Application

Diethyl chlorophosphate is a general reagent to synthesize diethylphosphate esters from alcohols, as in the synthesis of organophosphorus nerve agent mimics, chiral phosphine complexes for preparing copper alkoxide phosphine catalysts and the synthesis of chalcogenorhodamine bearing phosphonic acid sensitizers.

The present study investigates the effect of using lignin at nanoscale as new flame-retardant additive for polylactide (PLA). Lignin nanoparticles (LNP) were prepared from Kraft lignin microparticles (LMP) through a dissolution-precipitation process. Both micro and nano lignins were functionalized using
Cu (I)-catalyzed direct enantioselective cross aldol-type reaction of acetonitrile.
