice water until the white precipitate was precipitated, the white precipitate was filtered out and washed with water, then the cinnamaldehyde oxime was obtained after drying. Acetic anhydride of 2o 2.5 times (mole ratio) was dripped into cinnamaldehyde oxime, stirred for dehydration and cooled, then vacuum distillation was used to recover acetic anhydride and acetic acid produced by the reaction, and then vacuum distillation was carried out. Cinnamonitrile was obtained by collecting stable fractions at 130C / 2064pa or 151.0 / 5330pa. The method has the advantages of simple operation, low raw material, no pollution and high yield.
