The phrase "acetate flash" is correct and usable in written English.
It can be used in contexts related to photography, film, or materials that involve acetate and a sudden burst of light or color.
Example: "The artist used an acetate flash technique to create vibrant overlays in her mixed media artwork."
Alternatives: "acetate burst" or "acetate illumination".
Cellulose acetate butyrate (CAB) was flash-pyrolyzed at 600 1000°C/s to temperatures in the 460 600°C range under 1 atm Ar.
The product was purified by flash chromatography (1 1 hexane/ethyl acetate, 100% ethyl acetate) to yield the coupled product as a pure white solid, (50 mg, 0.06 mmol, 36%) (1 1 ratio of diastereomers a and b).
The purification through flash chromatography (ethyl acetate:hexane) afforded the yellow oil product.
The mixture was evaporated to dryness and purified by flash chromatography (ethyl acetate).
The crude product was purified by flash chromatography (ethyl acetate) to give 3, a NOTA derivative, as a white solid (0.26 g, 0.10 mmol, 67%).
The crystals were soaked in cryo-protectant solution composed of 35% (w/v) poly ethylene glycol) 4000, 2 or 20 mM A/S, 50 mM myo-inositol, and 100 mM sodium acetate buffer (pH 4.6) and flash-frozen in a nitrogen stream at 100 K.
The crude product was purified with flash chromatography (Ethyl acetate-DCM gradient elution) to give the target acetamide or carboxamide.
Transdermal estrogen 48 or megestrol acetate 49 can improve hot flashes, but are associated with gynecomastia and breast/nipple pain and sometimes also weight gain.
After stirring at ambient temperature for another 2 h, the mixture was filtered and evaporation of the solvent gave a residue that was purified by flash chromatography (ethyl acetate-DCM gradient elution) to give the desired carboxamide derivatives.
The flash chromatography (7 3 hexane/ethyl acetate) furnished the compound 3,4-bis(benzyloxy phenol 3 as solid (0.77 g, 80%% yield).
