2018 Sep 4. The E (trans) isomer of cinnamic acid. Faculty of Engineering 5. Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4 to 673 K). It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. impure particles in the compound are excluded from the crystal lattice. Premium Antimicrobial activity of trans-cinnamic acid and commonly used antibiotics against important fish pathogens and nonpathogenic isolates.
