On the basis of that expenence, the process was abandoned in 1982 in favor of the current incineration technology. Major considerations were the large residue of hydrolysis products and problems encountered in scaling up the mixing of GB with aqueous NaOH solution (Flamm et al., 1987; Coale and DePew, 1992~.

From page 113... ...
The products from reaction of GB with aqueous NaOH are only slightly hazardous and are suitable for shipment, storage, or further processing. They watt contain some of the mentioned diester, a substance not very hazardous itself and a contaminant in stockpiled GB, but convertible to GB on reaction with hydrochloric acid (HF)

From page 114... ...
The general cIass of processes described here appears to be broadly applicable to agent destruction. A disadvantage common to these processes is the relatively large quantity of organic waste produced.

. Additional laboratory work should be conducted to determine rate constants for diester hydrolysis and the second stage of GB hydrolysis, to allow comparison with the rate constant for reaction with NaOH and to form a basis for pilot plant work if this alternative is to be pursued.
