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.
Description of Cellulose diacetate : According to the degree of substitution(DS), Cellulose acetate can be commonly classified to cellulose diacetate(DAC) and cellulose triacetate(TAC). Usually, DAC has DS with 2.2-2.5 while TAC has DS with above 2.7.(DS is an average number, It represents the number of -OH which is substituted by -C0CH3) Usage of Cellulose diacetate : It can be used to make non-woven fabrics for cigarette filters, ink pen refills, water absorbing layers and masks for diapers. Other serise of Cellulose diacetate : Plastic grade Cellulose diacetate . WE ALSO HAVE CELLULOSE TRIACETATE CAS No.: 9012-09-3 Product Parameters Item /Results Moisture % :1.9 Free acid %: 0.003 Combined acid %: 55.4 Percolate Value g/m2 :43 Viscosity mpa.s : 123 Yellowness b : 3.98 Bulk density g/m3 : 0.2544 Conclusion The product quality conforms with the enterprise standard
