Specification

The cis-Civetone is an organic compound with the formula C₁₇H₃₀O. The IUPAC name of this chemical is (9Z)-cycloheptadec-9-en-1-one. With the CAS registry number 542-46-1, it is also named as (Z)-9-cycloheptadecen-1-one. The product's classification code is Skin / Eye Irritant. Besides, it should be stored in a ventilated and cool place.

Physical properties about cis-Civetone are: (1)ACD/LogP: 6.48; (2)# of Rule of 5 Violations: 1; (3)ACD/LogD (pH 5.5): 6.48; (4)ACD/LogD (pH 7.4): 6.48; (5)ACD/BCF (pH 5.5): 49384.45; (6)ACD/BCF (pH 7.4): 49384.45; (7)ACD/KOC (pH 5.5): 79662.46; (8)ACD/KOC (pH 7.4): 79662.46; (9)#H bond acceptors: 1; (10)Polar Surface Area: 17.07 Å²; (11)Index of Refraction: 1.448; (12)Molar Refractivity: 78.13 cm³; (13)Molar Volume: 291.3 cm³; (14)Polarizability: 30.97×10^-24cm³; (15)Surface Tension: 28.6 dyne/cm; (16)Density: 0.859 g/cm³; (17)Flash Point: 157.1 °C; (18)Enthalpy of Vaporization: 61.84 kJ/mol; (19)Boiling Point: 371.4 °C at 760 mmHg; (20)Vapour Pressure: 1.04E-05 mmHg at 25°C.

Preparation: the civet liquid caustic soda by 10% KOH-based ethanol, will be the neutral part of the vacuum distillation, collecting 130-170 °C (0.2kPa) fractions, converting them into ammonia urea reduction, separation refining, and then oxalic acid decomposition, may civet ketone. Ketones in the separation of civet civet residue also contains mellow, phthalates can be used to isolate and alkalization, and then use chromic acid oxidation of ketones derived from civet. Synthesis method can be extracted from natural shellac obtained 9,10,16 - trihydroxy-16 acid as raw material, halogenated, elimination of chloride of thionyl chloride, and ethyl acetoacetate condensation, decarboxylation, esterification, iodine cyclization, hydrolysis and other steps to be obtained; It also available from the starting system of oleic acid or 11 to take the goods.

Uses of cis-Civetone: it is used to sulan heart, oriental flavor, citrus Cologne and many floral type, such as large flower jasmine, prynne, narcissus, rose essence and is useful for fixed deodorant. It is indispensable for the preparation of artificial civet spices, the general amount of 1% -2%. It is also used as a substitute for musk. It has a strong ability to be fragrant and often act to deodorant. It can be used for blending high-level essence, in the perfume in the amount of 0.04-0.4% in the balm and lotion in the amount of 0.003-0.02%.
