Solution enthalpies, acetic acid formation

In the foregoing calculation of Asin//(1) and Asin//(3), we have used the tabulated values for the standard enthalpies of formation of ethanol and acetic acid aqueous solutions. This looks sensible (after the definitions given in section 2.3), because the standard states of ethanol and acetic acid solutions in water correspond to 1 mol of C2H5OH or CH3COOH in about... 

In other reactions of starch esters, for example, 2,3-di-O-acetylamylose reacted with A-iodosuccinimide in the presence of triphenylphosphine to give 2,3-di-0-acetyl-6-deoxy-6-iodoamylose.2019 The ester bonds are fairly stable to acid-catalyzed hydrolysis. Starch esterified with acetylsalicylic acid administered to dogs did not increase the acetylsalicylic acid level to any significant extent in the animal s blood serum.2020 The slow release of herbicides from their esters with starch was analyzed.2021,2022 Alkaline hydrolysis of starch esters is easier than acid hydrolysis.2023 The enthalpy of starch acetate formation was 143.5kJ/mole, and acetylation decreased the susceptibility of the starch backbone to enzymatic hydrolysis and iodine uptake.2024 The hydrolysis of starch and starch acetate in alkaline solutions obeys second-order kinetics.1988...
