Is ethyl 4-Aminobenzoate soluble in water?
Is Ethyl 4-aminobenzoate hydrochloride soluble in water? Ethyl 4-aminobenzoate was found to be insoluble in water and 1.0 M NaOH, but upon addition of 6.0 M NaOH to this solution, ethyl 4-aminobenzoate became insoluble.
What solvents is benzocaine soluble in?
QUICK LINKS. Benzocaine is a surface anesthetic that reversibly inactivates voltage-dependent sodium channels. Solubility : Soluble in water (0.4 mg/ml at 20° C), methanol, chloroform (500 mg/ml), ethanol (50 mg/ml), and ether (250 mg/ml).
Is ethyl 4 Aminobenzoate polar or nonpolar?
The ethyl-4-aminobenzoate is similar to benzoic acid, in that it has a nonpolar ring and has polar attachments. The nonpolar ring is what makes it soluble in diethyl ether.
What does ethyl 4 Aminobenzoate look like?
Ethyl 4-aminobenzoate – Trait This product is white crystalline powder; Odorless; Light color gradient yellow. This product is soluble in ethanol, chloroform or ether, slightly soluble in fatty oil, and slightly soluble in water.
Is ethyl 4 Aminobenzoate toxic?
May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. May be harmful if absorbed through the skin. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed.
Is benzocaine soluble in acetone?
The mole fraction solubility of benzocaine decreases in the order: 1,4-dioxane, acetone, ethyl acetate, chloroform, acetonitrile, methanol, n-butanol and toluene.
How do you dissolve benzocaine?
It is very slightly soluble in water (1 in 2,500) and freely soluble in alcohol (1 in 5-8) and ether (1 in 4). Benzocaine is sparingly soluble in almond and olive oil (1 in 30-50), and it will dissolve in dilute acids. It should be protected from light and stored in tight containers.
How do you make benzocaine water soluble?
Benzocaine occurs in two forms: a crystalline salt (benzocaine HCl) that is soluble in water at 0.4 g/L, and a nonwater-soluble basic form that must be dissolved in ethyl alcohol at a concentration of 0.2 g/ml before it is sufficiently soluble in water to create a functional induction dose.
Why is ethyl 4 Aminobenzoate polar?
The three solids, Benzoic acid, Ethyl 4-aminobenzoate, and 9-Fluorenone were all soluble in polar diethyl ether because they have similar polarities. Diethyl ether has an uneven distribution of electrons spread across the molecule, making it slightly polar.

Is ethyl p aminobenzoate polar?
Is 4-Aminobenzoate an acid or base?
4-aminobenzoate is an aromatic amino-acid anion that is the conjugate base of 4-aminobenzoic acid. It has a role as an Escherichia coli metabolite, a plant metabolite and a Saccharomyces cerevisiae metabolite. It is an aromatic amino-acid anion and an aminobenzoate.
Is fluorene soluble in diethyl ether?
Diethyl ether is the best solvent for dissolving the mixture, because though it is a polar molecule, its ethyl groups make it a nonpolar solvent. The compounds, fluorene and 1, 4-dibromobenzene, are also nonpolar; therefore, it would be easier for it to be dissolved in this organic solvent.
Is PABA water soluble?
The solubility of PABA is 6.1 g/l at 30oC in water, 125 g/l alcohol and 17 g/l ether. PABA is soluble in ethyl acetate and glacial acetic acid, slightly soluble in benzene, and practically insoluble in petroleum ether. PABA is known as a sunscreen agent in cosmetics.
What is fluorene soluble in?
Fluorene tends to be readily soluble in non-polar organic solvents like toluene, dichloromethane, chloroform, benzene, and carbon tetrachloride. Since water is polar, we would expect fluorene to be insoluble in water, which is actually the case.
