Let's start off with acid and then we'll work on to base. Okay? In an acid-catalyzed reaction, notice first of all that I'm using the words acid-catalyzed. Okay? That actually already gives us a hint about the mechanism. Okay? Remember when I said whenever you have an acid-...

However, the removal of aspartic acid side chain is likely to alter the stability of the epoxide group while also simplifying the synthesis by reducing steric hindrance for the key coupling reaction between the peptide scaffold and the epoxide part. Compound 118 has been found inhibiting parasitic ...
Process for curing polyepoxides with the reaction product of h2s and tri or poly functional polyepoxides Other resins which may be included are phenol-aldehyde, urea-aldehyde, furfural resins, polyacetals, carbonate and polyamides.ALSO:Adhesive tapes for metal-metal bonding are prepared by impregnati...

(arylmethyl) phosphite, a tetrahalomethane and a tertiary amine in the presence of an acylation catalyst to protect the phenolic hydroxyl group with a phosphoric ester group, glycosylating the reaction product, reacting the produced 4'- demethylepipodophyllotoxin glycoside 4'-phosphate of formula ...
The carboxylic acid anhydride has at least one intramolecular carboxylic anhydride group. These water insoluble polycaprolactone-epoxide adducts on reaction with an inorganic or organic base produce water soluble, carboxyl modifier polycarprolactone-epoxide oligomer addition reaction products which are ...
become pendant to the polymer chain of the cured reaction product. Alternatively, the introduction of carboxyl groups comprises the steps of (1) diffusing an effective amount of α,β-ethylenically unsaturated carboxylic acid into the cured reaction product and (2) polymerizing the diffused acid....
sup.2.The novel polyadducts can be modified by reaction with aldehydes, ketones, monoepoxide compounds, carboxylic acids, carboxylic acid esters or isocyanates, or by protonation with an acid, and may be used, for example, for the cathodic electrocoating of metallic articles. 展开 ...
