Functional properties were investigated on chickpea proteins acetylated at 6 and 49% of the -amino groups of lysine. In water and in 0.25M NaCl solutions, acetylated chickpea proteins (ACP) were more soluble at high pH (pH>8), but less soluble at low pH (pH 2–7), than native chick...

Cl– ) and carboxylates (RCO2– ) are much weaker bases, and thus much better leaving groups than HO–. So by adding an amine to an acyl halide or acid anhydride, nucleophilic acyl substitution can occur under much milder conditions, resulting in our desired amide. (One can obtain amides...

Glacial acetic acid (16 mL), acetic anhydride (100 mL), and copper nitrate trihydrate (1.0 g, 4.26 mmol) were added to a solution of 5,10,15,20-tetraphenylporphyrin (1.0 g, 1.63 mmol) in CHCl3(500 mL). The reaction mixture was stirred at r.t. for 16 h, cooled, and water (200...
The invention provides a process that includes a first step of reacting the hydroxyl groups of a acrylic resin having hydroxyl groups and carbamate groups with a compound that converts the hydroxyl gr
