TAILORING AND IMPROVEMENT OF LMH-2.
Abstract
The continuous pyrolsis process for BeH2 was investigated both in tubular and stirred pot reactors. Tubular reactors proved unsatisfactory (maximum product purity 70 wt % BeH2) because of pluggage and ether cleavage problems. Feasibility of continuous pyrolysis was demonstrated in stirred pot reactor units which yielded product with purities to 95.5 wt % BeH2. High purity product requires the use of high alkyl/Bayol 35 feed ratios (>0.1). Physical properties of amorphous BeH2 examined for correlation with propellant processability were - air adsorption, bulk density, particle porosity and surface area, sedimentation volume and viscosity effects. Chemical reactivity was evaluated for predicting compatibility with propellant ingredients. Various post-treatments were found to passinate BeH2 to hydrolysis by boiling water. Attempts also were made to improve the compatibility of crystalline BeH2. BeH2 from this program proved more difficult to process than batch-produced material but it was successfully processed in a new formulation. (Author)
