For this purpose, systematic studies were made of the enthalpies of neutralization of HCl, HBr, HNO 3 , acetic, proprionic, and butyric acids with NaOH, enthalpies of hydrolysis of methyl and ethyl acetate with NaOH, and the reaction rates of the ester hydrolysis with NaOH. The general ...
The diethyl ether was then evaporated to leave a residual liquid, Y.Y was subjected to a reaction using excess concentrated H2SO4 at 180 C and a final product mixture was obtained.HO O.CH3H2C NaOH diethyl ether conc. H2SO4O - C -CH3Y evaporate H3 C - C -CH3占What is the number...
Propose a mechanism for the reaction of benzoyl chloride with acetic acid, and show the structure of the resulting anhydride. Draw the major organic product from the reaction of 2-(carboxymethyl)benzoic acid with acetic anhydride and heat. Can some...
Methylation of 3-ethyl-phenol gave 3-ethylanisole which was treated with NBS at room temperature for 8 h to providing intermediate 246. A sequence involving formation of the lithium salt, reaction with tri-n-butyl borate and hydrolysis afforded (2-ethyl-4-methoxy)phenylboronic acid (247)...
They prepared an itaconic acid-based epoxy resin (EIA), which was cross-linked with phytic acid (PA) to form phosphate-based adaptable networks (Fig. 3 – route 1), using PA-cured bisphenol A epoxy as control sample [47]. EIA was synthesized through the reaction between bioresource ...
an ester and hydrochloric acid. To neutralize the resulting acid, a small amount of pyridine can be added to the reaction mixture. Alcohols reacting with acid anhydrides also yields an ester. But unlike the reaction involving carboxylic acid, these two reactions don't give an equilibrium mixture...

All the Et20- insoluble materials were dissolved in HCONMe2 (8 cm3) and subjected to a condensation reaction with VIII. N -t-Butyloxycarbonyl- ( D-leucyl-L-glutamyl-L- histidyl)2 Methyl Ester Trihydrate [Boc-(o-Leu-L- Glu-L-His)2-0Me·3H20] (X). A solution of VIII (1.1 g, ...
This surfactant is made using methyl esther from coconut oil through hydrogenation of methyl esther (methyl laurate) by using metal catalyst, sulfatation reaction by adding H2SO4, and neutralizationby using NaOH. The goal of this research is to obtain the optimum reaction condition in aspects of...
PURPOSE:To obtain the titled substance useful as a synthetic raw material for perfume substances in high purity, by condensing methyl oxide with an acetic ester in the presence of a concentrated sulfuric acid catalyst, bringing the reaction product into contact with water at a high temperature, an...
