Eight samples from each set (A and D) were split into two groups, one incubated in 0.15 M phosphate buffered solution (PBS) and the other in PBS containing 0.1% of the phase transfer catalyst, tricapryl methyl ammonium chloride (Aldrich Aliquot 336) (PBS, catalyzed), both at pH 7.4. The samples were suspended in centrifuge tubes with 10 mL of incubation solution by nylon string and the tubes were placed in a shaker bath at a constant temperature of 37°C. Periodically, the samples were taken out of the tubes, placed on lint free paper towels, allowed to dry for exactly one hour, weighed and placed in fresh incubation media. The total time of the study was 48 weeks (330 days). 

The following carbamoylimidazole, which was prepared from 14C-labeled methyl-ammonium chloride and CDI, was not isolated. It was instead fragmented by heating in vacuo into the isocyanate, which was then reacted with an alcohol to give the labeled carbamate [220]...

This paper is a follow-up of the previous study (Ref 7) whereby the adsorption of the carbon-14-labeled quaternary salt, stearyltri-methyl ammonium bromide (STAB), from soln by HMX was investigated in more detail. A solvent system for STAB, consisting of 90% water and 10% ethanol, yielded improved adsorption isotherms on 10-micron size powdered HMX. The data was shown to be quantitative and reproducible with a std deviation of O.Olmg...

J. Haberman T.C. Castorina, The Surface Chemistry of HMX , PATR 3089 (1963) [A study was made of the solution-adsorption properties of HMX using a 14C labeled quarternary ammonium salt, stearyl tri-methyl ammonium bromide (STAB). The solvent system used consisted of 10% ethanol and 90% w. The solution-adsorption system isotherms for 10-micron HMX were measured. The authors conclude that an H-type Langmuir adsorption isotherm is obtd, the adsorption of STAB on HMX is reversible and therefore physi-...
