The IUPAC name of this chemical is Butyric acid. With the CAS registry number 107-92-6 and EINECS registry number 203-532-3, it is also named as ethylacetic acid. In addition, the molecular formula is C4H8O2. It is an oily colorless liquid that is easily soluble in water, ethanol, and ether, and can be separated from an aqueous phase by saturation with salts such as calcium chloride. And it has an unpleasant smell and acrid taste. Besides, it is found in butter, parmesan cheese, vomit, and as a product of anaerobic fermentation (including in the colon and as body odor).
Physical properties about this chemical are: (1)ACD/LogP: 0.70; (2)# of Rule of 5 Violations: 0; (3)ACD/BCF (pH 5.5): 1; (4)ACD/BCF (pH 7.4): 1; (5)ACD/KOC (pH 5.5): 8.756; (6)ACD/KOC (pH 7.4): 1; (7)#H bond acceptors: 2; (8)#H bond donors: 1; (9)#Freely Rotating Bonds: 2; (10)Polar Surface Area: 37.3 Å2; (11)Index of Refraction: 1.411; (12)Molar Refractivity: 22.145 cm3; (13)Molar Volume: 89.188 cm3; (14)Polarizability: 8.779 ×10-24cm3; (15)Surface Tension: 32.584 dyne/cm; (16)Density: 0.988 g/cm3; (17)Flash Point: 69.712 °C; (18)Enthalpy of Vaporization: 42.395 kJ/mol; (19)Boiling Point: 164.348 °C at 760 mmHg; (20)Vapour Pressure: 1.351 mmHg at 25°C.
Preparation of Butyric acid: It is industrially prepared by the fermentation of sugar or starch, brought about by the addition of putrefying cheese, with calcium carbonate added to neutralize the acids formed in the process. In addition, it can be prepared by butan-1-ol. The other product is butyraldehyde. This reaction will need reagent NaBrO3 and catalyst Ru2(dmnapy)Cl4. The reaction time is 15 hours with ambient temperature. The yield is about 91.5%.
Uses of Butyric acid: it can be used as food, perfume and fishing bait additives, an animal feed supplement, an approved food flavouring. In addition, it is used in the preparation of various butyrate esters. Besides, it can react with 4-methyl-quinoline to get 4-methyl-2-propyl-quinoline. This reaction will need reagents sulfuric acid and iron(III) sulfate, and solvent H2O. The reaction time is 20 hours with irradiation. The yield is about 76%.
