As a specific example, ethyl acetate and NaOH react to form sodium acetate and ethanol:. Write an equation for the hydrolysis of methyl benzoate in a potassium hydroxide solution. In basic hydrolysis, the molecule of the base splits the ester linkage. The acid portion of the ester ends up as the salt of the acid in this case, the potassium salt. The alcohol portion of the ester ends up as the free alcohol. Write the equation for the hydrolysis of ethyl propanoate in a sodium hydroxide solution.
Hydrolysis is a most important reaction of esters. Acidic hydrolysis of an ester gives a carboxylic acid and an alcohol. Hard water is an aqueous solution containing magnesium, iron, and calcium ions in the form of minerals. In the presence of metallic cations, soap molecules will interact with the molecules and cause them to fall out of solution, forming a salt precipitate more commonly referred to as soap scum.

Login processing Triglycerides Triglycerides are triester molecules composed of a glycerol backbone that is bound to 3 fatty acids.
Hydrolysis Reaction Triglycerides, like other molecules possessing ester groups, are able to undergo hydrolysis. Saponification During saponification, hydroxide ions attack the carbonyl groups in the three esters of the triglyceride.

HIL and RmL activity in these microemulsions was assayed by spectrophotometric measurement of the initial rate of p-nitophenyl butyrate hydrolysis, and by chromatographic determination of the initial rate of octyl decanoate synthesis from 1-octanol and decanoic acid.
The hydrolytic activity of HIL in microemulsions measured as a function of buffer pH prior to dispersal, followed a sigmoidal profile with the highest activities observed at alkaline pHs.
