Butyric anhydride Specification

The Butyric anhydride, with the CAS registry number 106-31-0, is also known as Butanoic anhydride. It belongs to the product categories of Pharmaceutical Intermediates; Organics. Its EINECS registry number is 203-383-4. This chemical's molecular formula is C₈H₁₄O₃ and molecular weight is 158.19. What's more, its IUPAC name is called Butanoyl butanoate. It should be stored in a cool, dry and well-ventilated place. It is a colorless liquid that smells strongly of butyric acid, formed by its reaction with the moisture in the air. It is used for the production of plastics, plasticizers, surfactants and textile auxiliaries. It is also used in food additives, flavorings, varnishes, perfumes, pharmaceuticals and disinfectants. It is used in the synthesis of butyrate ester widely used as perfumes and flavours.

Physical properties about Butyric anhydride are: (1)ACD/LogP: 1.879; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.88; (4)ACD/LogD (pH 7.4): 1.88; (5)ACD/BCF (pH 5.5): 15.78; (6)ACD/BCF (pH 7.4): 15.78; (7)ACD/KOC (pH 5.5): 250.72; (8)ACD/KOC (pH 7.4): 250.72; (9)#H bond acceptors: 3; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 6; (12)Polar Surface Area: 43.37 Å²; (13)Index of Refraction: 1.421; (14)Molar Refractivity: 40.916 cm³; (15)Molar Volume: 161.191 cm³; (16)Polarizability: 16.22×10^-24cm³; (17)Surface Tension: 30.961 dyne/cm; (18)Density: 0.981 g/cm³; (19)Flash Point: 87.778 °C; (20)Enthalpy of Vaporization: 43.448 kJ/mol; (21)Boiling Point: 198.279 °C at 760 mmHg; (22)Vapour Pressure: 0.363 mmHg at 25 °C.

Uses of Butyric anhydride: it is used to produce other chemicals. For example, it can react with 2,5-dimethyl-furan to get 1-(2,5-dimethyl-[3]furyl)-butan-1-one. This reaction needs reagent BF₃·OEt₂. The reaction time is 45 min. The yield is 87 %.

Butyric anhydride can react with 2,5-dimethyl-furan to get 1-(2,5-dimethyl-[3]furyl)-butan-1-one.

When you are dealing with this chemical, you should be very careful. This chemical may destroy living tissue on contact and it reacts violently with water. It may cause burns. Therefore, you should wear suitable protective clothing, gloves and eye/face protection. In case of contacting with eyes, you should rinse immediately with plenty of water and seek medical advice. And in case of accident or if you feel unwell seek medical advice immediately.

You can still convert the following datas into molecular structure:
