WebCrystal definition, a clear, transparent mineral or glass resembling ice. See more. WebAbstract: In an attempt to explain the co-solvent effect on the shape of β-HMX crystals, molecular dynamics simulations were applied to systematically investigate the interactions of β-HMX crystal faces and the co-solvents (acetone/γ-butyrolactone, dimethylformamide/H 2 O) by varying the volume ratio from 1:3 to 3:1. The growth habit of β-HMX in co-solvent …

WebApr 7, 2024 · If very few crystals are seen, there is likely too much solvent. Return the solution to the heat source and boil off a portion of solvent, then cool again. If all else fails, the solvent can always be removed by rotary evaporation to recover the crude solid. Another crystallization can be attempted, perhaps with a different solvent system. WebOct 2, 2012 · The benefit of using two or three solvents is that it can promote or inhibit the growth of certain crystal faces. Solvent molecules get incorporated into the crystal lattice and adding a second or third solvent means more than one type of solvent molecule can be incorporated into the lattice. This can affect the crystal packing and change the ...
