Abstract:
... Pecan cultivation has increased in recent years. Consequently, the amount of lignocellulosic residuals from its production has expanded. Thus, there is a necessity to explore and add value to their coproducts. The objective of this work was to obtain reducing sugars from pecan biomasses by the optimization of the subcritical water hydrolysis technology in a semi-continuous mode and the physicochem ...

Abstract:
... The inorganic calcium hypophosphite was found to be a cheap, non-toxic, water-soluble and environmentally friendly reducing reagent for radical deiodination in water. Thorough mechanism studies revealed that calcium hypophosphite was oxidized to water insoluble calcium phosphite which was the major co-product of the deiodination reaction. Based on this observation, a practical synthesis of rare d- ...
