专利号:US-8314015-B2 优先权日:2010-07-14 标题 :Silicon surface modification for the electrochemical synthesis of silicon particles in suspension 发明人:TU CHANG-CHING; TANG LIANG; VOUTSAS APOSTOLOS T 权利人:TU CHANG-CHING; TANG LIANG; VOUTSAS APOSTOLOS T; SHARP LAB OF AMERICA INC 摘要:A process of silicon (Si) surface modification is provided for the electrochemical synthesis of Si particles in suspension. The process begins with a Si first substrate with a surface, and forms Si particles attached to the surface. Hydrogen-terminated Si particles are created and the first substrate is immersed in a hexane/1-octene (1/1 volume ratio) solution with a catalytic amount of chloroplatinic acid (H 2 PtCl 6 ). 1-octene is bonded with the hydrogen-terminated Si particles, creating modified Si particles, with octane capping ligands, attached to the substrate surface. The first substrate is then exposed to ultrasonication, separating the modified Si particles from the first substrate. After removing the first substrate, a suspension is created of modified Si particles suspended in excess hexane/1-octene.

In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

In aspects, the conversion of limiting reactants in the synthesis of asymmetrical sulfides unexpectedly remain high under increased flow rates through the catalyst bed, and under reduced temperatures and pressures. In further aspects, reactor systems configured for the independent synthesis of mercaptans and asymmetrical sulfides in a single fixed bed catalyst vessel are also disclosed as a simplification of existing reactor systems employing separate reactors for separate mercaptan and sulfide syntheses.
