Finally the benzoic acid will be precipitated by adding strong acid to the carboxylate salt solution. Bear in mind that ether is less dense than water, so the extract would be on top. When the reaction starts, the water bath is moved away and ether solution of bromobenzene is added dropwise with that rate, which allows the ether to boil uniformly and not very rapidly all the time. If the reaction doesn't start by itself during several minutes (the ether should become cloudy and boil), the flask is placed on a bath with warm water and heated for some time until the beginning of the reaction. Simultaneously, 1,4-dimethoxybenzene has similar solubility’s with diethyl-ether and remains dissolved in the ether layer throughout the experiment while benzoic ion mostly remains in the aqueous layer. 1.2 × 10−4 Salts are ionic compounds and they are readily soluble in water. The yield is 9 gr (50% from theory). Benzoic acid is recrystallised from hot water. Addition of solid carbon acid is stopped, when the reaction mixture thickens and the flask is covered outside by a layer of frost. Benzoic acid is more soluble in diethyl ether than water. 3. After addition of all bromobenzene the reaction flask is heated on a water bath for 1-1,5 h until the full dissolving of magnesium. When sodium hydroxide dissoved in water is shaken into the either, the benzoic acid forms sodium benzoate which is highly ionized and polar, and more soluble in water than the ether. Diisobutylamine and diethyl ether are soluble because they are both nonpolar. Benzoic acid is more soluble in ether because the benzene ring is nonpolar, aye. . IndiaMART > Common Disease Medicines > Pharmaceutical Medicines > Para Nitro Benzoic Acid. For example, dimethyl ether and ethanol (both having the molecular formula C 2 H 6 O) are completely soluble in water, whereas diethyl ether and 1-butanol (both C 4 H 10 O) are barely soluble in water (8 g/100 mL of water). Phenol is soluble only in the stronger base, 10% NaOH. Bear in mind that ether is less dense than water, so the extract would be on top.
