Specification
trans-Cinnamic acid is a white crystalline organic acid, which is slightly soluble in water. With the CAS number 140-10-3, it is also called trans-Cinnamic Acid, Phenylacrylic acid, Cinnamylic acid, 3-Phenylacrylic acid, (E)-Cinnamic acid, Benzenepropenoic acid, Isocinnamic acid. It is obtained from oil of cinnamon, or from balsams such as storax.
Physical properties about trans-Cinnamic acid are: (1)ACD/LogP: 2.412; (2)ACD/LogD (pH 5.5): 1.22; (3)ACD/LogD (pH 7.4): -0.57; (4)ACD/BCF (pH 5.5): 2.60 ; (5)ACD/BCF (pH 7.4): 1.00; (6)ACD/KOC (pH 5.5): 31.72; (7)ACD/KOC (pH 7.4): 1.00; (8)#H bond acceptors: 2; (9)#H bond donors: 1; (10)#Freely Rotating Bonds: 2; (11)Index of Refraction: 1.616; (12)Molar Refractivity: 43.707 cm3; (13)Molar Volume: 125.035 cm3; (14)Polarizability: 17.327 10-24cm3; (15)Surface Tension: 49.7249984741211 dyne/cm; (16)Density: 1.185 g/cm3; (17)Flash Point: 189.53 °C ; (18)Enthalpy of Vaporization: 53.129 kJ/mol; (19)Boiling Point: 264.999 °C at 760 mmHg; (20)Vapour Pressure: 0.00499999988824129 mmHg at 25°C
Uses of trans-Cinnamic acid: This is a fragrant acid occurring in aromatic resins. Cinnamic acid and its derivatives are used as important components in flavours, perfumes, synthetic and pharmaceuticals, though its primary use is in the manufacturing of the methyl, ethyl, and benzyl esters for the perfume industry.
When you are using this chemical, please be cautious about it as the following:
1. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
2. Wear suitable protective clothing;
3. Wear suitable gloves and eye/face protection;
