TRANS-STILBENE C화학적 특성, 용도, 생산
화학적 성질
off-white crystalline powder용도
trans-Stilbene is used in the manufacturing of dye lasers, optical brighteners, non-steroidal synthetic estrogens such as diethylstilbestrol, fosfestrol and dienestrol. It is used as a phosphor and a scintillator. It is also involved in transition metal catalyzed asymmetric epoxidation and dihydroxylation. Further, it is used as raw material in organic synthesis.일반 설명
Off-white crystals. Melting point of 122-124°C. Shows blue fluorescence.공기와 물의 반응
Sensitive to air and light. Insoluble in water.반응 프로필
TRANS-STILBENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.화재위험
Flash point data for TRANS-STILBENE are not available, however TRANS-STILBENE is probably combustible.Purification Methods
Purify it by vacuum distillation. (The final product contains about 1% of the cis isomer.) Crystallise it from EtOH. It has also been purified by zone melting. The styphnate (see next entry) has m 142o. [Lewis et al. J Am Chem Soc 107 203 1985, Bollucci et al.
