专利号:US-5186864-A 优先权日:1989-10-13 标题:Synthesis of dielectric liquids by improved friedel-crafts condensation 发明人:COMMANDEUR RAYMOND; BERGER NOELLE; JAY PIERRE; KERVENNAL JACQUES 权利人:ATOCHEM 摘要:Dielectric liquids are prepared by (a) Friedel-Crafts condensing at least one aromatic halide with at least one aromatic compound in the presence of a catalytically effective amount of ferric chloride, and thereafter deliberately avoiding any downstream destruction/neutralization and/or washing of such ferric chloride catalyst, (b) optionally, removing unreacted reactants from the medium of reaction, and (c) recovering from such medium of reaction a purified dielectric liquid; the subject process is thus environmentally improved by avoiding the generation of aqueous solutions containing contaminating amounts of objectionable organic compounds.

专利号:US-10024983-B1 优先权日:2015-12-01 标 题 :Metal-loaded plastic scintillators for gamma-ray spectroscopy 发明人:FENG PATRICK L; CORDARO JOSEPH GABRIEL; MENGESHA WONDWOSEN; MYLLENBECK NICOLAS RICHARD 权利人:NAT TECH & ENG SOLUTIONS SANDIA LLC 摘要:Exemplary embodiments of several new metal-loaded plastic scintillators are reported herein, comprising sterically and electronically isolated organotin additive complexes. Distance-dependent quenching relationships have been used as design criteria for the selection and synthesis of these organometallic additives, resulting in increased light yields and improved gamma-ray energy resolution values relative to previously reported PS/PVT examples. Fast scintillation decay properties have also been characterized in the prepared scintillators, rivaling the kinetics of stilbene-doped bibenzyl and BC-422Q-1% while providing higher light yields than these reference materials.
