Is decanoic acid a weak acid?
Medium-chain fatty acids, e.g. octanoic and decanoic acids, are variously described as acting either like uncouplers [l] or as weak-acid preservatives [2].

Is capric acid the same as decanoic acid?
Capric acid, also known as decanoic acid or decylic acid, is a saturated fatty acid. Its formula is CH3(CH2)8COOH.
Is decanoic acid water soluble?
The water solubility at 35°C and at 50°C is not measurable. The dissociation constant of Decanoic acid in water is extrapolated to be in the range from 4.89 to 5.03. The solubility of Decanoic acid is >1kg/L Hexane at 22°C in g/L at > 1kg/L Ethanol 22°C.
Is decanoic acid soluble or insoluble in?
Decanoic acid (sodium salt) is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF). The solubility of decanoic acid (sodium salt) in ethanol is approximately 30 mg/ml and approximately 5 mg/ml in DMSO and DMF.
What is the main intermolecular forces of decanoic acid?
Answer: Decanoic acid has one more methylene group than nonanoic acid, so it has stronger van der Waals attractive forces than nonanoic acid and a higher boiling point. Explain why the boiling point of 2,2-dimethylpropanoic acid (164 °C) is lower than that of pentanoic acid (186 °C).
Is decanoic acid a carboxylic acid?
The first solid aliphatic carboxylic acid is decanoic acid, which has a melting point of 31.5°C. An unsaturation in the principal chain lowers the melting point temperature considerably.
What is the percent composition of decanoic acid?
Decanoic acid, natural, >=98%, FCC, FG.
What is decanoic acid soluble in?
The solubility of Decanoic acid is >1kg/L Hexane at 22°C in g/L at > 1kg/L Ethanol 22°C. The active substance as manufactured does not include any organic solvent. The calculated partition coefficient octanol-water is 4.02 for the undissociated acid.
What kind of molecule is decanoic acid?
Structure for FDB012027 (Decanoic acid) Belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms.
How many carbon atoms are in decanoic acid?
How do salcaprozate sodium and sodium caprate enhance intestinal permeation?
Abstract Salcaprozate sodium (SNAC) and sodium caprate (C10) are two of the most advanced intestinal permeation enhancers (PEs) that have been tested in clinical trials for oral delivery of macromolecules. Their effects on intestinal epithelia were studied for over 30 years, yet there is still debate over their mechanisms of action.
What is sodium caprate (C 10)?
The medium chain fatty acid (MCFA) promoter, sodium caprate (C 10 ), is both a food additive and a component of a rectal suppository originally marketed in Sweden (Doktacillin®, Meda, Solna, formerly marketed by AstraZeneca, Södertälje [22]) and in Japan (Kyoto Pharmaceutical Industries, Ltd, Kyoto [23] ).
What is the pKa of LiTMP?

What is the name of the salt in MCFA?
C 10 C 10 is the sodium salt of the aliphatic saturated 10-carbon MCFA, capric acid, also known as sodium decanoate (or the sodium salt of decanoic acid). Capric acid is present in dairy products, particularly milk, where it constitutes a significant proportion of the fatty acid content.
