Nov 02, 2009 · 1. Hydrolysis : Esters are slowly hydrolysed by water at reflux temperatures. The reaction is accelerated by dilute mineral acids (HCl, H 2 SO 4) or alkalies. Hydrolysis of esters by alkalies is also known as saponification. It is very rapid because alkalies act as a catalyst and also react with the acid formed as a product of reaction.

The longest carbon chain containing the OH group has four C atoms, so the parent hydrocarbon is butane. Because the OH group is on the first C atom, it is 1-butanol. There is a methyl group on the second C atom, as well as a Cl atom, so the formal name for this alcohol is 2-chloro-2-methyl-1-butanol.

/The attached reflux condenser allows volatile substances to return to the reaction flask so that no material is lost. Since alkenes are immiscible with concentrated HBr, tetrabutylammonium bromide is used as a phase-transfer catalyst. It forms a complex with HBr and extracts it from the aqueous phase into the organic phase where the alkene is.

Apr 19, 2017 · A major advantage of non-aqueous ion exchange is that more metal ions form anionic complexes with chloride or nitrate ions in organic solvents than in water, which means that more metals can be recovered using an anion exchanger from an organic solution than from an aqueous solution. A typical example is the trivalent rare-earth ions.
