(Z)-1,2-디페닐에텐 C화학적 특성, 용도, 생산
화학적 성질
pale yellow liquid
용도
cis-Stilbene: stilbene and its natural derivatives such as resveratrol and vitisins inhibits Staphylococcus aureus hemolytic activity and biofilm formation without affecting its bacterial growth
일반 설명
Oily yellow liquid. Freezing point 5°C. Insoluble in water. Soluble in ethanol. Unstable relative to the trans isomer, which is a solid with a melting point of 122-124°C.
공기와 물의 반응
Sensitive to prolonged exposure to air and light [Lancaster]. Insoluble in water.
반응 프로필
CIS-STILBENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.
화재위험
Flash point data for CIS-STILBENE are not available, however CIS-STILBENE is probably combustible.
Purification Methods
Purify it by chromatography on alumina using hexane and distil it under vacuum. (The final product contains ca 0.1% of the trans-isomer.) [Lewis et al. J Am Chem Soc 107 203 1985, Saltiel J Phys Chem 91 2755 1987, Beilstein 5 H 630.]
