Drying agents for organic

Magnesium ethylate is used as a drying agent for organic solvents, as an intermediate for the manufacture of organomagnesium and other organic products, as catalyst in the Tishchenko (85) and other reactions (86—91), in the condensation of esters (92), in alkylation reactions, and in polymeri2ations (84,91).

Specialty Isocyanates. Specialty isocyanates are organic isocyanates having the isocyanate function attached to a carbonyl group or to elements other than carbon. /t-Toluenesulfonyl isocyanate is used as a drying agent for organic solvents. Arenesulfonyl diisocyanates, such as m-phenylenedisulfonyl diisocyanate, are used as monomers for base-soluble polymers. Arenesulfonyl monoisocyanates are used as intermediates for pharmaceuticals and herbicides.

Carbonyl difluoride is more easily hydrolysed than phosgene (see Section 9.10.3.1). Indeed, in the presence of alkali metal carbonates or hydrogencarbonates (to remove HF), COFj has been suggested as a drying agent for organic solvents [1457]. 

CaH2 reacts smoothly with water and is a useful source of hydrogen (one liter per g) it is a convenient drying agent for organic solvents and for gases.52...
